# DietSensor Fasting vs FastFit

The clearest difference is review sentiment: FastFit at 100% against DietSensor Fasting's 50%. FastFit also leads on update cadence (every 3 weeks vs every 3 months).

Both are free to download. DietSensor Fasting sells 9 in-app purchases, starting at $29.99 per 3 months and FastFit sells 4 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
