Verdict
The clearest difference is rating: OASTH at 3.7 against OASA's 2.7. OASA's advantage is update cadence (every 2 weeks vs every 2 months). On price, review sentiment, ratings volume 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. Neither carries in-app purchases, so what you see is what you pay.
OASTH holds the better App Store score, 3.7 against 2.7. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 7% of OASTH's written reviews are positive against 14% of OASA's, so the app with the better star average is not the one people write more warmly about.
OASTH ships an update every 2 months, OASA every 2 weeks. The most recent releases landed on June 24, 2026 and September 18, 2026 respectively.
