Verdict

The call

The clearest difference is review sentiment: HarmLess at 83% against BMI Calculator's 9%. HarmLess also leads on ratings volume (9.1K vs 1). BMI Calculator's advantage is in-app purchases (none vs 14) and ads (none vs shown). On price and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

BMI Calculator holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HarmLess has 9.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of HarmLess's written reviews are positive against 9% of BMI Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HarmLess ships an update fortnightly, BMI Calculator weekly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
