There’s an app (or several) to help every aspect of your plumbing business, ranging from free apps such as a basic spirit level to apps that calculate plumbing job measurements, conversions, and estimates to powerful business software apps that help manage all of your day-to-day operations and workflows.
Choosing the right app/s depends on your business needs and these key factors:
The size of your team
Your size and scaling goals
The features that you actually need and will use
The software’s ease of use
Your budget
If you have a small business with just a few plumbing techs and no plans to grow, free or low-cost apps may be all you need. However, if you want to scale your plumbing business while maintaining customer satisfaction and operational efficiency, an all-in-one field service management software solution (like ServiceTitan) that streamlines workflows like call booking, dispatching, scheduling, marketing, and reporting might be more suitable.
In this post, we share the 15 best plumbing apps, starting with a walk-through of our own, ServiceTitan. We then highlight apps ranging from basic utility tools that simplify routine tasks, such as measuring tight spaces, to advanced apps for tasks like invoicing and route planning.
We also feature five free online tools offered by ServiceTitan for plumbing contractors.

1. ServiceTitan: Best All-in-One Plumbing App
ServiceTitan is the leading all-in-one software solution for the home service industry. Our mobile app gives plumbers (and other home services businesses such as HVAC and electricians) the agility to work from any location and sync entire work orders with other team members (like CSRs and dispatchers) and plumbing business owners based in the office.
ServiceTitan Mobile replaces a whole range of paper-based processes because all customer documents — invoices, estimates, memberships, contracts, etc. — are uploaded to the cloud. It's intuitive to use and easy for techs (and the main office) to keep track of these important documents and access them on any device.
Features include the ability to:
Access all customer information collected by CSRs (job histories, equipment information, call recordings, and more).
Build instant digital estimates with accurate pricing and product information that customers can approve on the spot.
Offer financing options so that jobs can be closed more quickly.
Maximize upselling opportunities such as maintenance contracts that bring in more revenue.
Create invoices and take payments directly from customers so you get paid faster.
Sign-off timesheets remotely in real-time so payroll is accurate and prompt.
We’ll walk through these features next.
Access to Customer Information & Job History
With ServiceTitan Mobile, plumbers can access all the details your CSRs collected during the call booking process (contact details, job history, outstanding estimates, prior invoices, notes, and more). They can even listen to a recording of the call without ever having to call the CSR who made the booking.
This means that your plumbers arrive at every job fully informed and aware of the services previously performed and can discuss them with the customer in detail. This level of knowledge and attention to customer service gives customers additional confidence in the tech assigned to do the work.
Build Instant Digital Estimates
ServiceTitan lets plumbing businesses set up a dynamic flat-rate pricebook that’s updated across all devices and systems so you and your team can build accurate estimates that bring in profit.
Pricebook Pro comes loaded with curated content, detailed descriptions and vivid images already built in. Pricebook Pro also includes an “Upgrades and Recommendations” feature that shows customers good, better and best options, along with recommendations for required parts.
Using ServiceTitan Mobile, your plumbers can create Good-Better-Best proposals that show customers high-quality images of all products, and provide explainer videos and detailed product information on-site. Once a customer selects their option, ServiceTitan connects the estimate to the rest of the plumbing workflow, including scheduling, dispatching, and billing.
Offer Financing Options
ServiceTitan’s integrated financing feature helps your techs win more customers by offering flexible financing options while they’re out on a service call.
You control which plans you offer and set the rules to suit your plumbing business. Once you’ve built your estimate, ServiceTitan automatically calculates the options, based on your choices, so that financing can be offered directly from your mobile device.
The ability to offer flexible financing options on the spot gives customers instant access to funds and increases the likelihood of techs closing bigger jobs and boosting sales.
Maximize Upselling Opportunities
ServiceTitan Mobile gives your plumbing techs the tools to upsell maintenance contracts or close an outstanding estimate on all service calls.
Plumbing techs can use pre-approved maintenance agreement templates, present them to the customer, and get them signed while on a job.
