Verdict
The clearest difference is rating: Sonus at 5.0 against Intermittent Fasting's 3.8. Intermittent Fasting's advantage is price ($0.99 vs $3.99) and update cadence (every 6 weeks vs every 3 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
