# Intermittent Fasting Tracker vs Fast AI

The clearest difference is review sentiment: Intermittent Fasting Tracker at 73% against Fast AI's 7%. Intermittent Fasting Tracker also leads on rating (4.9 vs 4.3) and ratings volume (29K vs 120). Fast AI's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Intermittent Fasting Tracker sells 14 in-app purchases, starting at $4.49 per month and Fast AI sells 5 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Intermittent Fasting Tracker holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Intermittent Fasting Tracker has 29K ratings behind it against 120, so its average is the more settled of the two. Written reviews point the same way: 73% of Intermittent Fasting Tracker's written reviews are positive against 7% of Fast AI's.

Intermittent Fasting Tracker ships an update every 8 days, Fast AI every 2 weeks. The most recent releases landed on October 30, 2026 and October 27, 2026 respectively.
