Verdict
The clearest difference is review sentiment: BMI Diary at 75% against BMI's 0%. BMI Diary also leads on update cadence (every 3 weeks vs every 6 months) and iOS requirement (12.0 vs 16). BMI's advantage is rating (4.9 vs 4.1) and ratings volume (56 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. BMI Diary 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 4.1. That said, the two scores are not equally well evidenced: BMI has 56 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 75% of BMI Diary'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.
BMI Diary ships an update every 3 weeks, BMI every 6 months. The most recent releases landed on October 24, 2026 and October 14, 2026 respectively.
