I wanted to like this app, but there were a couple of deal-breakers. One: there's no one-and-done option for paying to remove ads, there is only the monthly subscription option. Frankly, for a simple calculator app that's ludicrous. Another is that the tip calculator only gives you the option of entering the post-tax bill amount, not a pre-tax subtotal. Only the latter is useful for splitting bills. So while I like the versatility of the other things, it's just not worth it.

Thanks for the detailed feedback — totally fair points. For ads: we currently offer subscription only, but it’s roughly the price of one cup of coffee per month and unlocks multiple features, not just ad removal. For the tip calculator: enable “Do not tip on tax” to calculate tips from the pre-tax subtotal, which is better for splitting bills. 🙏

Works great and has all the different types of calculators I ever need in one app. I mainly use this for calculating discounts but also use for determining sales tax and tip amounts, for converting units of measurement when cooking/baking, and that's not even all that it can do. You can convert currencies, determine BMI, calculate ovulation, dates, GPA, fuel efficiency, and cost. Literally everything, and it's free, so there's no reason not to.

As an American expat living in the metric world several time zones away from the USA, I find this app to be outstanding. It is not the first conversion calculator app I have tried, but it will be the last. Besides calculators useful for expats it also has health and consumer-related ones. It is extremely easy to rearrange the menu so the calculators you use most often are on top. The ads in the free version are small and unobtrusive. This is a well designed, easy to use, and invaluable app.
