Needs a lot of improvement

My first experience playing with my new hue lights setup. App freezes and crashes my iPhone 6 Plus a lot. Tapping the beats per minute to get things going faster is ridiculous. Severe lag when performing button presses and starting and stopping. Has the potential to be great. Paid $2.99 for this app. Not quite worth it. Please fix this app.
