Verdict
The clearest difference is in-app purchases: RotaStone at none against Combinate's 1. RotaStone also leads on update cadence (every 2 months vs every 6 months) and iOS requirement (12.0 vs 15.6). Combinate's advantage is ads (none vs shown). On price and device support there is nothing between them.
