# Timezone Planner vs One Habit

The clearest difference is in-app purchases: Timezone Planner at none against One Habit's 1. One Habit's advantage is iOS requirement (15.0 vs 18.0). On price, ads and device support there is nothing between them.

Both are free to download. One Habit sells 1 one-off in-app purchase. Timezone Planner asks for nothing beyond the download.
