Verdict

The call

The clearest difference is ratings volume: Clue Period & Cycle Tracker at 404K against Moody Month's 883. Clue Period & Cycle Tracker also leads on rating (4.8 vs 4.6) and chart position (#23 vs unranked). Moody Month's advantage is review sentiment (55% vs 42%) and iOS requirement (15.2 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Clue Period & Cycle Tracker sells 11 in-app purchases, starting at $9.99 per month and Moody Month sells 12 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Clue Period & Cycle Tracker holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Clue Period & Cycle Tracker has 404K ratings behind it against 883, so its average is the more settled of the two. Written reviews complicate that: 42% of Clue Period & Cycle Tracker's written reviews are positive against 55% of Moody Month's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Clue Period & Cycle Tracker ships an update weekly, Moody Month every 10 days. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
