Verdict
The clearest difference is in-app purchases: マイ周期カレンダー at none against Period Tracker's 2. マイ周期カレンダー also leads on ads (none vs shown) and update cadence (every 10 days vs every 7 months). Period Tracker's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
