The Supra eKEY app succeeds magnificently in one area: making you look incredibly unprofessional. I can get over the UI being ugly; fine, its just a tool to open doors. Whats entirely unacceptable is the app refusing to communicate with lock boxes until you hard reset your iPhone. This has been a consistent problem with the eKEY app and is not being fixed. Time is valuable in the real estate industry, I prefer not to waste it paying for a terrible product that doesnt work. iPhone 7, latest iOS release.
