FEATURES OF FASTING TRACKER - Intermittent fasting tracker - Weight monitoring - Notifications about start/end of fasting and food window - Detailed analytics - Most popular 16/8 scheme and more - Fasting schedule - Weight sync with Apple Health IS IT EFFECTIVE? It’s proven that this healthy lifestyle leads to fast weight loss. During fasting, as your glycogen depletes, your body switches to ketosis, which is referred to as the body's "fat-burning" mode. This is an effective way to burn fat. IS IT SAFE? Yes. It’s the most natural and safe way to lose weight. Studies show that eating all the time makes your body unable to take a break from digesting. When you fast, you just take a break from eating, it takes some of the load off your liver. CAN I USE FASTING TRACKER? With various fasting plans, fasting tracker is suitable for beginner and experienced, men and women. It guides you through your plan. No need to change your diet, you can easily stick to it.

Verdict
The clearest difference is review sentiment: Intermittent Fasting at 50% against Fast AI's 7%. Intermittent Fasting also leads on rating (4.8 vs 4.3) and ratings volume (1K vs 120). Fast AI's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Fast AI sells 5 in-app purchases, starting at $5.99 per 7 days and Intermittent Fasting sells 10 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Intermittent Fasting holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Intermittent Fasting has 1K ratings behind it against 120, so its average is the more settled of the two. Written reviews point the same way: 7% of Fast AI's written reviews are positive against 50% of Intermittent Fasting's.
Both ship on a similar rhythm, roughly every 2 weeks. Both last shipped on November 3, 2026.
