Verdict
The clearest difference is in-app purchases: Donec at none against Acute Calculator's 3. Acute Calculator's advantage is update cadence (every 2 days vs every 6 months) and ratings volume (117 vs 3). On price, review sentiment, ads and device support 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. Acute Calculator sells 3 one-off in-app purchases. Donec asks for nothing beyond the download.
Acute Calculator holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Acute Calculator has 117 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Donec's written reviews are positive against 95% of Acute Calculator's, so the app with the better star average is not the one people write more warmly about.
Donec ships an update every 6 months, Acute Calculator every 2 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
