New Fire Flow calculator using the National Fire Academy formula. Wye Ops now shows each line's PDP and the pressure to gate the lower line down to. Advanced Wildland is out of Beta. Refreshed, consistent design across every screen.

Advanced Wildland rebuilt with friction loss based on actual flow, using BLM wildland hose data. New Flow and Hose Type (Lined or Weeping) selectors. One clear go/no-go pump check, with max lay and max elevation. Wildland Pumps layout fixed on iPad.

Improved iPad layout with correctly sized icons. Consistent header typography across all screens. Stability improvements.

Version 2.3 WYE OPS New calculator for a supply line feeding a wye with two attack lines. Enter each line as it is. The app pumps to the line that needs the most pressure and tells you which line to gate. STANDPIPE New Standpipe line type adds 25 psi for the system and takes elevation in floors at 5 psi per floor. Results over 200 psi show an amber caution. Layout and Instructions improvements.

Version 2.2 SWIPE BETWEEN SCREENS Swipe left or right to move between Structural Ops, Wildland Pumps and Advanced Wildland. Your inputs stay put as you switch. MIXED LINES GUIDE New Instructions card showing how to calculate wye and mixed hose lays in two parts. SMALLER SCREENS Layout improvements for iPhone SE and other compact iPhones, plus a menu fix on iPad.

Version 2.1: Hydraulics aligned to IFSTA. APPLIANCE LOSS Appliance loss now follows IFSTA: 10 psi per appliance at 350 gpm or more, and none below 350 gpm. Nothing is added when no appliances are selected. LINE TYPE New Line Type menu: Hoseline, Master Stream (adds 25 psi for the device at any flow) or Relay (uses the 20 psi minimum intake pressure). 80 PSI NOZZLE PRESSURE Added for smooth bore master streams. CALCULATION BREAKDOWN Tap the Pump Discharge Pressure result to see nozzle pressure, friction loss, elevation and appliance loss. Updated Instructions and improved metric accuracy.

Version 2.0 — Major update. VISUAL OVERHAUL Completely redesigned background and splash screen. New full-screen launch experience before the app loads. VERIFIED PUMP DATA All built-in wildland pump specs have been audited and corrected against manufacturer documentation. Engine specs, fuel type, weight, and performance curves are now fully accurate. Fuel Type field added to all pump cards. ANDROID LAUNCH Fire Pump Calc is now available on Android. Same calculations, same pump data, rebuilt natively in Jetpack Compose. UI IMPROVEMENTS Pump picker redesigned with a dark floating style matching the app aesthetic. Max Head label corrected to Max Head Pressure throughout. Bug fixes and performance improvements across all screens.

Version 1.9 — Significant update across all screens. CUSTOM PUMP BUILDER Add your own pump specs and save them for future use. Custom pumps appear in both the Wildland Pump Specs reference and the Advanced Wildland calculator. Delete custom pumps anytime. METRIC / IMPERIAL TOGGLE Structural Operations now supports metric display. Toggle between PSI/GPM/ft and kPa/L·min/m from the menu. Imperial by default. ADVANCED WILDLAND IMPROVEMENTS Hose length options now adjust automatically based on selected diameter. Nozzle type defaults to the correct nozzle for each hose size. Tank Fill % replaces Water Fill %. Negative elevation support added to Structural Operations. INSTRUCTIONS SCREEN Built-in reference guide covering all three calculators — inputs, outputs, and operational notes. Accessible from the main menu. LEAVE A REVIEW Enjoying the app? A review button is now in the About screen. Takes 10 seconds and helps other operators find the tool.

What's new: - Logo credit updated in the About screen - Structural Operations labels cleaned up for clarity Version history highlights: - 1.7 — Disclaimer and About screens fully redesigned, About converted to full screen, iPad menu improvements, 4" hose diameter added to Structural Operations - 1.6 — Wildland Pump Specs reference screen added with five pump models and full performance data, Advanced Wildland Calculations screen (early access), visual refresh across all screens - 1.5 — First-launch disclaimer gate, usage disclaimer, copyright update - 1.4 and earlier — Core PDP calculator, hose diameter and flow rate pickers, elevation and appliance loss

Version 1.7 brings visual and usability improvements across all screens: - Disclaimer and About screens fully redesigned to match the app theme - About page converted to a full screen for better readability - iPad menu improved — no more scrolling required - 4" hose diameter added to Structural Operations - Background and card styling refined throughout

Version 1.6 introduces two new tools for fire service pump operations: Wildland Pump Specs — a quick-reference guide covering five common portable pump models used in wildland firefighting. View performance curves, engine specs, max pressure, flow rates, and head pressure data at a glance — no internet required. Advanced Wildland Calculations (Early Access) — a hydraulic calculator for wildland pump operations, including friction loss, elevation, max hose lay, and runtime estimates. Also includes a visual refresh across all screens.

Version 1.5 adds full crew credits, updated copyright information, and organization name correction. General polish and stability improvements throughout.
