Verdict
The clearest difference is rating: Period Tracker at 4.4 against MyDays X's 3.2. MyDays X's advantage is update cadence (weekly vs fortnightly) and review sentiment (54% vs 44%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MyDays X sells 7 in-app purchases, starting at $7.99 per month and Period Tracker sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Period Tracker holds the better App Store score, 4.4 against 3.2. Both are backed by a comparable volume of ratings — 756 and 213 respectively. Written reviews complicate that: 54% of MyDays X's written reviews are positive against 44% of Period Tracker's, so the app with the better star average is not the one people write more warmly about.
MyDays X ships an update weekly, Period Tracker fortnightly. The most recent releases landed on September 23, 2026 and September 20, 2026 respectively.
