# Premom vs Period

The clearest difference is in-app purchases: Period at none against Premom's 16. Premom's advantage is update cadence (weekly vs monthly) and ratings volume (61K vs 2.8K). On price, rating, ads and device support there is nothing between them.

Both are free to download. Premom sells 12 in-app purchases, starting at $9.99 per month. Period asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for Premom against 4.9 for Period. That said, the two scores are not equally well evidenced: Premom has 61K ratings behind it against 2.8K, so its average is the more settled of the two. Written reviews are what separate them: 70% of Premom's written reviews are positive against 54% of Period's.

Premom ships an update weekly, Period monthly. Both last shipped on October 30, 2026.
