SP2ALERT

SP2ALERT is an alert app for amateur radio operators that delivers real-time push notifications for new POTA (Parks on the Air) and SOTA (Summits on the Air) spots.

■ POTA / SOTA Spot Alerts Automatically detects new spots and sends push notifications — even when the app is in the background.

■ Three Alert Modes (foreground only) • CW Vibration — vibrates in Morse code pattern (adjustable WPM and amplitude) • CW Tone — plays Morse code through the speaker (300–1500 Hz pitch) • Voice — reads spot information aloud (phonetic alphabet supported)

■ Flexible Filtering • Filter by band and mode (all bands from 160m to 13cm supported) • Filter by POTA program (JP, K, VK, etc.) or SOTA association • Include/exclude specific callsigns, park references, or summit references • Save and switch between multiple named presets

■ Hunt / Chase Management • Import POTA Hunt and SOTA Chase history via CSV • Alert only for unworked parks and summits • Multi-location activations (same operator at multiple parks) are always alerted even if one park is already hunted

■ Notification Controls • Configurable polling interval • Alert time window (e.g. 7:00–22:59 only) • Re-alert interval • Alert expiry timer • Additional alert on frequency/mode change

■ English / Japanese Localization The UI automatically switches between English and Japanese based on your device language setting.

【iOS Limitations】 Background operation is limited to notification banners and sounds. CW tone, voice, and vibration alerts only work while the app is in the foreground. Background polling timing is controlled by iOS and may be delayed beyond the configured interval.
