i know percent is a modern and elegant application for calculating percentage that works in real time. Easy minimalistic interface allows you to perform tasks quickly. We also included help screens, where you can learn about the application of percentage in real life.

Easy way to solve four types of percents:

1. Percentage increase / decrease from X to Y
2. What is the X% of Y
3. Add the X% to Y
4. Subtract X% from Y
5. X is what percent of Y?

Added a simple currency converter.

Every day, percentage is present in our lives.
Just calculate them faster with the app - i know percent.

Fine thing, but missing some points…

Add another function like “X is how many % of Y”… you have one function just opposite of this… but this is missing… add this one on next update….

Thanks for adding the asking…. :-)

Удивительная простая программа. Было бы неплохо добавить больше функциональных возможностей в будущем.

Easy to use

Upon the suggestion of iReviews on YouTube I decided to give this app a try and it’s very easy to use.

Self explanatory but has a little (i) at the top for help. No ads and free is a definite plus. Great for shopping and to calculate the % of my raise at work.

I use this to calculate the percentage of my salary from last year to this year and compare the % with the rate of inflation.
