# Reminder & Countdown vs Big Days

The clearest difference is in-app purchases: Reminder & Countdown at none against Big Days's 2. Reminder & Countdown also leads on ratings volume (16K vs 590) and rating (4.8 vs 4.6). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Big Days sells 2 one-off in-app purchases. Reminder & Countdown asks for nothing beyond the download.

Reminder & Countdown holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Reminder & Countdown has 16K ratings behind it against 590, so its average is the more settled of the two. Written reviews complicate that: 86% of Reminder & Countdown's written reviews are positive against 91% of Big Days's, so the app with the better star average is not the one people write more warmly about.

Reminder & Countdown ships an update every 3 months, Big Days every 4 months. Both last shipped on September 25, 2026.
