Verdict
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.

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.

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.
