Solstice

A calm, local-first daily planner for people who think in days.

Notes and tasks organized by day, not by folder. Your work happens in days. Solstice keeps it that way.

What's inside

Built around the day, not the database.

A month at a glance

Square date cards in a quiet month grid. Scan a week without losing your place. No counters, no streaks, no noise — just your days.

Projects rail you can collapse

Group days by project on the left rail. Filter when you need focus, hide it when you don't. The planner stays the star.

Local PIN, local files

A static PIN unlocks the app. Everything lives in a single local folder you control. No accounts, no servers, no sync — unless you point your own Dropbox or iCloud at it.

Drop in any file

Attach references, screenshots, PDFs to the day they belong to. Preview them inline without leaving the planner.

Questions

The short answers.

What does “local-first” actually mean here?

Your notes and tasks live in a single folder on your own machine. No cloud account, no syncing service in the loop. Back it up the way you back up everything else — Time Machine, Dropbox, iCloud, a git repo, anything.

Which platforms does Solstice run on?

macOS, Windows, and Linux. Same app, same data format on all three. Download the build for your OS from the GitHub release.

Is it free?

Yes. The desktop app is MIT-licensed and free to use. A paid tier with optional extras may arrive later — the core daily planner stays free.

How is this different from Notion, Obsidian, or Apple Notes?

Those are flexible canvases organized by folders or databases. Solstice organizes by days first. Open the app and you see this week, not a list of pages. If your work has a natural daily rhythm, that change in orientation is the whole point.

Can I export my data?

It’s already exported. Notes and tasks are plain files in a folder you own. Open them in any editor. Move them anywhere. Delete the app and your data stays where it is.

Does it sync between devices?

Solstice itself doesn’t sync. Point its data folder at your existing sync provider (Dropbox, iCloud Drive, Syncthing) and your days follow you. We keep that integration external on purpose — you choose what touches your files.
