# Countdown vs Time Machine

The clearest difference is update cadence: Time Machine at fortnightly against Countdown's every 3 months. Time Machine also leads on ratings volume (10 vs 2) and iOS requirement (13 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Countdown sells 3 in-app purchases, starting at $1.49 per month and Time Machine sells 2 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Countdown against 4.5 for Time Machine. That said, the two scores are not equally well evidenced: Time Machine has 10 ratings behind it against 2, so its average is the more settled of the two.

Countdown ships an update every 3 months, Time Machine fortnightly. The most recent releases landed on September 20, 2026 and August 30, 2026 respectively.
