No, as in no i don't want to use anything other than the grand exchange inside the game.
I agree with this. If such a thing became available it should be an in-game feature to use by everyone or not at all.
Unfortunately, Jagex would probably never add such features as it would be promoting flipping in their eyes. Once one gets the hang of it, flipping is a very powerful, and slightly easy method to make money. This app is only intended to make things even easier.
It would be about the same as if Jagex added an in-game tool to track gambling profits (but of course, flipping is no where near as controversial as those gambling games).
Yes please. Great concept!
I appreciate your feedback
Things are going great and I just got another major feature working (which, unfortunately, introduced new bugs that I now have to fix).
