Verdict

The call

The clearest difference is price: Garmin GTN Trainer at Free against Prepware Instrument Pilot's $9.99. Garmin GTN Trainer also leads on rating (3.5 vs 2.6) and iOS requirement (13 vs 15.0). Prepware Instrument Pilot's advantage is chart position (#155 vs unranked) and ratings volume (45 vs 10). On update cadence, ads and in-app purchases there is nothing between them.

Garmin GTN Trainer holds the better App Store score, 3.5 against 2.6. Both are backed by a comparable volume of ratings — 45 and 10 respectively. Written reviews complicate that: 38% of Prepware Instrument Pilot's written reviews are positive against 30% of Garmin GTN Trainer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Prepware Instrument Pilot ships an update every 4 months, Garmin GTN Trainer every 7 months. The most recent releases landed on October 30, 2026 and October 23, 2026 respectively.
