Unfortunately I found out the hard way that this app does not work on I-Phone 6. I paid for the full app and opened it up only to discover that theres absolutely no sound. It doesnt matter how many times you press the apps sound and/or volume button. I hear all my other apps perfectly so its not a problem with my I-Phone. An update is needed on the app to make it compatible with the I-Phone 6. Guess Ill have learn Bulgarian elsewhere.
