Call-O The calling app

Hi all !! Hope you are all having a great day ! This is my app Call-O (I am still working on the name) With this app you can make phone calls to anyone in your contacts. You can also do group video calls and add members by sharing invites.

oh very sorry, i will just fix it

Now check it

you are not even asking for permission ? are you? for me its saying permission is denied pls change it from app settings not everyone will go to change it okay? ask permission on initialize.


So, you want the app not to ask for permition right ?

no i meant to ask

Replied you in the PM, now i wish that you delete this message as its off topic.

Yes you heard it right, added some features and some bug fixes. Added permission as @Aarush_Kumar said. Have fun !

If you encounter any problems in the app, kindly PM me, as I am new to MIT APP INVENTOR, so I can make mistakes. @Aarush_Kumar pls try it out and tell me if it fixed the thing you said.
