Fasting Tracker's advantage is update cadence (every 3 days vs every 9 days) and ratings volume (428 vs 54). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. 16 sells 3 in-app purchases, starting at $1.99 per month and Fasting Tracker sells 4 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
