Verdict
The clearest difference is in-app purchases: Kendamil Study at none against WavelyDx's 9. Kendamil Study also leads on ads (none vs shown). WavelyDx's advantage is update cadence (every 3 weeks vs every 2 months) and chart position (#189 vs unranked). On price, device support and iOS requirement there is nothing between them.
