Love the interface and capabilities buuuut No timing info the entire reason I m looking for a curl based app I would be willing to pay for an app that both lets me customize headers AND get timing info but apparently nothing exists yet Maybe next release                 Doesn t have timing info FisterDotOrg

Simple easy to use and exactly what I needed Would be nice to have some type of JSON key value input for post bodies                 Fantastic RJ Hirsch

Awesome app I have one feature request I don t know if it is possible but it would be nice if you could select whether or not you want iCurl to use your wifi connection or not Basically I don t want to go into my iPhones settings to turn off wifi when I want to force it to go over the carrier network outside of my home or office network Thanks                 Sweet One feature request gmreston
