# Period Tracker vs SparkDuo

The clearest difference is review sentiment: SparkDuo at 100% against Period Tracker's 44%. SparkDuo also leads on rating (5.0 vs 4.4) and update cadence (weekly vs fortnightly). Period Tracker's advantage is ratings volume (213 vs 1) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Period Tracker sells 3 in-app purchases, starting at $3.99 per 7 days and SparkDuo sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

SparkDuo holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Period Tracker has 213 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 44% of Period Tracker's written reviews are positive against 100% of SparkDuo's.

Period Tracker ships an update fortnightly, SparkDuo weekly. The most recent releases landed on October 7, 2026 and October 6, 2026 respectively.
