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.

A bit disappointing that you decided to go to subscription based payment only to get rid of ads instead of one-time payment (which I would have gladly paid for) for a calculator. Too many app developers lately are getting a little too greedy. Is a one-time payment for your product not good enough? Getting a little tired of this.

SUBSCRIPTION-BASED W/ OBTRUSIVE ADS It used to be that there would be just a simple ad banner in the bottom, I was cool with this. But apparently they decided to add ads that waste your time trying to load their content and completely prevent you from using the calculator while doing so. All on top of still needing to watch the ad afterwards. "Why not just buy it and remove the ads?" Because you CAN'T! It's a subscription-based CALCULATOR so you can't just pay once and be done with it. Unusable.

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.

I love using it! It's so much better than my laptop calculator that I'll pull out my phone to use this app rather than my laptop's. This one lets you keep your whole calculation typed out while also giving you the updated answer based on what you inputted at that moment as opposed to some other calculators that only show you the current number on the screen. Interface is great too! Has ads, but they're small strip ads on the bottom so it's almost like having no ads at all, which is really good.
