What This Does

Unifies **Samsung Health** CSV exports (7 active streams) and **aTimeLogger** SQLite (18 categories) into a single SQLite database (`lifetract.db`). AI agents query health and time data via JSON — sleep, heart rate, steps, stress, exercise, weight, and how you spend your hours.

Every record carries a [Denote ID](https://protesilaos.com/emacs/denote) (`YYYYMMDDTHHMMSS`), enabling cross-referencing with [denotecli](https://github.com/junghan0611/denotecli) on the same time axis.

Samsung Health and aTimeLogger are widely-used apps with standard export formats. **lifetract is a general-purpose tool** — anyone using these apps can use it. Data itself is private; public dataset is planned separately.

./run.sh update                     # Place new data + rebuild DB (one step)
lifetract today                     # Today's unified summary
lifetract read 2025-10-04           # Full day: health + time tracking
lifetract timeline --days 30        # 30-day cross-sectional view
lifetract time --days 30            # Time category analysis

Install

git clone https://github.com/junghan0611/lifetract.git
cd lifetract
./run.sh build    # → ~/.local/bin/lifetract

Requires Go 1.21+. Nix users: `nix build` (CGO_ENABLED=0 static binary).

Updating Data

Export Samsung Health + aTimeLogger backup from your phone into a date folder, then one command:

# Put exports in self-tracking-data/YYYYMMDD/, then:
./run.sh update

Automatically: moves Samsung Health folder → replaces aTimeLogger DB → rebuilds `lifetract.db`.
