Verdict

The call

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.
