The timing of the actual AeroPress bit I actually have pretty much down to a fine art, it's the knowing how long to leave my kettle off the boil that I keep misestimating. It would also be nice to have a coffee bean grinder timer.

Great app thanks.

What temprature should the water be? I can never remember this and wish the app had a general information section.

It really is a great app, I've used it everyday since it's release so far.
