# Regimen vs PeptideBros

The clearest difference is ratings volume: Regimen at 539 against PeptideBros's 5. Regimen also leads on update cadence (weekly vs every 3 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Regimen sells 2 in-app purchases, starting at $7.99 per month and PeptideBros sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

PeptideBros holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Regimen has 539 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 94% of Regimen's written reviews are positive against 100% of PeptideBros's.

Regimen ships an update weekly, PeptideBros every 3 weeks. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
