Why no more updates

Why. I updates for the latest iOS, and no functioning of jPlayer.

I like it

The interface could be a little easier to use but it has most of what you need IF what you’re searching for is what notes/chords are in a particular key/scale. The layout is sort of like the circle of fifths, which makes it both intuitive and clunky at the same time. Although you can easily see what notes/chords are present in a minor key, it presents them in the form of the relative major key so you have to understand a little about relative major/minor keys and the interface to get used to this.
No problems with crashing or anything like that. Seems pretty stable and fast.

2.2 stars for a reason...

read a couple of reviews here that mentioned that the app closes when you swipe to the tuner...and indeed it does.

so much potential, but as is the case with most of these up and coming developers, they miss the mark. I’m a new guitar player willing to spend reasonable money on tools to help me along my journey, and this could have been one of them. but instead of being mad about your disregard for quality, I guess I really should thank you for keeping me from spending $5 on an app that I surely would regret purchasing later on. yea, thanks for not overachieving and saving me money. I like that.
