Verdict
The clearest difference is review sentiment: Watch Weight at 47% against BMI's 0%. Watch Weight also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). BMI's advantage is rating (4.9 vs 4.2). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Watch Weight sells 1 one-off in-app purchase and BMI sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
BMI holds the better App Store score, 4.9 against 4.2. Both are backed by a comparable volume of ratings — 45 and 56 respectively. Written reviews complicate that: 47% of Watch Weight's written reviews are positive against 0% of BMI's, so the app with the better star average is not the one people write more warmly about.
Watch Weight ships an update every 4 months, BMI every 6 months. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
