BEST RATED TIP APP EVER

Check out these reviews (Thanks for those, BTW!):

 

Has everything you need in one nice, quick screen with great UI. Thanks.

 

It's the best tipping app out there. Well worth the money.

An elegant app that really works. This is the kind of thing that makes you proud to whip out your phone after dinner!

Tried many others... this is the only one that remains on my phone.

The best tip calculator ever. Genius.

INTUITIVE, GORGEOUS UI

Upon launch, use the large keypad to tap in the price of your meal.
Swipe the slider to set the percentage. The App remembers your preference.

Split the bill evenly among friends using the second slider. The tips get split too.
Adapts to your currency and to these languages: English, Spanish (more coming soon).
Use the "Mirror" mode to confirm that every food charge in your credit card bill has mirrored digits (like $37.73). The numbers in the amount will not reflect each other if someone tried to skim a bit off the top.

FROM SEATTLE, WITH LOVE!

Thank you all for your awesome feedback and reviews. I have tried to build an App that fits in perfectly with the iPhone. I hope it finds a good home in your phone and I look forward to your ideas and suggestions.
