Are there any mobile apps for HEAT Cloud?
There is an iOS App in the Apple App Store for iPhone and iPad; search for "HEAT Service Management".
Android is being supported via the mobile browser.
Additional functionality and better support for smaller resolution devices such as phones will be coming in future releases over time.
Long term, both iOS and Android will move to the browser based version.
If you need a native application for the Windows Mobile OS please open an Incident with Support requesting to be linked to Enhancement Request RM 229939.
