Hesperus is a free, easy-to-use and customizable HomeKit app for iPhone
Early adopters of Apple’s HomeKit home automation framework tend to notice one thing early on: there’s no real UI beyond Siri. HomeKit helps bridge functionality between various smart home accessories which tend to each have their own connected apps using Siri, but Apple hasn’t released a Home app in the same way it made Health for HealthKit.
Instead, users rely on a folder full of third-party apps from accessory makers, some of which are better than others, or a highly functional but somewhat pricey third-party app called Home to give HomeKit the UI it needs. Today there’s a new app on the market called Hesperus, which is free to use and has a friendly, customizable interface.
