Skywave: RF Field Kit

iOS app by Shadowfetch · App Store ID 6792598504 · iOS

Skywave is a complete amateur-radio and RF reference that runs entirely on your device. Every lookup and every calculation happens locally — so the whole shack works on a summit, in a basement, on a plane, or anywhere the signal drops. No account. No subscription. No cloud round-trips. Nothing you enter ever leaves your iPhone or iPad.

Built for licensed hams, shortwave listeners, preppers, and anyone who wants serious RF tools without ads or logins.
