# Period Log vs Period Tracker

The clearest difference is update cadence: Period Tracker at every 6 weeks against Period Log's every 7 months. Period Tracker also leads on iOS requirement (12.0 vs 15.6). Period Log's advantage is monetization model (ad-supported vs free with in-app purchases) and ratings volume (1.2K vs 151). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Period Tracker holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Period Log has 1.2K ratings behind it against 151, so its average is the more settled of the two. Written reviews point the same way: 92% of Period Log's written reviews are positive against 96% of Period Tracker's.

Period Log ships an update every 7 months, Period Tracker every 6 weeks. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
