DayFinish time
Add up what's left, drop it into the hours you actually work, and you get the time today runs out. When the work outgrows the day the readout turns red at 9am, not at 6pm, and the list is still yours to cut.
A text file is the whole database
The day planner that wires itself into your agents.
todos.md and memory.md are the whole
database. Daymetric tells you what fits today and when you're
done. Claude, Cursor and Codex read and write the same files, and
anything they think of on their own arrives as a proposal you
approve. Your folder stays yours.

Today
one windowOne window, and it already knows when you're done.
Every reading on the board comes from two markdown files. Keep scrolling and the board says what each one is.
- 01 · Done by When today's remaining work runs out, not a guess. It moves as you clear things.
- 02 · The day note One sentence a day, derived from the files and nothing else.
- 03 · From Claude A proposal waits for your ACCEPT. Nothing reaches the day unseen.
- 04 · Effort on every line Thirty minutes here, an hour there. It is what makes a finish time possible.
Your agents
21 toolsIt finds your agents and wires itself in, so you don't have to.
Daymetric ships its own MCP server, native Swift, no Node, nothing to paste into a config file. Say yes once and every agent it finds on your Mac gets the same 21 tools, plus a page of instructions on how to behave inside somebody's day.
One yes at first launch. One switch in Settings takes it out again, and moving the app never breaks it.

It arrives already knowing the house rules: proposals, not surprises; always set an effort; defer, don't delete. Six thousand characters of instructions ship inside the app and are re-read every time an agent connects.

The loop
done.md → memory.mdEvery task you close teaches the next estimate.
The log keeps the time you finished. When a project keeps running
long, memory.md gets a multiplier, and the finish time
uses it before you would have. Your agent reads
learned.md before it re-proposes a workstream, so a
dead end found once stays found.

Calibration
Guess 30m on a project you reliably spend an hour on and the estimate is multiplied before it reaches the clock. The briefing can say so out loud: “Atlas has run 1.4x your estimates for six weeks.”
The day note
One plain sentence a day, derived from the files and nothing else: “You've moved ‘Call the accountant back’ 6 times.” Four is usually the app telling you something.
Your day
05:00 → 22:00The lamp beside the date knows what time it is.
Coffee at seven, noodles at noon, a moon after dinner. Sixteen pixels a side, drawn with code and baked into the app, and the one place the panel is allowed a colour that isn't the burn. Each one plays its entrance once and then holds still. A lamp, not a screensaver.
The menubar carries the same finish time all day, so the window can stay closed. On the phone the same files are the deck you carry: swipe right to clear, swipe left to defer.
Your tasks
todos.mdA task is one line of text. That's the whole format.
No database, no export button, no proprietary format. Open the file in any editor and the app follows along as you type.

Your files
no lock-inNobody can revoke a text file.
Everything Daymetric reads and writes is plain markdown in a folder you already control.
Durable
Opens in TextEdit today. Opens in TextEdit in ten years.
Private
No analytics, no tracker, no crash SDK. The scheduler never asks the network to plan your day.
Independent
If Daymetric disappeared tomorrow, your day wouldn't.
Your account carries the same files to your phone. Nothing about the format changes on the way, and the folder auto-commits to a local git repo, so last week is one command away.
Your plan
one priceFourteen days, everything on. Then £6 a month.
No free tier and nothing held back during the trial. A crippled trial tells you nothing about the app. When the fourteen days end, Daymetric becomes a reader: it still opens, still shows your day and your log, and still exports everything. It just stops writing until you subscribe.
