tiq

tiq is an iPhone to-do app built around a single day's checklist. It has no projects and no nested structure, only today's tasks. You can keep several daily checklists, add recurring tasks and routines, set time and location reminders, track your progress through the day, and choose when the lists reset.

Its main extra is Accountability Lock, which uses Screen Time to block distracting apps you pick until you finish a task. You can also share your checklists as images. No account is required, and the developer states that the app collects no data.

The app is free to download. tiq Pro adds unlimited tasks and lists, location reminders, premium themes, custom list colors and alternate app icons. It costs $1.49 a month or $9.99 for a lifetime plan. tiq requires iOS 26 and is available in English, French, German, Japanese, Portuguese and Spanish.
