# Empty vs DietSensor Fasting

The clearest difference is rating: DietSensor Fasting at 5.0 against Empty's 4.5. DietSensor Fasting also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.6). Empty's advantage is review sentiment (70% vs 50%) and ratings volume (95 vs 5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Empty sells 1 one-off in-app purchase and DietSensor Fasting sells 9 in-app purchases, starting at $29.99 per 3 months. Whichever you choose, the download price is not the number that matters.

DietSensor Fasting holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Empty has 95 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 70% of Empty's written reviews are positive against 50% of DietSensor Fasting's, so the app with the better star average is not the one people write more warmly about.

Empty ships an update every 6 months, DietSensor Fasting every 3 months. The most recent releases landed on September 26, 2026 and October 7, 2026 respectively.
