About this app

Fire Sprinkler Tools is a professional Android utility for fire sprinkler field and design work.

Privacy-first workflow:

FST does not require an account. It does not include ads, analytics, tracking SDKs, cloud sync, or background upload. Saved reports and settings stay on the device unless the user chooses to export or share them.

Optional location and elevation helpers are user-triggered. Users remain in control of when coordinates are entered, looked up, exported, or shared.

Professional note:

Calculations and reports are intended as design and field aids. Users are responsible for verifying results against applicable NFPA standards, manufacturer data, local water authority requirements, project specifications, and AHJ requirements.
