# CalcRx vs Rx Corner

The clearest difference is in-app purchases: Rx Corner at none against CalcRx's 2. Rx Corner also leads on update cadence (every 6 weeks vs every 10 months) and rating (4.9 vs 4.7). CalcRx's advantage is ads (none vs shown). On price, review sentiment, monetization model and device support there is nothing between them.

Both are free to download. CalcRx sells 2 in-app purchases, starting at $0.99 per month. Rx Corner asks for nothing beyond the download.

Rx Corner holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 15 and 49 respectively. Written reviews complicate that: 100% of CalcRx's written reviews are positive against 95% of Rx Corner's, so the app with the better star average is not the one people write more warmly about.

CalcRx ships an update every 10 months, Rx Corner every 6 weeks. The most recent releases landed on September 11, 2026 and September 27, 2026 respectively.
