Private productivity for iPhone
A todo list that stays quiet until you need more. Capture fast. Add details when they matter. Focus on one thing. Review what is still worth doing.
Simple outside. Powerful underneath.
OneTask keeps the main screen intentionally minimal. Tap a task only when you need context, planning or a checklist.
Search active, completed and archived tasks — including notes, #tags and checklist text.
Notes, dates, reminders, repeat rules, tags and checklists live in one native sheet.
OneTask surfaces tasks that have lingered for days so you can finish, reprioritize or archive them.
Add up to three simple tags such as #work, #home or #waiting and find them instantly through search.
Focus Task
Long-press a task, choose 25, 45 or 60 minutes, and OneTask becomes a single-task timer. Your countdown stays visible on the Lock Screen and Dynamic Island.
