I have been using this app now for about a week and finding that it’s a joy and useful utility. I love how it asks you if it can use your location in order for it to find the sales tax for your list. This is very helpful when you don’t know it or want to confirm what you believe it to be. I actually knew it and the app was able to reinforce the sales tax amount in my region. It even gave me the location in which I was in when figuring the sales tax automatically.
