Calculator 3.0

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 😁.

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! 😊

I was trying many calculators for Apple Watch and by far this one is the best. One thing I don’t like when using this calculator in Apple Watch is that I have no idea which “operational” button I previously pressed. If you can highlight the recently pressed button with a different color, it will be better. Then I will know if I had pressed a wrong button.

I’ve spent quite a bit of time trying to find a good calculator for my Apple Watch. This app is so close to being perfect, except for 2 things I wished it had... The first would be that you could still see the input area as you scroll down the calculator options (i.e., if you scroll down, you can’t see what’s being typed any longer, so if the input area were frozen along the top of the screen, it would be much better). And second, I wish it showed the operation in the input line (i.e., showed the written out equation so you felt more certain that you had typed correctly on the tiny buttons). If the developer updated these 2 things, this would easily be a 5 star app.

I was using another calculator app that worked great for quite some time, then out of the blue it started being unreliable with its figures being inaccurate for some reason? So that lead me to looking for another calculator app and I’m now using this one for my basic arithmetic needs! It does as it should and I’m hoping it will continue to work flawlessly? If anything arises I’ll update my review at that point. For now it deserves its 5 stars easily! UPDATE: unfortunately after using this calculator app for a while I’ve learned it’s very unreliable! You can add Or multiply, etc. the same numbers 4 or 5 times and get a different answer for the total every time! Certainly can’t count on this app for adding your household bills!
