Well firstly good day 
. i would love share an idea for an app which i had in mind for a couple of years now. If it could be made on thunkable then wonderful if not then ;( . It goes like this :
An app - where in there would be 2 phones involved, where one phone will be used as a display/ receiver while the other the controller.(talking about a ble connection). the controller should be able to like change the display to pictures or self-colors etc (even play videos if it can) but it should be displayed to the other phone. This is to help small time photographers manage multiple phones and set them up around the place. Even would be a crazy halloween decoration if u stick it up ur shirt and have a video of moving eyes or so if so plz get back to me soon would appreciate the help.
