Just dowloaded it, looks awesome! Definately make it easier to enter the ODO reading. Now to do the same with the other entries and bye bye keyboard
One suggestion if I may, on the bottom where the tabs are, it might be easier to navigate through the different tabs if the left arrow was to the left of the tabs, rather than having both arrows on the right. Not sure how hard that would be, but just a suggestion
Keep up the good work!
