Description by Jos Staneke Written by the developer, not by AppBrain. Click to read.

A simple calculator for some common problems.
The main feature of the app has to do with percentages.
1. You have an original value and want to calculate the end result when a positive or negative percentage is applied to it. Example: 50 + 10% = 50 + 5 = 55
2. You have an original value and a result value, calculate the percentage (increase or decrease). Example: 80 +?% = 84 -> 5% increase.
3. You have a result value and a percentage and want to know the original value. Example: 127.50 end result and a 15% discount = 150.00 is the original value.

Furthermore there are some common calculations for circles and triangles which carpenters use a lot.

A BMI calculator is built in too if you wan to check your health.
And to help with conversions, a length and weight converter is also built in the app.

This app does not require a network connection for any calculations.
The only time a network connection is required is if you want to check the privacy policy.
