# Countdown vs Calendro

The clearest difference is in-app purchases: Calendro at none against Countdown's 1. Countdown's advantage is iOS requirement (17.0 vs 26.5). On price, ads and device support there is nothing between them.

Both are free to download. Countdown sells 1 one-off in-app purchase. Calendro asks for nothing beyond the download.
