Does what it says on the box

Solid app, straightforward and easy to use. Getting results in real time is a plus.
Hopefully in the future, the developer will include an option for a browser selector on the iPhone app, instead of just what's currently baked in.

Excellent application

This is exactly what you’d want an iPhone curl app to be. GREAT job. thanks

Maybe consider a dark mode or the ability to change themes?
