TickTick

TickTick is a cross-platform to-do list and task manager from Appest Limited that syncs your tasks through the cloud across phone, tablet, computer and web. Beyond basic lists, it handles recurring tasks, checklists, multiple reminders per task, time- and location-based reminders, four priority levels and tags. Several calendar views let you see tasks alongside your schedule, and the app can connect with your existing calendar. TickTick also bundles tools that many people otherwise keep in separate apps: a Pomodoro-style focus timer, a habit tracker, and countdowns for birthdays and anniversaries. Lists can be shared with other people for collaboration, tasks can be added by email or with Siri, and attachments, descriptions and comments can be added to tasks. The core app is free, and a Premium subscription raises limits on lists, tasks, reminders, shared members and attachments while unlocking extras such as calendar subscriptions, a grid calendar view and custom smart lists. It suits anyone who wants planning, scheduling and habits in one place. For the iPhone Duo launch, the developer is running an App Store event announcing that TickTick is ready for the device's foldable screen.

TickTick's App Store in-app event "TickTick for iPhone Duo" (starting October 21, 2026) says the app is ready for iPhone Duo and gives users more room to view tasks, plan their schedule and stay organised on the foldable screen. The developer has not described an outer-display mode, Split View feature or other fold-specific behaviour, so it is listed as Adapted. DuoDiscover has not yet tested TickTick on an iPhone Duo.

TickTick is developed by Appest Limited.
