A random high school band kid ,

Great but....

This app works great but just not the best for what I need it for. I’m in high school band and I’m trying to find a good tuner/metronome for free so I saw this and thought it just what I need but I found a couple things, keep I’m mind I could just be being horribly dumb but I couldn’t find any way to tell if it was in treble or bass clef, also for the sheet music it would be nice if there was more music just like the star spangled banner, service songs medley, etc. Not to be picky but the first point would be a good thing to know without having to use something else when ur tuning an instrument for the first time. Thanks, just wanted to get that out to people.

that nicknamee is takennnn ,

Good app, except for one thing

Soundcorset has a great tuner and metronome. I love how I’m able to customize the timing with triplets and sixteenth notes, something my original metronome never did. Another thing I love is how the app tracks my practice time, and I can see how my practice habits are doing compared to months ago, or even years ago. Plus, that helps me stay motivated to practice almost every day. The only issue I have with this app is that when tracking my practice time, the date is wrong. For example, today is Thursday April 23rd, and on my square of practice time for today it states that the date is Wednesday April 21st. I’m not sure if there’s a way to fix that, but if anyone knows, please let me know! Overall, I think Soundcorset is a good app to use and I would recommend it!

L'alto > Tout les autres ,

C'est très bon! Mais...

Below was my review, but now when I am using the app, tuner or metronome, the video thing shows up on my iPhone in iOS 9, and sometimes plays a long note and sometimes doesn't play anything, but it is really annoying because it interrupts my practice. It will also crash every 10 seconds (and I mean every 10 seconds). Could you please fix this? With it fixed, my review below is totally correct. And is anyone else having this problem?

I love the app. It has both a tuner and a metronome, so I only have to have one app. It's very accurate, and I tried out a lot of apps before this one. I like this one the best. It works for all instruments, even though when you go to tune there is a guitar symbol. I highly recommend it.

By the way, my nickname says "the viola > all the others." I clearly play viola. 😂
