# Artemis Mission Tracker vs One Light Day

The clearest difference is iOS requirement: One Light Day at 18.0 against Artemis Mission Tracker's 26.4. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Artemis Mission Tracker sells 7 in-app purchases, starting at $3.99 per month and One Light Day sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
