# 16 vs Intermittent Fasting Kit

The clearest difference is monetization model: 16 at free with in-app purchases against Intermittent Fasting Kit's subscription. 16 also leads on update cadence (every 9 days vs every 6 weeks) and ratings volume (54 vs 1). Intermittent Fasting Kit's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 16 sells 3 in-app purchases, starting at $1.99 per month and Intermittent Fasting Kit sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Intermittent Fasting Kit holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 16 has 54 ratings behind it against 1, so its average is the more settled of the two.

16 ships an update every 9 days, Intermittent Fasting Kit every 6 weeks. The most recent releases landed on November 4, 2026 and September 28, 2026 respectively.
