Bad first impression – Tone - Learn Perfect Pitch! Review

I haven’t started it yet. I thought this was a free app that I could upgrade to a pro version if things go well. In the first two minutes, I had to give a fake email address into a so-called “optional” text field to proceed. Immediately after that I find out it actually costs over $100 per year. Sort of puts me off and I’m toying with writing an app of my own to teach myself to identify notes by hearing.
