Built by someone with ADHD who was tired of planning impossible days.
You're not failing. Your plan is.
Every morning you plan an ambitious day. Every evening you feel like a failure. But here's the truth: You're trying to fit 12 hours of work into 8 hours of time. No one could succeed at that.
"I'll definitely finish all 15 tasks today"
(You won't. That's 10 hours of work.)
"This will only take 30 minutes"
(It takes 2 hours. Every time.)
"Why am I always behind?"
(You're not behind. You're overcommitted.)
"Tomorrow I'll catch up"
(Tomorrow has even more tasks.)
Finally see the truth before you start
Block-Level Warnings

Works With Your Calendar
Integrates with Google Calendar. See your meetings AND your tasks. Know your real available time.
Built for ADHD
Clean, calm, obvious. No overwhelming features. No decision paralysis. Just clarity about what's actually possible.
