Question: If you are creating an application (app) to be used on a smartphone or tablet, do you have to verify and list all the devices that the app works on?

Answer: No. For an app, it is not required that the vendor verify every single device the app will work on, but the registration must include the entire platform (i.e., Android or iPhone). The device that allows connection to the electronic control module (ECM), the phone/tablet OS with version range, and the app together can be certified.

If the electronic logging device (ELD) only works on certain models, the provider will need to specify (e.g., a 64-bit iPhone model with iOS 7 and above). 

Note: There should be separate registrations for each platform (i.e., “ELD for Apple” and “ELD for Android” would be registered separately).
