Verdict

The call

The clearest difference is in-app purchases: Rectangular Mosaic at none against Cover's 1. Rectangular Mosaic also leads on ads (none vs shown). Cover's advantage is update cadence (every 3 months vs every 7 months) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
