The Total Connect Comfort Intl app developed by Resideo Technologies is a free lifestyle app available for the iPhone platform. This app allows users to remotely monitor and manage their heating and security system anytime and from anywhere. It is compatible with the evohome thermostat systems, single zone thermostat, European voice-controlled thermostat, Wi-Fi Smart thermostat (in selected countries), Evohome Security, and Sucrebox Security. Users can view and set the indoor temperature, change the program time period, and set a quick action (on selected solutions). The app allows users to access multiple locations if more than one system is registered, view a 5-day weather forecast, use the demo mode before purchasing a thermostat and turn on or off email notifications about the system's connectivity status.

With the Total Connect Comfort app together with an Evohome or SucreBox security system, users can arm, disarm, or partially arm their security system, take camera shots upon an automatic or manual alarm trigger, receive alarm notifications via email or SMS, and view the alarm system activity feed. The app automatically upgrades to new features once they become available.
