## i know percent Reviews in United States

### ***** "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….  :-)

### ***** "⭐️⭐️⭐️⭐️⭐️ + no ads!"
Удивительная простая программа. Было бы неплохо добавить больше функциональных возможностей в будущем.
-- Kirdetzoff, 2021-09-07

### ***** "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.
