5/5Time management
Great to use with customers in real time to set pricing. Easy to use interface, takes the guess work out of margins and profits. Having this tool has helped capture sales on the spot.

2/5Bug - App freezes when changing % in settings
I just downloaded the app today and it works fine until I go into setting and try to adjust the % min and % max. The window freezes on the calculator and my only option is to uninstall and reinstall which resets the settings to default - same freeze happens when I try again.

5/5Incredibly convenient
This is an awesome tool, one of those great ones that makes you say,"Wow, so glad I own an iPhone." Beautiful presentation, the ability to find profit percentage forward or backwards, and flawless execution. 5 stars.

5/5Awesome app! Best $1 spent on an app yet!
This is a brilliant tool for business. Quickly calculating margins, profits and impacts of discounts has never been easier. Sure you can do all of this with the built in calculator, but why would you? You'll look like a bumbling fool as you franticly punch in numbers trying to negiotiate a sale price. The ability to quickly see what impact a price, a percent discount or a dollar value discount will have on your bottom line is fantastic! Update: Version 2 just made a great app even better. The currency conversions are very handy and the snap slider makes it easy to hone in on that perfect price. Update: Version 4 adds yet another round of great improvements and features. The 4 function calculator on rhe number pad makes it easy to tally up a list to calculate cost/price. This developer keeps adding and improving! Update: New name. Still the best margin calculator in the App Store!

1/5Worst calculator
Very hard to use and confusing, does not calculate correctly sometimes. Waste of money and time. Please do not pay for this app or use this app. Save your money and time for better app than this one.
