# BMI vs Go4 Tracker

The clearest difference is in-app purchases: Go4 Tracker at none against BMI's 1. Go4 Tracker also leads on ads (none vs shown) and update cadence (every 2 months vs every 6 months). BMI's advantage is iOS requirement (16 vs 18.6). On price and device support there is nothing between them.

Both are free to download. BMI sells 1 one-off in-app purchase. Go4 Tracker asks for nothing beyond the download.

BMI ships an update every 6 months, Go4 Tracker every 2 months. The most recent releases landed on October 14, 2026 and October 25, 2026 respectively.
