Verdict
The clearest difference is ads: Relief Central at none against AIM Clinical Cases's shown. Relief Central also leads on ratings volume (924 vs 2) and iOS requirement (15.0 vs 17.0). AIM Clinical Cases's advantage is rating (5.0 vs 4.6) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.
