# DOO vs ReminderStats

The clearest difference is ratings volume: ReminderStats at 5 against DOO's 1. ReminderStats also leads on device support (3 vs 1) and iOS requirement (15.6 vs 18.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. DOO sells 2 in-app purchases, starting at $0.99 per month and ReminderStats sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for DOO against 5.0 for ReminderStats. That said, the two scores are not equally well evidenced: ReminderStats has 5 ratings behind it against 1, so its average is the more settled of the two.

DOO ships an update fortnightly, ReminderStats every 11 days. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
