Info - Update: There is no App support - App has failed.
App now fails to open on latest iOS. Doorbell still works but that is it. Going to try on an old iPhone with an out-of-date iOS to see what happens. I have had mine now for nearly 2 years and have it installed on 3 iPhones. In the main it works fine. A bit heavy on battery use. Only problem that I have is in regard to the SD Card. It could be my fault and that I have installed a fake 32Gb card but when the recordings reach about 16Gb of storage the device reports that it is offline and tries to reconnect without success. The push notices work and live viewing still works, but no new recordings take place. Formatting the SD Card restores normal service.
