Verdict
The clearest difference is review sentiment: Nautide at 67% against iMar's 29%. Nautide also leads on update cadence (every 3 months vs every 10 months) and chart position (#60 vs unranked). iMar's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.
