Crux: One Task a Day

Stop drowning in endless to-do lists.
Crux is built on one simple idea: you don't need to do everything — you need to do the one thing that matters most.
Every morning, set your single most important task. That's it. No categories, no priorities, no sub-tasks. Just one thing to focus on today.
When you complete it, celebrate. Then come back tomorrow and do it again.
How Crux works:
→ Open the app each morning
→ Set your ONE task for the day
→ See it displayed front and center
→ Mark it complete when you're done
→ Build a streak of focused, productive days
Why one task?
Most productivity apps fail because they help you collect tasks, not complete them. You end up with 47 items across 6 lists, feeling more overwhelmed than when you started.
Crux takes the opposite approach. By forcing you to choose just one thing, you're forced to prioritize. And when you focus on one thing, you actually get it done.
Features:
• Set one daily task in seconds
• Clean, distraction-free interface
• Satisfying completion animation
• Streak tracking to build momentum
• View your history of completed tasks
• No account required — everything stays on your device
Crux is perfect for:
• Chronic over-planners who never finish their lists
• Anyone feeling overwhelmed by productivity apps
• People who want to build a daily accomplishment habit
• Minimalists who value simplicity
What Crux is NOT:
This is not a full task manager. There are no projects, tags, due dates, or integrations. If you need those, there are great apps for that.
Crux is for the one thing that moves the needle. The task you'd feel proud of completing. The thing that, if you did nothing else today, would make today a success.
Your data stays yours:
No account. No cloud sync. No tracking. Everything is stored locally on your device. We don't collect any personal information.
Start today.
What's the ONE thing you need to do today? Open Crux and commit to it.
