Ez Bill - Tip Calculator 4+

This app would be perfect if it weren't for the fact that you cannot add tax to the subtotal, instead the app assumes you've already did the math on the tax, and there is no option for the math be done otherwise, which kinda makes the app pointless since you need to determine the tip on the subtotal without the tax. So lets say for example I went out to eat with friends (which would really be the point of using this app) and we all got different things; I got a drink for $12, and they got an entree for $25 and the total would be $37, i would need to know how much i need to pay on the tax and on the tip, but this app assumes you've already done the math on the tax and have included it. So there needs to he an option to have an untaxed amount which would then be taxed and tipped on. Literally the only thing preventing this app from being perfect.

Look of app is clean and simple. Works on iPad iPhone and apple watch. Also includes a cool today widget.
I did have some issues with tip showing correctly. It gets stuck on a certain tip value sometimes even though U change the rating.
Also wish it included total tip and total bill so after U collect from everyone U can count and double check all is there.
Hope to see some updates.

I think this is by far the best app for calculating tips. I usually tip on the the pre-tax amount. Few tip calculators handle that, this one does. In fact, it uses your location to determine the amount of tax since each state is different. I also like that it has an Apple watch app. My only complaint is that the number pad on the watch is not very easy to interact with and on the Series 4 watch it does not make use of the entire screen and as a result the number key is smaller and you need to really focus to make sure you are hitting the right number. I have also hit delete many times while trying to type in a 3. Even so, it is a fantastic app on the iphone and a great app on the watch.