Plumbing businesses can create the templates from scratch or adapt and improve on an existing agreement. You can set up and store as many templates as you wish, to suit different membership types, and customize them to include details such as membership duration, frequency, billing information, and pricing.
Without in-app information, identifying which customers need a maintenance contract, already have one, or require servicing or renewal is challenging. Techs can easily overlook upselling opportunities. When they have access to relevant customer details, they can follow up on open estimates and close more jobs.
Let Customers Pay for Products on the Spot
Collecting revenue as quickly as possible is crucial for keeping cash flow running smoothly. To do that, you need efficient and reliable billing procedures that integrate with your other operational processes and don’t take up techs’ time pulling together paperwork manually.
With ServiceTitan’s free Invoice Generator tool, plumbing techs can generate invoices while they’re on site, by inputting the relevant information into a customized invoice template and sending it directly to the customer via text or email.
Invoicing in this way saves time, looks professional, and reduces mistakes (such as pricing errors or lost paperwork).
Techs can also take payments directly from customers by capturing checks and credit cards via the mobile tablet camera, or you can add a credit card swiper. This is convenient for customers and means you get paid faster.
Note: If you already use accounting software, ServiceTitan’s invoicing software can be integrated with QuickBooks to ensure your financials are accurate, up-to-date, and easily accessible. We cover this below in our QuickBooks app section.
Sign Off TimeSheets Remotely
Instead of using a stand-alone timesheet app, ServiceTitan's payroll software has been designed to help you track staff (via timesheets), and pay them on time.
Our timesheet feature helps you manage productivity by monitoring time spent on specific activities, such as driving and collecting materials, as well as time spent on actual plumbing services.
Our software’s fully integrated features allow plumbing techs to access their timesheets from their mobile device, eliminating the need to drive to the head office each payroll period. Additionally, you can configure ServiceTitan to automate confidential commission and bonus structures, streamlining complex performance pay calculations.
These systems not only streamline your payroll procedure, but your plumbing staff will be confident that they will always be paid correctly and promptly.
ServiceTitan Mobile syncs seamlessly with all operational processes usually handled in the office. All features are fully integrated and accessible in real-time by team members, whether they are office-based or out in the field.
ServiceTitan plumbing software’s core features include:

ServiceTitan: Bonus Free Tools
These are not apps in the traditional sense, but ServiceTitan also offers the following free tools:
Bonus Tool 1: ServiceTitan Service Business Valuation Calculator
This interactive calculator offers business operators a snapshot of their companies’ monetary value.
Business owners input their company’s assets, revenue, number of employees, expenses, industry and state to offer a projected valuation. You don’t need a ServiceTitan account to use this tool and it's completely free to calculate the value of your business.
The calculator isn’t designed to offer financial advice. Instead, it functions as a self-help tool for business owners who are looking to track their growth or are considering selling their business.
Bonus Tool 2: ServiceTitan's Flow Rate Calculator
To calculate the flow rate of water inside a closed pipe, plumbers must understand complicated math formulas and know how to apply them on the job. ServiceTitan’s flow rate calculator makes determining volumetric flow rate quick and easy.
Bonus Tool 3: ServiceTitan's Pipe Volume Calculator
With ServiceTitan’s pipe volume calculator, you can easily calculate the volume of a pipe based on its inner diameter and length. Our calculator can also determine the weight of the water inside the pipe, making it a useful tool for professionals who need quick, accurate calculations in the field.
Bonus Tool 4: ServiceTitan’s Plumbing Labor Rate Calculator
ServiceTitan’s Plumbing Labor Rate Calculator helps you figure out the real cost of employing plumbers and calculates exactly how much your plumbing company should be charging customers for labor to maximize your bottom line.

2. ARPlan 3D: Best Interactive Experience App
iOS – Free version or $89.99 per year for full features
Android – Free version or $89.99 per year for full features
ARPlan 3D is a functional ruler app with augmented reality that measures any room in just a few minutes. The app uses special technology to measure surfaces and entire rooms. You can quickly measure the height, length, width and perimeter of a room in all units: feet, inches, millimeters, centimeters, meters, and yards.
