# Dose vs PeptideBros

The clearest difference is review sentiment: PeptideBros at 100% against Dose's 75%. PeptideBros also leads on rating (5.0 vs 4.7) and iOS requirement (15.0 vs 17.6). Dose's advantage is ratings volume (99 vs 5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Dose sells 3 in-app purchases, starting at $4.99 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 4.7. That said, the two scores are not equally well evidenced: Dose has 99 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 75% of Dose's written reviews are positive against 100% of PeptideBros's.

Dose ships an update every 2 weeks, PeptideBros every 3 weeks. The most recent releases landed on October 19, 2026 and October 2, 2026 respectively.
