# MarkDays vs Countdown

The clearest difference is ads: MarkDays at none against Countdown's shown. MarkDays also leads on device support (4 vs 2). Countdown's advantage is update cadence (every 3 weeks vs every 70 months). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. MarkDays sells 1 one-off in-app purchase and Countdown sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

MarkDays ships an update every 70 months, Countdown every 3 weeks. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
