FeedpointAmateur radio station notebook for iPhone and Android
Measure, cut, log. No signal needed.
Feedpoint works out antennas, feedline, band rights and RF exposure for your own station and licence class, and keeps a field log with ADIF export. It all runs on the phone: no account, no subscription, no network.

Four reasons to carry it
Trim from measurement
Type the resonance your analyzer shows. Feedpoint says how much to cut from each leg, learns this wire's real end effect, and uses it when you cut the next band.
Can I transmit here?
Frequency, mode and power against the rules for your country and class: US, Canada, UK and Germany. Every answer names its clause and the date the rules were checked.
RF exposure record
Minimum distances by the FCC method (OET-65), the German BNetzA method or the UK ICNIRP 2020 levels, saved with the date, the inputs and the sources, and shared as a PDF.
A field kit that works offline
Battery budget for your radio and mode, a one-hand log with a big UTC clock and a dupe check, ADIF 3.1.8 export, one file per park, and spot text ready to send by SMS.
Screens
The store screenshots arrive with the release. These are the four screens they will show.

Nothing leaves your phone
No account, no sign-in, no analytics, no ads. The app asks for no permissions and makes no network calls; the only exception is the store when you buy Pro. Your stations, antennas, records and logs are one file on your phone that you can back up yourself.
Why we built it
The antenna and band plan apps hams use most have not been updated in years, the loggers sell a sync subscription, and outside English there is almost nothing. Feedpoint puts the sums you do on paper into one offline app, with the formula and the source under every result.
