first off, it took me FOREVER to actually sign in. i had to try 5 times to get the sms to work, and that's wild. one or two is fine but 5 tries is kinda... anyways, i like the tuning, it's simple but sometimes it's annoying getting the pronunciations right.
here's a couple suggestions i have personally:
-having different singing types. some examples are screaming/yelling, or talking. talking would make it easier to create raps (not only for singing too, it would be fun making conversations with characters), and screaming/yelling would make it a lot more fun to create covers of rock songs. this could be placed under the EMOTION category, because currently the only thing added to emotion is singing volume.
-be able to directly duplicate projects. i wanted to create the chorus lyrics in a seperate project but when i tried to duplicate it, there was no option.
-be able to have a guest account. if somebody wants to try PocketSinger out, they can make a guest account. their projects probably wont be able to save though, so a warning would be very helpful.
overall, PocketSinger have great potential, but since it's so new it's bound to be overly simple with options.
