Altum

Altum

A minimalist deep work companion for the terminal. Altum times your focused work sessions, walks you through a short review when you stop, and keeps everything in a local SQLite database so you can see how your deep work adds up over time.

The name comes from the Latin altum, "deep".

How it works

1. altum start opens a full-screen timer. Work until you're done, then press Enter to stop.
2. A four-step review captures the session: the milestone you reached, focus quality (1–5), any interruptions, and a short reflection. Only the milestone is required.
3. The session is saved to a local SQLite database.
4. altum report summarises your recent sessions: total deep work time, average session length, average focus rating, best day, and more.

Data and configuration

Sessions are stored in a single SQLite database. By default:

~/.local/share/altum/altum.db   # $XDG_DATA_HOME is respected if set

The location can be overridden with the --db_path flag, or persistently:

altum config set db_path /path/to/altum.db

Configuration lives at ~/.config/altum/config.yaml. A different config file can be passed with --config.

Development

go build -o altum ./cmd/altum
go vet ./...

Built with Bubble Tea, Cobra, and a pure-Go SQLite driver (no CGO required).
