There is no need to go through multiple views to select the units. Just rotate the wheels. And the calculation is done as you type. Four most frequently used conversions can be assigned to favorite buttons. Just hold one of them after the category and units are selected. Short vibration and changed symbol on the key lets you know that the programming is done.
And what if you would like to quickly swap the units? Just shake the iPhone and voila, instead of e.g. EUR to USD you get it reversed. Don't want to attract people around with shaking movements? Double-tapping the program's display leads to the same effect.
Another unique feature of Measures is the built-in calculator which is hidden by default. One use case of it is entering of negative numbers (mostly for temperature conversions). But not only that. The calculator allows to perform all basic mathematical calculations as well as advanced ones (powers, logarithms etc.). In addition, the rounding slider on the extended calculator allows you to change the precision with which the conversions are done. The calculator is activated with the single-tap of the program's display.
Every aspect of the program is well though-out. Even entering of numbers for conversion. There is a back-space equivalent which is a short tap of the CLEAR button. Hold it and after approx. one second, the complete input is cleared. Alternatively, you can just swipe with the finger over the calculator display to literally wipe the entered number.
Measures has evolved over the time. Many new units were added which became harder to manage. And the solution is now implemented in 1.2.0. All categories and corresponding units can be freely rearranged and deactivated if they are not needed. Sorting of categories / units can be done based on alphabet, frequency of use or unit weight factor (e.g. in is less than ft). All this can be done in the comprehensive settings menu.
