# Weight Tracker vs BMI

The clearest difference is review sentiment: Weight Tracker at 64% against BMI's 28%. Weight Tracker also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). BMI's advantage is rating (4.7 vs 4.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Weight Tracker sells 13 in-app purchases, starting at $4.99 per month 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, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Weight Tracker has 1K ratings behind it against 200, so its average is the more settled of the two. Written reviews complicate that: 64% of Weight Tracker's written reviews are positive against 28% of BMI's, so the app with the better star average is not the one people write more warmly about.

Weight Tracker ships an update weekly, BMI every 3 weeks. Both last shipped on October 29, 2026.
