Make diary page stick on mobile App?

All day long I log my calories as I consume them, each time I open the app it bounces me back to the useless "Dashboard" and I then have to click back to the diary. This is frustrating and time consuming, in addition the app is sluggish and there is a notable delay waiting for it to switch back and forth. I have complained to developers many times and only get back a robotic reply. Seems this app could use a decent update considering how much we are now paying for what used to be free and used to work a lot better than current buggy app. :#
