Between Sheet app for iPhone and iPad

This application is a Date and Time calculator.
Repeating a similar calculation is sometimes necessary. Full number input again and again is a nuisance. Dont you think its better if the calculation result comes only by different point correction? This application fulfills it.

After getting the calculation result, you often have the demands such as follows.
・The other results when the input varies.
・Adjusting the result to the desirable value, inverse calculation of originally input part.
This application allows a touch action to displayed number itself and does numerical value correction or input.
It makes simpler and easier the operation (correction, recomputation) like above cases.
