# Fast AI vs Intermittent Fasting Tracker Х

The clearest difference is review sentiment: Intermittent Fasting Tracker Х at 89% against Fast AI's 7%. Intermittent Fasting Tracker Х also leads on rating (5.0 vs 4.3). Fast AI's advantage is ratings volume (120 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Fast AI sells 5 in-app purchases, starting at $5.99 per 7 days and Intermittent Fasting Tracker Х sells 11 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
