Can't get notes from spectrograph – Spectrum Analyzer RTA Review

I bought this to help transcribe music. But there is no tool for extracting notes from the spectrograph, so unless you manually convert frequency (Hz) to notes, which is laborious, it's useless. Spectrogram Pro does this for $2.99; I was hoping this would have some additional useful features, but really none of the modes but the spectrograph are useful for transcription.
