# Tempdrop vs PeakDay Fertility Tracker App

The clearest difference is rating: Tempdrop at 4.2 against PeakDay Fertility Tracker App's 3.1. Tempdrop also leads on ratings volume (714 vs 27). PeakDay Fertility Tracker App's advantage is review sentiment (60% vs 39%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Tempdrop sells 6 in-app purchases, starting at $2.99 per month and PeakDay Fertility Tracker App sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Tempdrop holds the better App Store score, 4.2 against 3.1. That said, the two scores are not equally well evidenced: Tempdrop has 714 ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 39% of Tempdrop's written reviews are positive against 60% of PeakDay Fertility Tracker App's, so the app with the better star average is not the one people write more warmly about.

Tempdrop ships an update every 2 months, PeakDay Fertility Tracker App every 6 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
