Verdict
The clearest difference is ads: ArcFast at none against InterFasting's shown. ArcFast also leads on rating (5.0 vs 4.8). InterFasting's advantage is update cadence (every 4 days vs every 6 weeks) and ratings volume (352 vs 1). On price, in-app purchases and monetization model there is nothing between them.
