## What is Boat Fuel Gauge & Timer?

Most outboards and portable tanks have no fuel gauge you can trust. This app gives you an approximate one — and it gets smarter every time you fill up.

Tap START when the engine fires and STOP when you're done. The app tracks engine run-time and burns fuel down as you go, so you always know roughly how much is left and how far you can push it.

HOW IT WORKS
• Big START / STOP run timer — survives a crash, force-quit, or reboot without losing a running session
• Learns your burn rate (gallons per hour) automatically from each fill-to-full — no setup, and you can override it
• Shows fuel left, % remaining, range, and estimated time left — tap the gauge to switch the readout
• Pick a modern ring gauge or a classic needle dial

ON YOUR HOME SCREEN
• A widget shows the fuel ring with a START/STOP button — no need to open the app
• A Live Activity puts the live timer, fuel, and a STOP button on the Lock Screen and Dynamic Island
• The ring drains on its own — fuel is computed from time, so there's no background battery drain

EVERY TRIP, LOGGED
• Record the GPS route, distance, and speed of each run and see the track on a map
• Full history of every run, fill, and correction — edit or void any entry; nothing is ever truly deleted
• Lifetime engine hours for maintenance tracking
• Apple Watch companion with the same gauge and a START/STOP button on your wrist

BEYOND THE WATER
The same fuel math works for generators, RVs, and other fuel-burning engines — anything with a tank, a runtime, and no gauge you'd trust.

HOW ACCURATE IS IT?
It's an estimate, not a sensor. Fuel left = tank size − (run time × gallons-per-hour). Treat it as a dependable backup gauge and planning tool — not a replacement for keeping an eye on your actual tank.


## Version history (last 2 releases)

What's new in 1.1:

• Burn-rate history — the measured gal/h from every fill-up. Tap to edit, swipe to void.
• Tag your runs — name any run, even mid-run. Tags show on each run.
• Burn rate by tag — runs, hours, and a measured gal/h per activity. Mixed tanks stay honest.
• Set total engine hours — match your engine's hour meter. Display-only, reversible.

### 1.0 — 2026-06-24

No release notes.
