There appear to be two apps for IOS for Evohome Heating & Security. One is the original one which has a thermometer and a padlock as icons on it and the other simply a capital “H” and calls itself “Home/Total Connect”. The former takes me to the usual app, the latter to the web page. I must have downloaded the latter from somewhere at some time but it does not appear in Apple’s App Store. No complaints, it does save me having to access via Safari!
