CoTick is a to-do list you share. Groceries, trip packing, household chores: everyone sees the same list and checks things off together.
• Share with others: invite members and choose who can edit, who can only check items off, and who can only view
• Share in one tap: send a list's link with Messages, LINE and more; it opens straight to that list
• Works offline: keep checking items off without a connection; changes sync when you're back online
• Photos: add a photo to any item and tap to view it full screen
• Public lists: share a link anyone can view, even without an account
• Friends and groups: pick members faster from your friends and contact groups
• Sign in with Apple, Google or email, and link them to one account
• Available in English, 繁體中文, 简体中文 and 日本語
No ads. No tracking.
