EzyTip is pretty there is no question about that. The UI is quite unique and intuitive and looks great for a tip calculator app with the little coffee spills and what not. If you just want to add the bill and spit it the app lets you do that. But if you want to add options like rounding, sales tax support, and tip percentages the app does have the option to do that. You can set your favorite settings and the app will remember that and while splitting the bill you are given the option to edit these settings manually. The app ticks most of the features that one would look for in such an app but it was unfortunate to find that there was no option to split the bill unevenly and the option to email / sms the report to the parties involved.
