Verdict
The clearest difference is ads: Time to fast! at none against FastTime's shown. Time to fast! also leads on update cadence (every 3 days vs every 6 weeks) and monetization model (free vs ad-supported). FastTime's advantage is review sentiment (100% vs 71%) and device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.
