Let me try to understand what you are writing. Your app and device is on the market (#1 above) . Now you are trying to get approval for an additional app that interfaces with a similar device marketed by a different company (#2 above where with our own should be with their own). And the additional app has now been rejected under the guideline 4.3. Is that correct?You have two avenues forward -1) create a separate developer account under your clients name and submit the additional app under that account. Be sure that the additional app is really different from the user's perspective.2) (better IMHO) update your current app so that it is a generic app that can be used by either your device or your client's device (or future clients). Under that generic app create two branded options that the user selects. Advertise your device (and have your client advertise their device) as using the well-known generic controller for photo frames.
