# Weight loss tracker vs BMI Diary

The clearest difference is in-app purchases: Weight loss tracker at none against BMI Diary's 1. Weight loss tracker also leads on rating (4.5 vs 4.1) and ratings volume (1K vs 7). BMI Diary's advantage is update cadence (every 3 weeks vs every 5 months). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. BMI Diary sells 1 one-off in-app purchase. Weight loss tracker asks for nothing beyond the download.

Weight loss tracker holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Weight loss tracker has 1K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 68% of Weight loss tracker's written reviews are positive against 75% of BMI Diary's, so the app with the better star average is not the one people write more warmly about.

Weight loss tracker ships an update every 5 months, BMI Diary every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
