Time-blocking, the healthy way

More done.
More rest.
No trade-off.

Time Stacker plans your day by stacking real durations onto a 24-hour clock. Whatever you don't fill becomes sleep — so you instantly see whether today actually leaves room to rest.

Built for people with no time to spare

Sleep is never an afterthought

Whatever you don't fill becomes rest — shown in green. If you've over-packed the day, you'll know before you live it.

Phone and laptop, in sync

Plan on your phone at night, run your day from the laptop. Same boards, same journals, no difference.

How stacking works

Three steps. That's the whole idea.

Add what your day needs

Work, gym, meals, focus time — add each as a duration. Two hours here, forty minutes there.

Watch it stack

Each block stacks onto the clock in order. The ring fills up as you go — color by color.

The rest becomes sleep

Whatever's left at the end of 24 hours is your rest. Green and clear, so balance is never a guess.

Everything you need to run the day

Planning, tracking, and the project tools to actually get things done.

Doing more shouldn't cost you sleep
