Verdict

The call

The clearest difference is price: MyBook at Free against cMate's $1.99. MyBook also leads on update cadence (every 2 months vs every 69 months) and chart position (#103 vs unranked). cMate's advantage is in-app purchases (none vs 10) and iOS requirement (12.0 vs 15.0). On ads and device support there is nothing between them.