The app also lets you calculate volumes of objects it detects, for example, how much a container such as a toilet or sink can hold. It is useful for plumbers or contractors who need to quickly present floor plans and visual representation of layouts to customers.
3. Best Flash Light: Best Flashlight App
iOS: Free version or $1.99
Plumbers often know this better than anyone else. It’s a huge hassle to juggle a heavy flashlight while trying to maneuver through a tight, dark space. The Best Flash Light app uses the front camera light on iPhone as a camera light and then allows you to zoom in on what you’re working on. You can also use your camera zoom flashlight with additional light.
The light operates via a “clap on/clap off” feature, or you can set up a timer so that the light turns off after a few minutes.
There is also a video view, which is useful, for example, if you need to read a reference number on the back of a piece of equipment. Simply turn on the light and video view and then read the label from the app.
4. Bubble Level: Best Spirit Level App
These plumbing apps may be two different apps, but they perform the same function. Each app is able to determine the horizontal or vertical alignment of a given surface. Essentially, these plumbing apps act as a replacement for a physical bubble or spirit level by utilizing the gyroscope in your phone to calculate the tilt angle along three different axes.
While iOS devices are generally calibrated correctly, Android devices come from multiple manufacturers and might not be as reliable.
Fortunately, the Android app includes the ability to manually recalibrate your device by placing it face-up on a flat surface and pressing the SET button. There’s also a RESET button to return to the default factory calibration at any time.
5. Code Snap UPC: Best App for Plumbing Codes
iOS – $7.99
Code Snap UPC is an app that helps experienced plumbers quickly access the Uniform Plumbing Code to see what code has been used on a job without searching through hundreds of pages or using your device's data.
While Code Snap references the most commonly used code needed on the job to cut down code book time, it doesn’t replace your UPC Code Book, which must be used alongside to comply with state laws.
6. CompanyCam: Best Camera App for Plumbers
CompanyCam is an innovative app built for contractors that lets you capture every part of your project photographically via your phone. You can take unlimited photos, annotate them with arrows, comments, and tags, and organize them by project and share them with your team and customers instantly.
All photos are location- and time-stamped, which is a useful feature if an issue comes up, and stored securely in the CompanyCam cloud.
7. EasyMeasure Camera Ruler: Best Dynamic Measuring App
iOS – Free or from $3.99
If you need to fit an appliance into a certain space, such as moving a large boiler or water heater through a narrow doorway, the EasyMeasure app can help. Just take a photo of the space on the app and let it calculate the room dimensions, angles, area, and even distance to the object.
While it sounds like magic, the app actually works on basic trigonometric principles. It uses the camera lens height and its tilt angle to calculate the distance to the object. Using that information, it determines an object’s height, width, and area.
The app even estimates how accurate it expects each particular measurement to be, so you’ll know when to use a tape measure instead.
The best feature of this app is its “dynamic photos” function, which lets you store photos and analyze measurements later. If you've ever left a job site and realized you missed an important measurement, you'll quickly see how valuable this feature is.
8. Pipe and Fitting: Best Visual Guide for Pipe Fitting
Android – Free
When it comes to pipe fitting, sometimes clear visuals help better than a wordy reference guide. With the Pipe and Fitting app, simply select from its comprehensive list of pipes, joints, clamps, and other parts available. The app calculates for you, with detailed specs for each part, including dimensions, hardness, tensile strength, yield strength, maximum load, and more.
The user-friendly app displays data with clearly illustrated technical diagrams, so you can see exactly how a part fits into any given plumbing system. And judging from the 2.5k reviews and an average 5-star rating, that visual element is an essential tool for users.
9. Pipe Trades Pro Calc: Best Pipe Calculator
It isn’t cheap, but among apps for plumbers, this one’s perfect for pipe calculations, and it features built-in, pipe-related data. It’s a great time-saver when cutting, welding and placing pipe, which likely offsets the app cost in the long run.
