Countdown Timer Button vs HAMSignal

This app is designed to be used as a board game turn timer, but it can be used anywhere where there is need to display countdown in seconds. Fully customizable colors and user can define how remaining time is displayed.

Get an alert when your HF band is likely open at your QTH. HAMSignal rates each band, day and night, from live NOAA solar data. Made for licensed amateur radio operators. ALERTS • Band alerts (80m to 10m) follow the solar forecast by default: SFI and K-index, day and night, with thresholds you can adjust. • Or choose measured: it counts stations that receivers near you decode on PSK Reporter, so it needs active receivers in your area. • Four free space-weather alerts (M-class flares and up, G1 storms and up, strong aurora, proton events), plus custom alerts on SFI, K, solar wind, X-ray and more • Background checks run when iOS allows, so an alert can arrive late.
