# BMI Calculator 2025 vs Simple Fasting Tracker

BMI Calculator 2025 and Simple Fasting Tracker both sit at 5.0 stars, but that hides the real split: 78% of Simple Fasting Tracker's written reviews are positive against 0% of BMI Calculator 2025's. Simple Fasting Tracker also leads on ads (none vs shown). BMI Calculator 2025's advantage is update cadence (weekly vs fortnightly) and iOS requirement (12.0 vs 15.0).

Both are free to download. BMI Calculator 2025 sells 1 one-off in-app purchase and Simple Fasting Tracker sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

BMI Calculator 2025 holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 23 and 60 respectively. Written reviews complicate that: 0% of BMI Calculator 2025's written reviews are positive against 78% of Simple Fasting Tracker's, so the app with the better star average is not the one people write more warmly about.

BMI Calculator 2025 ships an update weekly, Simple Fasting Tracker fortnightly. The most recent releases landed on June 1, 2026 and September 24, 2026 respectively.
