Bowtie ∞ Tip Calculator

By Carlos Perez

Open iTunes to buy and download apps.


Get a Tip Calculator so sleek and efficient it feels like it always belonged in your iPhone. The elegant interface is full of intuitive touches to help you do exact math while staying out of your way.

To use, just launch and tap in the price of your meal. Use the sliders to set the percentage and optionally, split the bill evenly among friends. Calculations can be made to the penny, or rounded to the nearest dollar to your intended tip percentage. You can even encode a pattern in your total amount to prevent theft! With the Mirror mode, you can confirm that every food charge in your credit card bill has the dollar and penny digits mirrored (e.g. $37.73 — a palindrome) and that nobody tried to skim a little off the top.


Review by Micah D:
"Launches fast, does the math an gets the job done. Doesn't bug you with Facebook connection or anything like that. The best tip calculator in the app store"

Another v2.0 review from a long-time user:
"I've tried many tipping apps and this has always been my favorite."

♥ From Seattle, with love. ♥
Thank you all for your awesome feedback and reviews. I've tried to build a top-shelf iPhone App with the fit and finish you’ve come to expect of the iPhone. There are bland imitations out there, and confusing apps with jumbles of badly arranged features. I'm confident you'll find this app is a worthwhile upgrade to your iPhone, and I look forward to hearing your feedback and ideas.

What's New in Version 2.0.1

v2.0.1 should work for Verizon folks, sorry about that.
New name —tell your friends— and finally: Retina Display graphics on your Tip Calculator! If you appreciate that, please try out feature number two: The bowtie is now clickable!

It's Simple, It's Fast, It's Great

5 stars means "it's great" according to Apple, and that's just what this app is. My favorite thing is that as soon as you open it, it's ready to just tap in the bill amount and presto - you've got a tip ready to go, and it remembers and re-uses your last options for all the settings. What could be simpler? My ONLY wish - and it's minor - is that since I eat alone a lot, I wish I could round to the nearest $0.50 instead of the nearest whole dollar. But as soon as i eat with just one other person, it's no longer an issue due to the size of the check

Great App..! User Friendly..!

I have been using this app for quite some time, easy to use. I figure what % I want to give then round the tip up or down from there. Rounding of the tip would be a nice addition, but it's still a great, easy app to use...
Thanks for finally explaining what 'mirror' means, I always wondered about that!! The developer explains on the app page description in the app store...

The mirror function is a great idea

which is why I didn't rate it one star. The problem with the app is that it doesn't take into account tax. A restaurant tip is based on the pre-tax total. Which is fine if you just want to get a straight up percentage tip with this app-- just enter the pre-tax amount for the meal total. But the mirror function doesn't work the same way; either you have to tip based on the post-tax total or it doesn't work.
