# Stacky vs Day

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

Both are free to download. Stacky sells 1 one-off in-app purchase and Day sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Stacky ships an update every 3 weeks, Day every 3 days. The most recent releases landed on September 19, 2026 and September 20, 2026 respectively.
