# Regimen vs PeptideFox

The clearest difference is monetization model: PeptideFox at free against Regimen's freemium. PeptideFox also leads on rating (5.0 vs 4.8). Regimen's advantage is ratings volume (532 vs 4) and device support (3 vs 1). On price, review sentiment, update cadence 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 PeptideFox sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

PeptideFox holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Regimen has 532 ratings behind it against 4, 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 PeptideFox's.

Both ship on a similar rhythm, roughly weekly. Both last shipped on October 24, 2026.
