The perfect-day home for builders
Design the day you keep promising yourself.
Zendar turns your ideal day into the plan you live against - blocks to keep, budgets to spend, and a grid that only ever adds.

by design
- Morning run: designed 06:30 to 07:30; lived 06:50 to 07:35.
- Deep work: designed 09:00 to 12:00; lived 09:40 to 11:55.
- Ship one visible thing: designed 13:00 to 15:30; lived 13:05 to 15:30.
- Admin sweep: designed 15:45 to 16:45; skipped, tagged as legitimate life, not counted against the rings.
- Read the hard paper: designed 17:00 to 18:00; lived 17:20 to 18:05.
- Budgeted slack: designed 21:00 to 22:30; lived 21:00 to 22:30, 50 minutes over budget.
Instruments
Three instruments. One honest loop.
Today, as a shape
Blocks with a now-line - not a task inbox. Mark done in one tap; the day closes quietly.
Rings, both directions
Floors fill toward a promise. Budgets spend toward a limit. Same instrument, flipped.
A grid that only adds
Every active day lands a square. Color is what you did; intensity is how much.
Method
A mirror, never a cop.
When a block slips, Zendar asks one question and takes “life happened” for an answer. Legitimate life never counts against your rings. Streaks carry freezes. Active days can’t be broken at all.
- One question, four chips. Honesty in two taps, never a form.
- Counters only rise. Lifetime hours and active days never decrement - a bad Tuesday can’t erase March.
- Raising a promise is instant. Lowering one waits for Monday. Targets window-lock, with friction in exactly one direction.
What pulled you away?
The gap between planned and lived is the most useful data you own. Zendar is where you finally see it.
Distribution of proof
Build in public. Honestly.

No free tier. On purpose.
A commitment device shouldn't be free to ignore. One plan, everything included - the daily home, template, targets, grid, projects, public profile, PWA and weekly recap.

FAQ
Fair questions.
Is Zendar a calendar?
No. Calendars record obligations to other people. Zendar holds the day-shape you want, instantiates it each morning, and measures the gap between designed and lived.
Does it block apps or shame missed blocks?
Never. A missed block triggers one gentle question. “Life happened” is a complete answer and doesn't touch your rings.
What's public?
Nothing, until you explicitly publish a grid profile - and then only the counters you pick. Private by default, forever.
Why is there no free plan?
Zendar is a commitment device; $12/mo is part of the mechanism. Beta comps exist - ask.
Do I need the app open all day?
No. Mark blocks done when they happen or backfill in seconds. The installable PWA sends optional block-start nudges.
