Tokyo Blue, if you are a new iPhone user you should be aware that you will randomly get a bad install for any app in the app store. I had thousands of downloads yesterday and this is the only complaint I had about crashing. You need to restart your iPhone, delete the install and reinstall the app. Finally, please use the support link for questions and issues and give us a chance to help. It is much more pragmatic. Thanks to everyone for your feedback.

I purchased as a free app and the update is free. Just click Buy App and iTunes will verify your previous purchase and update for free. This update didn't show up in iTunes when "Checking for updates" nor on my iPhone App Store Update check. This is a great app that is quick and easy to use. Sure you could do the math but this app is well thought out and very quick and easy to use. It's the best of it's class. Excellent customer support.

I looked at lots of the tip calculators but this is my favorite. TipTap has an easy to use control of the tip amount and remembers a default setting. The new keypad entry is the best looking and easiest to use I've seen. Stable, fast, and accurate.

simple, elegant, well executed!

I downloaded it, opened it, clicked turn on tax and it crashed my phone. Not a good first impression, so I deleted the app.

Simple and easy to use without a lot of useless features.

Does exaclty what it should do and does it well! I love the round up feature! Definitely worth the free download!

this thing helps a lot because i dont know how much to give the waiter .... i think you should get it

Type in your amount, scroll to how good the waitor was and bam, you are done. It a simple app that is a quick download and works how it should.

I love this app, it's great. Much better than the previous free app I had for this.

Great app. Worth downloading. It even gives you the option of rounding up.

Clean interface, easy to use, and free. Nough said.

Awsome program! Simple, elegant, and easy to use.

Very nice! Wishlist: Round up of tip amount, Option to tip pre-tax amount, Divide total for groups.

Too easy & FREE! Thank you!!!

Basic, simple, clean interface, and it's free. Works perfectly.

Best tip calculator I've used so far.

Good but the keypad should be more iPhone optimized. 5 stars if it was the same as the phone keypad

This is a great app. I have tried many other free tip app and deleted them all. I find myself using this app way more that I ever thouht I would. This is a simple app that does its job simply and quickly. Get it, try it and you will keep it.

Finally a tip calculator that gets the basic job done well. The "round up" feature is a nice touch and shows the app was writteen by someone who understands the target use well - thanks! Ability to split would be a nice extention.

Looking for fancy options? You're not going to find it here. This is a simple app that gets the job done. GUI and functionality work as expected - the big % selection wheel is great. The best thing about this app is that the tip and total are dynamically calculated. Just enter your subtotal and select the tip % and watch the numbers automatically calculate. Saves the user an extra step - fast and easy.

I got charged .99 cents though it's free

I wish it had the ability to split checks like iTip. Love the rounding capability. If I do round, it would be nice if it told me what the actual tip percent is like iTip does. So I would say the interface of this is nicer, but iTip has some better features.

This app is a life saver. I live in NYC and regularly dine out with friends. When it's time to pay the check, it's always a headache.... But not now! I love that it is completely adaptable to the scenario you're in. Two little bugs/ areas to fix: 1) when both subtotal and tax are displayed we should b able to enter in either field when the keyboard pulls up. Other apps allow this (eg. iPoints), 2) when I change settings, I have to quit out of the app and re-open it to apply the changes. These are small annoyances which seem easily fixable. Once addressed, this app gets 5 stars! Definitely worth downloading!

This is the 4th tip calculator I've tried. It's the easiest, cleanest, and fastest from opening it to having an amount. I happily deleted the others, except 1 called Mealsplitter that separates drinkers from non-drinkers & gives u a total. When you're broke, it helps not to pay for part of your friends' 10 beers when all you had was fries.

Something that I wish developers would keep in mind. If I only have to enter numbers in any part of your app, don't use the full keyboard. Use numeric keypads! A small touch which makes a huge difference.

this is the 3rd free tip app - and thankfully the best one is also free.
