SkyTimer automatically logs your flights and tracks fuel burn and tank changes in real time--from your wrist, phone, or iPad. A cockpit companion built to work alongside your EFB. Start a flight with a single tap. SkyTimer records block and flight times, tracks fuel quantity across up to 7 tanks and 4 engines, and logs your departure, arrival, and intermediate stop airports using a built-in worldwide airport database--no Internet required. *** FUEL MANAGEMENT, SIMPLIFIED *** SkyTimer calculates fuel burn, endurance, and remaining quantity on-the-fly using time-on-tanks and your configured burn rates. Update flow rates mid-flight for accuracy as conditions change. - Smart Balance calculates optimal tank timer durations to keep fuel balanced across tanks. - A robust reminder engine alerts you to configuration changes based on time-on-tank, fuel use, or fuel transferred. - Supports a wide range of fuel selectors and transfer switch types for single and multi-engine aircraft. *** AUTOMATIC FLIGHT TRACKING *** Smart Track uses GPS ground speed and your aircraft's Vso stall speed to automatically detect takeoffs and landings--no manual input needed. SkyTimer logs the times and airports for you. *** WORKS ON iPHONE, iPAD, AND APPLE WATCH *** Run SkyTimer on your iPad alongside your EFB in Split View, Windowed or Slide Over.

Verdict
The clearest difference is rating: AvNav at 4.2 against SkyTimer's 4.0. SkyTimer's advantage is ratings volume (22 vs 5) and device support (4 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SkyTimer sells 2 in-app purchases, starting at $2.49 per month and AvNav sells 1 in-app purchase, starting at $149.99 per year. Whichever you choose, the download price is not the number that matters.
AvNav holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 22 and 5 respectively. Written reviews complicate that: 54% of SkyTimer's written reviews are positive against 50% of AvNav's, so the app with the better star average is not the one people write more warmly about.
SkyTimer ships an update fortnightly, AvNav every 10 days. The most recent releases landed on October 7, 2026 and September 25, 2026 respectively.
