Verdict
The clearest difference is ads: Premom at none against Lu Period Tracker, Ovulation's shown. Premom also leads on ratings volume (61K vs 89) and rating (4.8 vs 4.5). Lu Period Tracker, Ovulation's advantage is review sentiment (83% vs 70%). On price, update cadence, 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. Premom sells 9 in-app purchases, starting at $12.99 per month and Lu Period Tracker, Ovulation sells 7 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Premom holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Premom has 61K ratings behind it against 89, so its average is the more settled of the two. Written reviews complicate that: 70% of Premom's written reviews are positive against 83% of Lu Period Tracker, Ovulation's, so the app with the better star average is not the one people write more warmly about.
Premom ships an update weekly, Lu Period Tracker, Ovulation every 2 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
