Built for the field, not the office

FireTools is a suite of 10 focused calculators for working tradespeople. Each app does one job and does it fast — no bloated menus, no sign-in, no spinner waiting on a connection. Open it on the ladder or in the truck and get an answer in seconds.

Every result is backed by NFPA 13/14/72 and shows the exact code reference behind the math, so you can check it against the book or hand it to an inspector with confidence. Calculations run entirely on your device — your inputs never leave your phone.

Start free with rewarded ads, then unlock Pro for a one-time $2.99 per app to remove ads, save unlimited history, and export clean PDF reports. No subscriptions, ever.

Frequently asked questions

Are these calculators free?

Yes. Every app is free to use with rewarded ads. A one-time $2.99 Pro unlock removes ads, saves unlimited calculation history, and enables PDF export — there is no subscription.

Do they work without internet?

Completely. All FireTools apps run 100% offline with no account required, so they work in a basement, a mechanical room, or anywhere with no signal.

Which code edition do they follow?

Calculations are validated against NFPA 13/14/72 (current revision). Each result shows the specific article or table it is based on so you can verify it.

Are they on iPhone and Android?

Yes — FireTools apps are available on both the App Store and Google Play. Open any calculator above to get the download links.
