# BMI vs BMI Calculator + Tracker

The clearest difference is in-app purchases: BMI Calculator + Tracker at none against BMI's 1. BMI Calculator + Tracker also leads on ads (none vs shown) and update cadence (every 5 days vs every 6 months). BMI's advantage is ratings volume (56 vs 4). On price, rating, device support and iOS requirement there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.9 for BMI against 5.0 for BMI Calculator + Tracker. That said, the two scores are not equally well evidenced: BMI has 56 ratings behind it against 4, so its average is the more settled of the two.

BMI ships an update every 6 months, BMI Calculator + Tracker every 5 days. The most recent releases landed on June 26, 2026 and September 9, 2026 respectively.
