## What is Tsugi?

Turn your iPhone into a dedicated to-do deviceTsugi is a to-do app built for one thing: focusing on your tasks. Start Focus Mode and every app you've selected gets blocked. The screen switches to a dark, battery-friendly always-on display that's easy on the eyes, showing only the task at hand. Place it on your desk, and it's no longer a smartphone — it's your personal to-do device.■ Made for you if…

Your phone keeps pulling you away from work
You want to practice focus methods like Pomodoro
You'd like your iPhone to act as a "what I'm doing now" display while you work
■ Key Features◆ App Blocking
Powered by Apple's Screen Time. While you focus, social media and games stay locked. You choose exactly which apps to block.◆ Focus Mode
A pure black screen with nothing but your task name and a ring timer. Brightness dims automatically (manual adjustment available) and the screen stays on without sleeping. To prevent accidental exits, you can only end a session with a long press.◆ Capture ideas without breaking focus
Add and edit tasks without leaving Focus Mode. Just hit return to keep entering tasks one after another. Set time estimates (15/25/50/90 min) with a single tap.◆ Track your progress
See your focus time for today and this week, completed tasks, and streaks. The more you keep at it, the more you'll see.■ Privacy
Tsugi never collects or transmits data about which apps you use or when. All task data is stored locally on your device.■ Before you start

App Blocking requires Screen Time permission (you can set this up on first launch)
Requires iOS 16 or later
