Verdict
The clearest difference is price: COSA at Free against EndoData's $6.99. COSA also leads on update cadence (every 3 months vs every 5 months). EndoData's advantage is ads (none vs shown) and chart position (#197 vs unranked). On in-app purchases, device support and iOS requirement there is nothing between them.
