Verdict

The call

The clearest difference is in-app purchases: Rhythm at none against FastiMate's 3. Rhythm also leads on ratings volume (458 vs 1). FastiMate's advantage is update cadence (every 3 weeks vs every 13 months) and rating (5.0 vs 4.7). On price, ads, device support and iOS requirement there is nothing between them.
