Calculator 3.0 4+

Exactly what I want in a calc!

I’ve tried a bunch of calculators on my iPad. They were all cumbersome to use, had a poor GUI, or focused too much on features I don’t use while making those I do use a pain (thus cumbersome to use). Some of them didn’t even have an easy way to store a number in memory! I mostly use a calculator for quick dilution and cell counting calculations in the lab. So, Hingis like a handy exponential function are key (if I want graphing, regression analysis, or model making, I’ll use my friggin computer). For what I want in an iPad calculator, this one is perfect! It has a simple, elegant looking interface (closest one to the iPhone calculator I’ve seen), and is quick and easy to use, but also has plenty of powerful/diverse functionality for my purposes. I agree with others that it’d be worth paying for, but there’s something I find very appealing about an honor system-based option to leave “tips” (something from my strident open source free-/share-ware days, I guess). So, if you get this app, and you like it, then hit the ℹ️, leave a tip, and support good dev’s 😁.

Thank you very much for leaving a kind review. The support helps, best of luck in all your research.

Supports iPad, iPhone & Apple Watch, Tips payment!

I have seen too many competitors that don’t offer an Apple Watch companion app and those that did wanted a monthly subscription for “technical support” issues...for a calculator app? Why do I need multiple themes and technical support for simple calculations on my devices?

It is a shame that we have gotten to iOS 11 and there is still no native Calculator from Apple on even the iPad Pro! I doubt a native app for the Apple Watch will ever see the light. I use this device for work and must quickly add simple and moderately complex math on the fly. Until that day comes, this app will definitely do the trick!

I am a huge fan that the Split View and new Dock, Drag & Drop features with with this app! A simple swipe up to change between light mode and dark mode was clever! My favorite feature, no ads or monthly subscription required! For this I tipped the maximum because I really, really believe this app was done right!

I agree with another reviewer that I would have paid for this app, but maybe the tip feature is a better go. I imagine if the developer keeps adding new and useful features that I really enjoy, I would keep tipping! 😊

Hello,
Thank you for the Review and Tip. Great to hear you enjoy the app! Reviews ensure I keep the app updated with the goal of providing all users no matter their device a simple easy to use scientific calculator. (No ads, 100 themes, weird fonts, or hidden purchases). Until Apple provides a calculator for iPad, Apple Watch and Apple TV — Calculator 3.0 will be here.

Near Perfect

I’ve tried several different calculator apps, but was primarily looking for one that would work well on my Apple Watch and offer haptic feedback. This one is FINALLY exactly what I was looking for!

Just a perfect blend of simplicity and customization options, along with an easy to use tip calculator. And all for free! I will be putting a little something in the developer’s “tip jar,” because hey, this app is so worth it!

Only possible improvement would be if I could make the “click” when pushing buttons a bit louder. Other than that, this one is perfection!
