Yes, the majority of settings are saved on your iHome product. Mode, Volume, Lighting Modes, Alarms, etc. are all saved on the iHome unit and will be there even if the app is not present. Please note that any changes on the iHome product can change these settings (in other words, if you set an alarm using iHome Enhance and then change the alarm using buttons on the iHome product, the changes will override the settings made by the app).
