Product philosophy

A few dependable tools, like a good Leatherman. Not 200 mediocre ones.

Built for the field

POTA activations, Field Day, contest pileups, EmComm deployments. Designed for when you're operating, not planning.

Offline-first

GPS-derived features work with no signal. Propagation data is cached with a last-updated timestamp, so you always know how fresh it is. Never stranded.

No friction

No account, no onboarding, no ads. Open the app, get your answer.

Built by K7BPM, an active operator who got tired of juggling five apps in the field.
