Verdict
The clearest difference is rating: 6th Grade Math Tutor at 4.4 against Oky Period Tracker's 3.1. 6th Grade Math Tutor also leads on ratings volume (384 vs 47) and iOS requirement (13.0 vs 15.1). Oky Period Tracker's advantage is in-app purchases (none vs 1) and update cadence (every 6 weeks vs every 10 months). On price, ads and device support there is nothing between them.

6th Grade Math Tutor holds the better App Store score, 4.4 against 3.1. That said, the two scores are not equally well evidenced: 6th Grade Math Tutor has 384 ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 9% of 6th Grade Math Tutor's written reviews are positive against 33% of Oky Period Tracker's, so the app with the better star average is not the one people write more warmly about.
6th Grade Math Tutor ships an update every 10 months, Oky Period Tracker every 6 weeks. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
