Verdict

The call

The clearest difference is in-app purchases: iMar at none against My Tides's 2. iMar also leads on iOS requirement (10.0 vs 18.0). My Tides's advantage is update cadence (every 3 days vs every 10 months) and device support (4 vs 2). On price, review sentiment and ads there is nothing between them.
