# PepTracker vs PepOS

The clearest difference is ratings volume: PepTracker at 413 against PepOS's 1. PepOS's advantage is review sentiment (100% vs 77%) and rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PepTracker sells 2 in-app purchases, starting at $4.99 per month and PepOS sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

PepOS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PepTracker has 413 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 77% of PepTracker's written reviews are positive against 100% of PepOS's.

PepTracker ships an update every 2 weeks, PepOS fortnightly. Both last shipped on October 15, 2026.
