Hydrant Flow Test Calculator is a field-friendly calculation and reporting tool for fire protection professionals, engineers, inspectors, contractors, and AHJs who need to evaluate and document hydrant flow test results. The app helps calculate hydrant flow from field readings, compare available water supply against system demand, estimate downstream friction loss, and export professional PDF reports. Key features: • Calculate hydrant flow using static pressure, residual pressure, pitot pressure, outlet diameter, and discharge coefficients • Calculate total test flow and flow at a target residual pressure • Compare available supply against system or pump demand • Review demand pass/fail results with available pressure and safety cushion • View Supply vs Demand graph with demand point legend • Save completed test records to History • Add project information including associate, project number, project location, test hydrant tag, and flow hydrant tag • Optionally capture test hydrant and flow hydrant coordinates • Attach an image to a saved test record • Export PDF reports with project details, test summary, demand results, graph, location details, friction loss results, and attachment • Estimate friction loss using pipe product, nominal pipe size, inside diameter, pipe length, C-factor, elevation, minor loss, and device/backflow loss • Supports US and SI flow display The Friction Loss tool includes pipe product and nominal pipe size selection with automatic inside diameter lookup. Elevation guidance helps users enter positive values for uphill and negative values for downhill conditions. Hydrant Flow Test Calculator is designed to make field calculations faster, improve documentation consistency, and help organize hydrant flow test information in one place. This app is intended as a calculation and documentation aid. Users are responsible for verifying all inputs, assumptions, calculations, and results according to applicable codes, standards, project requirements, and professional judgment.

Need a work order form you can fill out on the job and hand to the customer? Workly turns the customer, the job, your labor hours and parts into a clean, printable work order PDF — no blank paper forms, no spreadsheet. Fill in the order number and date, the customer's details and the job description, add labor and parts lines, set a tax rate if you charge one, and tap Make Work Order PDF. • CUSTOMER AND JOB — customer name, phone, email and address, plus a job description and notes. Add your business name and contact details at the top if you like. • LABOR AND PARTS LINES — each line has a description, quantity or hours, and a rate or price; the amount is calculated for you. Up to 60 lines, continued onto extra pages when needed. • TOTALS DONE FOR YOU — labor subtotal, parts subtotal, optional tax and a bold total. • SIGNATURE LINES — spaces for the customer's and the technician's signature, each with a date line. • PRINT, SHARE OR SAVE — print on the spot, share the PDF, or save it to Files. Honest scope: Workly makes one work order at a time on US Letter pages; it doesn't keep a customer list, track payments or add a logo. Amounts are shown in your own currency, and decimal commas like 12,50 are read correctly. Signatures are signed by hand on the printed copy. Everything is made on your iPhone. Nothing is uploaded, and no account is needed. Try it free — 3 work orders. A one-time $4.99 purchase unlocks unlimited work orders. No subscription, no ads.

Verdict

The call

The clearest difference is in-app purchases: Hydrant Flow Test Calculator at none against Workly's 1. Hydrant Flow Test Calculator also leads on device support (3 vs 1). Workly's advantage is update cadence (every 3 days vs every 5 weeks). On price, ads and iOS requirement there is nothing between them.
