# Stardust Period Tracker vs Forme Fasting Timer

The clearest difference is review sentiment: Stardust Period Tracker at 55% against Forme Fasting Timer's 0%. Stardust Period Tracker also leads on ratings volume (118K vs 1) and chart position (#42 vs unranked). Forme Fasting Timer's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Stardust Period Tracker sells 20 in-app purchases, starting at $2.99 per 7 days and Forme Fasting Timer sells 4 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Forme Fasting Timer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Stardust Period Tracker has 118K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 55% of Stardust Period Tracker's written reviews are positive against 0% of Forme Fasting Timer's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
