This app includes Apple Watch app!

When shopping if you want to compare several similar products with different package sizes, this app immediately shows you the cheapest product after you input the number of items and prices of these products. For example, which one is the best buy: milk chocolate with different sizes, washing machine powder with different weights, and etc.

Initially I made this app for myself because I failed to find a similar app. Then I realised this app should be shared because I believe it is super fast and easy to use, gives you the result exactly you want immediately, and is suitable for frequently use. Now with the help of the Apple Watch app, it is even more handy.

In many cases we feel time flies, because we wasted a lot of time on unnecessarily tapping buttons or inputing characters. This app is so elegant that any unnecessary step is removed. Over a period of time you would realize you actually save significant amount of time, just like we all use some keyboard shortcuts on our desktop machines (for example: copy and paste).

Due to limited screen space on Apple Watch, please note: the top middle red "R" button is the "reset" button to reset all the input text fields.
