This looks like exactly what I need, but the interface has four buttons all marked in what appears to my ignorant view as Chinese. Apologies if it is not Chinese. It would not need translated buttons, but just a more intuative layout to use. One opened an email, one complained that it could not model what I put (nothing) and I suppose youa re to enter data freeform? but there is a nice grid in the screen shot.

This app is hard to work with. The interface needs to redesign by allowing for multi-language. Based the tech information working language English which is misleading it’s actual Traditional Chinese.
