Verdict

The call

The clearest difference is ratings volume: Intermittent Fasting at 1K against 16's 64. 16's advantage is update cadence (every 5 days vs every 2 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Intermittent Fasting sells 11 in-app purchases, starting at $3.99 per 7 days and 16 sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Intermittent Fasting against 4.9 for 16.
