Let me give you an example.
Let's just say I want to explain how to turn on Personal hotspots for the first time. I take a screenshot and I want to draw a circle around it. To do that, I would have to open my picture editing app, draw the circle, open Tapatalk again and select the latter picture. That's one too many actions for just a simple task.
In the editing option build in Tapatalk pro, i don't have to go through all that hassle.
I just have to take the screenshot,
View attachment 74120
Select the photos tab
View attachment 74121
Select the drawing tab in the next screen
View attachment 74122
Draw the line
View attachment 74125
Tap the apply and then the done button
View attachment 74127
And I'm done, without even having to leave the Tapatalk Pro app