The plumbing app allows plumbers to choose a pipe material and type, then calculate diameters, wall thickness, filled weight per foot, and internal area, among other measurements.
The built-in calculations for cut lengths, odd-degree fittings, parallel pipe cutbacks, and pressure loss for any pipe size, type, or distance make this a must-have among apps for plumbers.
10. Plumbing Formulator: Best App for Solving Plumbing Equations
iOS – Free
As a plumber, you regularly need to solve complex equations in the field, such as calculating appropriate pipe sizes, determining water flow and pressure, or maximizing pump efficiency. Plumbing Formulator makes this process a whole lot easier with more than 120 standard formulas that you can easily check within the app.
The app also includes a number of great “quality-of-life” features — such as the ability to email and print specific formulas for easier reference. It also prominently displays your most frequently used formulas on the app for future use, and check out the handy graphical plumbing charts included to illustrate concepts in a clear manner.
With Plumbing Formulator, your techs can stop wasting valuable time searching online for each individual solution while in the field.
11. Plumbing Invoices: Best Invoicing App for Plumbers
iOS – Free or $49.99 per year for full features
If you don’t use software like ServiceTitan, it’s handy to be able to create invoices via your smartphone. The Plumbing Invoices app offers a host of features that help you create plumbing invoices as well as estimates and quotes.
With seven templates to choose from, you can add your own logo, sign invoices on your iPhone or iPad, and even schedule work via the app’s integration with your calendar. The app also has a database of more than 10,000 plumbing products that you can use to search for pricing information.
The free version is limited to three invoices, three estimates, and three clients.
12. Plumbing Systems Design Tables: Best Interactive Plumbing Handbook
iOS and Android – Free to ASPE members
This app, designed by the American Society of Plumbing Engineers (ASPE), offers a convenient reference for your plumbing techs when they’re in the field. Instead of thumbing through the 2,500-page handbook version just to find one specific table, they can access all of the data by clicking on the app.
It also comes with interactive calculators, which allow you to customize pipe materials and other design criteria, so it gives you the relevant sizing data in SI (International System of Units) or English. All U.S. standards and major plumbing codes are supported—including the International Plumbing Code (IPC), Uniform Plumbing Code (UPC), and National Standard Plumbing Code.
Please note: Only ASPE members can access the app’s full functionality.
13. QuickBooks: Best Accounting App for Plumbers
QuickBooks is one of the best business apps across several service industries, including the plumbing industry. From viewing net profit to tracking miles and managing financial reports and cash flow, it’s a one-stop shop in the app world.
Google Play reviewers tout the app’s real-time expense tracking and its ability to save detailed notes while your plumbers produce estimates. The app also helps techs manage payments, track sales and customers, view account balances and more.
Like most QuickBooks software, you’ll need to set up a subscription once you’ve completed a 14-day trial.
Note: ServiceTitan integrates with multiple types of accounting software, such as QuickBooks and Sage Intacct so it can easily be connected to your existing office systems.
14. Route4Me Route Planner: Best App for Route Planning
Efficient travel between multiple jobs is essential for plumbers and Route4Me is a great route optimization app.
This app enables users to load all service locations into the app, then it orders your stops to
maximize efficiency along the way. This separates the app from other navigation services and makes it a must-have among apps for plumbers.
This app becomes even more efficient if you have several techs out in the field at once. You’ll be able to squeeze more stops into your day by utilizing this efficiency builder.
15. Toggl Track: Best Time-Tracking App
iOS –Free for up to 5 users, subscriptions from $9 per month
Android – Free for up to 5 users, subscriptions from $9 per month
Toggl Track is a time-tracking app that helps you track how your plumbers are spending their time across desktop and mobile devices. The app integrates with Google and Outlook calendars and runs quietly in the background and syncs activity between devices.
The app lets you generate time-tracking reports so you can calculate the billable hours of your team. You can automatically round times up or down to the interval of your choice and keep track of productivity whenever you want by scheduling reports to be delivered to your inbox.
