Data

data/phones.json is the single source of truth, shared by the CLI and the web app — tests/test_sync.py fails if the two copies drift apart. Each entry records the release year, whether the phone supports MagSafe, compatible case types, screen protector type, and a link to a full buying guide.

Dimensions are not yet populated for every model (dimensionsVerified: false). The UI hides the dimensions row when the value is absent rather than guessing.

Development

python -m pytest tests/ -q     # run the test suite
python -m build --wheel        # build a wheel
