How a day is kept
Name your stars
Decide what a good day is made of. A run before breakfast, an hour of real work, a call home. Give each one a name. These are your blocks, and you can rename or reorder them whenever your life changes shape.
Log the evening in thirty seconds
When the day is nearly over, tap the blocks that happened and add a line if you feel like it. The day meter fills. That is the whole ritual. Most habit trackers want more from you. This one wants less.
Watch the constellation grow
The year plate shows each recorded day as a point of light, with your streak as the line running through them. Miss a night and the gap simply shows, so you see the true shape of your months instead of a tidy story about them.
The diary and the archive
Some days want a paragraph.
Beside the log sits a journal. Write in Markdown, tag what you like, and it saves while you type. The diary lives in the same archive as your blocks, so a week of notes and a week of ticks read as one record.
Scroll back through History and the year lays itself out like a chart room: days, marks, the streak, and the odd note in the margin.
One reminder, at dusk
One email at dusk, in your own time zone.
No streak-rescue banners. No buzzing at noon. At the evening hour you choose, a short note asks what the day held. Answer it or ignore it. Switch it off in Settings if you would rather remember on your own.
A reader who has only ever read you.
Ask for a summary of the day, a review of the week, or the answer to a question about your own entries. The assistant reads what you wrote and hands it back shorter. It can suggest tags. It cannot invent a day you never lived.
Questions
- Is Ephemeris a to-do list or a habit tracker?
- A little of each, kept small. You plan a day by naming its blocks, then record which ones actually happened. The planning is the to-do list part. The record and the streak are the habit tracker part. The diary is the part most apps leave out.
- How long does a daily entry take?
- About thirty seconds. Tap the blocks that happened, write a line if you want one, done. Longer thoughts go in the diary whenever you have them.
- Does it remind me?
- Once a day, by email, at the evening hour you pick in your own time zone. You can switch it off in Settings.
- Is it free?
- Yes. It runs in any browser on a phone or a desktop, and you need only an email address to begin.
- What does the AI do?
- It reads your own entries and gives back a short summary of a day, a review of a week, or an answer to a question about your record. It never sees anything you did not write yourself.
