### 1/5 — Does not work for me

*2022-09-09*

I thought this was a cost per mile calculator. If it is it does not have any type of helpful tips on how to use it. How do I get my $2 bucks back?

**Developer response:** This is not the type of calculator you were looking for! This is a “cost-per-mille” calculator for advertising, not a “cost-per-mile” calculator. You could try asking Apple Support for a refund at https://support.apple.com/en-us/HT204084.

### 1/5 — Decimal

*2010-07-27*

Are you kidding?  No decimals.

### 1/5 — No decimals?!?

*2010-06-04*

Useless. You can't enter a decimal which means it only calculates whole dollar amounts. Anyone who works in Internet advertising knows how important decimals are when calculating CPMs. I have a decimal for you: can I have my $.99 back?

### 5/5 — Hands down, The Best!!

*2016-01-06*

This is the Michael Jordan/Mohamed Ali  of CPM Calculators! The best of its kind. 
it includes a “comma” where needed which no other app like this does that. It is polished and  looks slick whether used on the iPad or iPhone. I always get compliments on it when I show it to coworkers and being in media, I use this a lot.  And now works fabulously on iOS9!

### 5/5 — Great Tool

*2011-12-28*

Simple, but I use this all the time.

### 5/5 — Useful

*2010-12-09*

Has decimals now, and better interface than the other cpm calculator app I found.

### 5/5 — Simple, Useful Tool

*2010-03-07*

I forget the CPM formulas all the time; this calculator helps--especially when I'm away from my computer.
