"title": "No updates since 2012",
"body": "Hey, so don't get me wrong, this app is really great, and it's awesome that's it's free! I just wish there has been some updates in the past 2 years! Clearly this app has probably been abandoned by the developer, which is a shame, because it could have even more potential than it already does! For example, it would be nice to have the options under \"free training\" consolidated on the actual training screen itself... so one would not have to switch between screens multiple times to set it up. Most importantly, however, I would love to see an option for the BPM to go lower than 140! Not everyone is a vocal gymnast from the start, and some of us (just me?) still have some issues with pitch that we'd really love to dial in at a more comfortable pace, especially when dealing with our lower range. Overall, however, a great aid to singers. Crossing my fingers that the developer will come back sometime! Otherwise I might have to make my own app ;)",

"body": "I've been using this app to warm up my voice for about a week now and have loved the results! I can't believe those excersises really help my vibrato. However, lately I've been experiencing problems with the sound. Sometimes it just goes completely mute and I either have to delete and re install it or restart my phone. Recently, none of that worked. It's not my phones general audio. The creator should fix the bugs? Updates?",

Lots of other tools too, like a piano, recorder and even a personal trainer (haven't used that aspect of it yet, but nice to see it there!) I definitely recommend this to people looking for a warm up app.",
