# Milligram vs Optimized Human

The clearest difference is ratings volume: Milligram at 313 against Optimized Human's 1. Milligram also leads on update cadence (every 4 days vs fortnightly). Optimized Human's advantage is rating (5.0 vs 4.7) and iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Milligram sells 3 in-app purchases, starting at $17.49 per month and Optimized Human sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Optimized Human holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Milligram has 313 ratings behind it against 1, so its average is the more settled of the two.

Milligram ships an update every 4 days, Optimized Human fortnightly. The most recent releases landed on October 12, 2026 and October 1, 2026 respectively.
