Verdict
The clearest difference is review sentiment: Sutro at 73% against Aiper's 47%. Sutro also leads on iOS requirement (12.4 vs 14.0). Aiper's advantage is rating (4.1 vs 3.9) and update cadence (every 3 weeks vs every 2 months). On price, ratings volume, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
Aiper holds the better App Store score, 4.1 against 3.9. Both are backed by a comparable volume of ratings — 175 and 260 respectively. Written reviews complicate that: 73% of Sutro's written reviews are positive against 47% of Aiper's, so the app with the better star average is not the one people write more warmly about.
Sutro ships an update every 2 months, Aiper every 3 weeks. The most recent releases landed on June 10, 2026 and September 24, 2026 respectively.
