Verdict

The call

The clearest difference is in-app purchases: Weight Tracker ++ at none against BMI Calculator's 1. Weight Tracker ++ also leads on iOS requirement (15.0 vs 17.0). BMI Calculator's advantage is ads (none vs shown) and ratings volume (30K vs 723). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. BMI Calculator sells 1 one-off in-app purchase. Weight Tracker ++ asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Weight Tracker ++ holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: BMI Calculator has 30K ratings behind it against 723, so its average is the more settled of the two. Written reviews complicate that: 47% of BMI Calculator's written reviews are positive against 43% of Weight Tracker ++'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BMI Calculator ships an update fortnightly, Weight Tracker ++ monthly. The most recent releases landed on November 13, 2026 and November 11, 2026 respectively.
