# Cat Memory vs Birthdays Countdown

The clearest difference is rating: Birthdays Countdown at 4.7 against Cat Memory's 3.0. Birthdays Countdown also leads on ratings volume (46 vs 1). Cat Memory's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. Birthdays Countdown sells 4 in-app purchases, starting at $1.99 per month. Cat Memory asks for nothing beyond the download.

Birthdays Countdown holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Birthdays Countdown has 46 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of Cat Memory's written reviews are positive against 69% of Birthdays Countdown's, so the app with the better star average is not the one people write more warmly about.

Cat Memory ships an update every 4 weeks, Birthdays Countdown every 3 months. The most recent releases landed on October 19, 2026 and October 26, 2026 respectively.
