crowfly is a single-html-file golf round GPS tracker.

Hit your shot, tap "log shot", walk to your ball, repeat. Shots and rounds are stored in localStorage. Distance markers. CSV export. Zero account, zero backend.

Short-term roadmap:

- Mandatory login

- AI club recommendation

- Paywall everything

- ERC-20 issuance

- MCP servers

- Even darker mode

Long-term roadmap:

- Humanoid agent plays the round for you

- Configurable celestial body (Moon, Mars, Titan etc)

- Round summary as a podcast

- Rewrite in Rust
