FuelAware

Built by an Aerospace Engineer and GA pilot. Fuel tank swap timers on your Lock Screen, true cross-country GPH and cost-per-leg analytics. Your totalizer's missing half.

Your totalizer knows how much fuel you've burned. It has no idea which tank it came from — or what it cost you. FuelAware does.

FuelAware is an in-flight fuel management assistant for general aviation pilots flying multi-tank aircraft. Enter your totalizer reading at each tank swap and FuelAware handles the per-tank accounting in flight — then converts every leg into hard data: real cross-country burn rates, true cost per leg, and trip-level analysis your kneeboard math could never keep up with.

TRACK EVERY TANK

Live animated fuel gauges deplete in real time as you fly Log swaps and checkpoints with a single totalizer entry Swap countdown with two modes: balanced swaps or run-to-planned-empty Configurable safety reserve with escalating low-fuel warnings

NEVER MISS A SWAP

Live Activity puts your swap timer, leg time, current tank, and GPH on the Lock Screen and Dynamic Island — no unlocking mid-flight Five escalating alerts before each swap, plus overrun warnings Crash recovery: if your phone dies mid-leg, resume right where you left off

KNOW YOUR REAL NUMBERS

Three GPH views at a glance: current segment, leg average, and burn-cycle average — your true cross-country burn rate across every leg between refuels Pilot-observed GPH entries refine swap and endurance predictions piecewise Multi-leg burn cycles tracked automatically: fly three legs without refueling and FuelAware treats them as one continuous data set

KNOW WHAT EVERY LEG COSTS

Every gallon burned is priced at what you actually paid for it — newest fuel first, older fuel at its blended price Per-leg burn cost locks in at shutdown; FBO fees, parking, and misc charges tracked per stop Combine legs into trips: total burn, engine time, average GPH, and effective cost per gallon roll up automatically — even across nested multi-day master trips Receipt reconciliation: compare tracked burn against what the pump put in, color-coded variance per stop

YOUR AIRCRAFT, MODELED RIGHT

25+ templates verified against POH and FAA type certificate data: Cessna 172/182/210, Piper Cherokee through Saratoga and Comanche, Beechcraft Bonanza line, Mooney M20C/J/R Filler-neck tab support — TOP OFF, TAB FILL, or custom per-tank quantities Build any aircraft: up to 6 tanks, AVGAS or Jet-A Fly multiple aircraft, each with its own saved fuel state and price history

LOG IT, PROVE IT, SHARE IT

Professional PDF reports per leg or trip — cost analysis, burn cycles, full swap logs AirDrop your complete dataset between devices — smart merge, no cloud required

PRIVATE BY DESIGN No accounts. No servers. No analytics. Your flight data lives on your device, period.

FuelAware was built and flight-tested by a pilot in a 4-tank Cherokee Six because the fuel-selector-timer-and-sticky-note system deserved to be retired.

IMPORTANT: FuelAware is a situational-awareness aid. It is not a substitute for preflight fuel planning, your fuel totalizer, fuel gauges, visual tank checks, or POH procedures. Always verify fuel quantity before flight and manage fuel per your POH.

FuelAware requires an auto-renewable subscription to use — $8.99/month or $79.99/year, each with a 7-day free trial. All features require an active subscription.
