Phone Application

Would be useful if you could develop a real iPhone/Android supported App. Putting the link on the home screen as currently is ok but does not offer the same flexibility as an App. The problem with the current link is that it throws you out every time and you need to re-log - even when ticking ‘keep me logged in’. Also does not allow to save settings such as a 6 day work week, which each time needs to be reset. I believe a properly developed App would help in this regard and be very useful for us in smaller practises that are on the road quite a bit as well.
Thanks!
