"title": "Misleading App with No Sheet Music",
"body": "I purchased the app thinking that I would be getting a digital “Real Book”/sheet music situation for gigs. It is not that. It merely indexes music that you must upload into the app yourself. I spoke with a rep who informed me that they clearly tell you in ALL CAPS that they do not provide music. However, it is at the bottom of the page. They use misleading words in the intro like “FREE BONUS! Over 1300 Jazz Chord charts“, and “the ultimate pocket song reference”, which sells you on the idea, that you’re getting more of what you think you’re already getting. That’s all before you can get to the actual truth about the app at the bottom of the page... I was informed that I can’t get a refund because it’s through Apple, so I will leave $20 worth of wisdom here, IN CAPS: BE UPFRONT AND HONEST ABOUT WHO YOU ARE AND WHAT YOU’RE SELLING, ESPECIALLY IF YOU DON’T OFFER REFUNDS. Other than that, 5 star app, 2 star loss for the aforementioned issues.",
