# DietSensor Fasting vs 16

The clearest difference is review sentiment: 16 at 100% against DietSensor Fasting's 50%. 16 also leads on update cadence (every 6 weeks vs every 3 months). DietSensor Fasting's advantage is rating (5.0 vs 4.0) and ads (none vs shown). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. DietSensor Fasting sells 9 in-app purchases, starting at $29.99 per 3 months and 16 sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

DietSensor Fasting holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 5 and 4 respectively. Written reviews complicate that: 50% of DietSensor Fasting's written reviews are positive against 100% of 16's, so the app with the better star average is not the one people write more warmly about.

DietSensor Fasting ships an update every 3 months, 16 every 6 weeks. The most recent releases landed on August 14, 2026 and September 17, 2026 respectively.
