First I think Blynk is great. I have several projects running and 3 more in the queue. My desire at this point is to learn/experience working with a local server (two actually - Raspberry Pi and Windows versions). The ones I currently have I want to keep in the Blynk-Cloud for now - but a couple new ones I want to start playing with on a Local Server.
My Challenge is that I am working with an iPhone and I am a bit stumped as to a viable method to get access to multiple servers. If I have read everything correctly - an instance of Blynk App can only be tied to a single server and any/all projects created under that app are tied to that server via their authorization code.
So this would require having multiple instances of the Blynk App with each linked to a desired server (cloud or local). And the projects under that instance would be tied to that server.
This is my current understanding. So I have been in search of a method to get 2 or more copies of the Blynk App on my iPhone - and to date - none have been successful. All of the cloning programs seem to be social media focused - and jailbreaking seems very hit-and-miss especially with there latest iOS versions.
There is potential of modifying the BundleIdentifier - but most procedures seem to be Mac centric (i am a windows guy). And seems it needs an IPA version of the App - and that is getting beyond my knowledge base.
So asking if anyone has a workable solution / procedure. And “no” i dont want to move to an Android - my entire family is iphone-facebook centered 
Thanks
