The IC5 app allows you control your house’s temperature to a comfortable level without having to be near the heat pump. Scheduled temperature control allows you to set the temperature of the house at some time in the future. For example, if you plan a stay in your vacation house, you can set the start and end temperature in advance. You can then enjoy the stay in the house without wondering about your heat pump’s settings. The IC5 app has a build-in safety feature, where you will receive an SMS if the temperature or humidity in the house exceeds the allowed limits. In case of fire or flooding in the house, you will then be notified. If you have more than one heat pump, it is possible to them all from the same app. The IC5 app communicates directly with the heat pumps GSM Unit. In Setup of the GSM Unit, you can choose between SMS and GPRS communication. Profort recommends you install a SIM card in your heat pump for GPRS to allow more control features in the app such as a log of the house’s temperature settings and scheduled temperature control. You can always swop between SMS and GPRS communication in the house’s Settings. The Profort GSM Unit is a 100% Danish developed product by PROFORT Engineering.

Verdict
The clearest difference is in-app purchases: IC5 at none against Impact!'s 1. IC5 also leads on iOS requirement (8.0 vs 26.0). Impact!'s advantage is update cadence (fortnightly vs every 3 months). On price, ads and device support there is nothing between them.
