Verdict

The call

The clearest difference is review sentiment: Nice at 75% against Flo Cycle & Period Tracker's 46%. Flo Cycle & Period Tracker's advantage is ratings volume (2M vs 4.9K) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Flo Cycle & Period Tracker sells 10 in-app purchases, starting at $1.99 per 7 days and Nice sells 6 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Flo Cycle & Period Tracker holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Flo Cycle & Period Tracker has 2M ratings behind it against 4.9K, so its average is the more settled of the two. Written reviews complicate that: 46% of Flo Cycle & Period Tracker's written reviews are positive against 75% of Nice's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flo Cycle & Period Tracker ships an update every 9 days, Nice weekly. The most recent releases landed on November 10, 2026 and November 9, 2026 respectively.
