I also hate obligatory mobile apps, especially when they’re linked to hardware: At the battery company I work for - pilaenergy - we’re aware that our hardware may well outlive our software, so we’re providing a mobile app that’s accessible over an WiFi access point or over your local WiFi, as well as the traditional mobile apps. This way - the software comes bundled with the hardware and can’t be sunset. Something that has long been an issue with IoT products.
