Worked fine on iPhone 4. Upgraded to an iPhone 6 and crashes the moment I hit the listen button. Deleted and redownloaded.
Still crashes immediately on hitting the listen button.
I have over 40GB available on my phone using the latest iOS.
When it worked on my iPhone 4 I loved it for casual usage. Now cannot recommend. If it worked I would be happy.
