# BMI Calculator vs Simple BMI Calculator

The clearest difference is ads: Simple BMI Calculator at none against BMI Calculator's shown. Simple BMI Calculator also leads on rating (5.0 vs 4.6) and monetization model (free vs ad-supported). BMI Calculator's advantage is ratings volume (53 vs 1) and review sentiment (60% vs 50%). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Simple BMI Calculator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: BMI Calculator has 53 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of BMI Calculator's written reviews are positive against 50% of Simple BMI Calculator's, so the app with the better star average is not the one people write more warmly about.

BMI Calculator ships an update every 23 months, Simple BMI Calculator every 44 months. The most recent releases landed on November 1, 2026 and October 7, 2026 respectively.
