Verdict

The call

Intermittent Fasting and TDEE both sit at 4.8 stars, but that hides the real split: 90% of Intermittent Fasting's written reviews are positive against 36% of TDEE's. Intermittent Fasting also leads on ratings volume (15K vs 498). TDEE's advantage is monetization model (free with in-app purchases vs subscription) and ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Intermittent Fasting sells 6 in-app purchases, starting at $3.99 per 7 days and TDEE sells 1 one-off in-app purchase. 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 4.7 for TDEE.
