Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
