Train Morse code through quick drills, signal practice, and spy-themed Field Operations—now available as an evolving beta.
SpySignal turns Morse code practice into a set of focused training missions.
Start with guided lessons, then build speed and confidence through encoding, decoding, transmit, intercept, and practice drills. Each session is short enough for daily practice and structured enough to show where you are improving.
Features:
- Learn letters and numbers with visual dot-dash reference.
- Practice sending Morse with an on-screen transmitter.
- Decode signals by sight and by ear.
- Follow personalized practice recommendations based on weak letters.
- Keep separate local progress for multiple agents on one device.
- Opt in to a local daily training reminder.
- Preview cinematic Field Operations in beta; missions are still being refined.
SpySignal works offline. There are no accounts, ads, analytics SDKs, or cloud sync.
