# Reminder & Countdown vs Calculator

The clearest difference is ads: Calculator at none against Reminder & Countdown's shown. Calculator also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 16.0). Reminder & Countdown's advantage is rating (4.8 vs 4.4) and ratings volume (17K vs 5). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Reminder & Countdown holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Reminder & Countdown has 17K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 86% of Reminder & Countdown's written reviews are positive against 78% of Calculator's.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
