# iECHO GPA vs Pilot Pro

The clearest difference is in-app purchases: iECHO GPA at none against Pilot Pro's 3. iECHO GPA also leads on rating (2.0 vs 1.6) and iOS requirement (12.0 vs 16.6). Pilot Pro's advantage is update cadence (monthly vs every 5 months) and review sentiment (29% vs 17%). On price, ratings volume and ads there is nothing between them.

Both are free to download. Pilot Pro sells 3 in-app purchases, starting at $34.99 per year. iECHO GPA asks for nothing beyond the download.

iECHO GPA holds the better App Store score, 2.0 against 1.6. Both are backed by a comparable volume of ratings — 3 and 7 respectively. Written reviews complicate that: 17% of iECHO GPA's written reviews are positive against 29% of Pilot Pro's, so the app with the better star average is not the one people write more warmly about.

iECHO GPA ships an update every 5 months, Pilot Pro monthly. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
