# Peptide Tracker vs 4D Coaching

The clearest difference is update cadence: 4D Coaching at weekly against Peptide Tracker's fortnightly. 4D Coaching also leads on iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide Tracker sells 11 in-app purchases, starting at $0.99 per 7 days and 4D Coaching sells 1 in-app purchase, starting at $129.99 per month. Whichever you choose, the download price is not the number that matters.

Peptide Tracker ships an update fortnightly, 4D Coaching weekly. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
