To use ionic view app

Please any developer out there send me an invitation code .

What do you need an invitation code for? Everyone can download the Ionic View app from the stores and use it with their apps freely.

in order to start testing, its asking i need an invite from any developer to test test one of their apps

If you sign in into the app you can view your own apps. However if you don’t want to sign in for some reason, you can get your own app’s invite link in the Ionic Pro Dasboard
