Does it work with real radio audio, or in a noisy room?
Yes. It finds the tone and the speed on its own and copes with some background noise. Clean, steady signals read best. When a letter is uncertain, it's marked for you to check instead of being guessed silently.
Do I need an internet connection?
No. Listening, Write, Practice and Test all work offline. A connection is only needed to buy or restore Pro.
Is my microphone audio recorded or sent anywhere?
No. The microphone is on only while you're listening. Audio is decoded on your device as it arrives and is never recorded, stored or uploaded.
Can it write Korean Morse?
Yes. Type Hangul in Write and each syllable is split into jamo and sent with the Korean Morse table (SKATS). Double consonants and compound vowels are sent as their parts, so ㄲ becomes ㄱㄱ.
What does Pro unlock?
Standard and Advanced tests, unlimited decoding of audio files, longer recordings, every drill, and exports to M4A, ringtone and video. Live listening, Write, Practice and Starter tests stay free.
Is Pro a subscription?
No. Pro is a one-time purchase of $4.99, or the local equivalent in your store. There are no ads and no account. Restore it on a new device from Settings.
