Easy KNX is an application that allows you to manage quickly and easily an entire KNX installation. No extra hardware required only a KNX gateway. To be able to use this application, it is necessary to have a configured and working KNX installation, which must have an interface with the IP network (KNX/IP Gateway). The first time you open the application, it will be blank, that is, it will not have any floor, room or control created. You will need to create these elements according to the complexity of your KNX network. As you create each of the controls you can test them immediately.

Verdict
The clearest difference is price: HMI at Free against Easy KNX's $24.99. HMI also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (11.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
