Task Control Tower
To-Do & Handwritten Notes
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Line up today's work as strips, focus on the one you're working on, and slide it right into the tray when it's done. Task Control Tower borrows the flight strips air traffic controllers use to handle planes one at a time, and pairs them with handwritten notes.
■ Focus on today
• Put today's tasks in the pending queue and reorder them with a long press
• Only one task is in progress at a time, so you can stay on it
• Slide a strip right to finish it and drop it into the tray. Undo right away if it was a mistake
• What you didn't finish stays as "carried over" the next day
• Priorities (high, normal, low) shown in color and words, plus due dates and time estimates
• Switch between the Today and All views
■ Handwritten notes
• Keep notes in books of A4 sheets, by hand with Apple Pencil or your finger, or as text
• Link notes to tasks and open them while you work
• Export as PDF or images to share or print
• On iPad, keep your tasks and notes side by side
■ Calendar events
• Today's events from your iPhone's calendar appear in the same column as your tasks
• Slide finished events to mark them done and leave a note on the event
• Create new events from the app
■ Private and dependable
• No account needed. Your data stays on your device and works offline
• Sync between devices is encrypted on your device before it's sent, so not even we can read it
• Move your data to another device with a backup file
• Works with VoiceOver, larger text and Reduce Motion
■ Pricing
The basic features are free, with ads.
• Free plan: up to 10 pending strips shown, 5 active note books, and 7 days of history
• Remove Ads (one-time purchase): no more ads

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Tasks and calendar events now share one list, and events can be reordered by long press too. New tasks and events slot in by date, and the order stays as you set it
• The views are now Today, Tomorrow and All; the app opens in All
• Events are read up to three months ahead and show their date outside Today
• In Tomorrow and All, a future task can be brought to today with "To today"
