# Fasting Tracker vs CalGPT

The clearest difference is ratings volume: Fasting Tracker at 9.1K against CalGPT's 2. Fasting Tracker also leads on update cadence (every 3 days vs every 9 days) and device support (4 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Fasting Tracker sells 17 in-app purchases, starting at $0.99 per month and CalGPT sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Fasting Tracker against 5.0 for CalGPT. That said, the two scores are not equally well evidenced: Fasting Tracker has 9.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 93% of Fasting Tracker's written reviews are positive against 100% of CalGPT's.

Fasting Tracker ships an update every 3 days, CalGPT every 9 days. The most recent releases landed on October 21, 2026 and October 10, 2026 respectively.
