Enjoying learning

I have some music background but have never picked up a violin until I started with Tonestro. I like to learn with accuracy, and the app picks up easily whether the tones I play are too low or too high so that I'm practicing in tune with the proper finger positions. It’s never boring as there are so many melodies and songs to play with or without accompaniment, as well as options to slow or increase the pace of each piece of music. Reached out with a question at one point and promptly received a response. Best music program online that I’ve ever used!

Good, but needs improvement

I’ve been playing for awhile and I can say I have improved with this app. The biggest issues I’ve been having is when playing for score in lessons, the music stopping to wait for you to play right on time is unrealistic and robotic, and does not help with improvement. I either have to play the string early to avoid this or just live with it stopping every note. Both make the music sound horrible. I play much better with the listening option. If there was a way to turn this off and have the music play without stopping to wait it would be great. My second issue is not having a way to turn off the letters in the notes. It’s not helpful after awhile and inhibits memorization. I would rate five but these two issues are just too prevalent to ignore and interfere with the primary function of the app, which is to educate effectively in playing violin.

Developer Response ,

I don’t think it’s good enough for me to pay money

I know you have to make money somehow and I don’t have anything against it, but I can’t get premium because my family won’t let me in all I wanna do is play the violin I wanted to since I was four when I got my violin but I wasn’t able to but I guess I’ll just have to wait until something else comes out Thank you for your time.

Developer Response ,

Hi, our musicians and software specialists are working full-time to provide a high quality learning opportunity to support others who don't have access to in-person lessons. With Premium you can learn with many video tutorials, exercises & songs. Without the premium option we wouldn’t be able to maintain and improve the app anymore.
