# Coimin vs DokuDoo

The clearest difference is ads: DokuDoo at none against Coimin's shown. DokuDoo also leads on update cadence (every 6 days vs every 3 weeks). Coimin's advantage is iOS requirement (15.6 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Coimin sells 1 in-app purchase, starting at $0.99 per month and DokuDoo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Coimin ships an update every 3 weeks, DokuDoo every 6 days. Both last shipped on November 8, 2026.
