IPHONE 6/6+/future iOS software CRASH

This is hands down the best quick easy to open piano app. The sound is perfect, the tone, timbre and weight of each note is perfect. I always used this app for quick note reference and tuning vocals and guitars. AND I always use the app to play along with songs in my music library. It helped with finding keys of songs so easy. Please make it compatible!!! It freezes when the screen tells me that theres an updated app in the App Store but theres not!!! PLEASE FIX :(((((
