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.
