Luna Calculator Review

In most cases you’ll be perfectly fine with the built-in Calculator app, even though your iPhone has a lot more to offer. Just like with other built-in apps, which are very useful and essential in many cases, the App Store offers some very interesting alternatives. We already talked about several Calculator apps, which are designed to offer completely different user experience than Apple’s own solution. In this article we’ll continue to show you this kind of iOS apps, and we’ll focus on an app named Luna Calculator.

According to its official App Store description, Luna is a simple and smart calculator. In practice I’ve learnt to expect some very intriguing features which is the only way to beat Apple’s Calculator, so I was very interested in seeing what Luna has to offer. You can download it for $1, and there are no in-app purchases.

Luna Calculator 1

After you start this application for the first time you’ll be greeted with a tutorial video. My recommendation is to focus and try to remember what this video shows you, since this can resolve some initial problems and dilemmas. There’s no way to replay this video, which seems very odd, so all you can do is to try to remember it the first time. Once you get to the main screen, you’ll see a nicely designed UI and a very typical calculator layout. Typography is very clean and elegant, while even though you’ll be able to see a dark theme at first, you can switch to a lighter version if you shake your iPhone.

Speaking of layout, you’ll get to use your standard operators, numbers, percentages, positive/negative, a delete key, brackets, and equal sign. Once you start typing you’ll get to see the whole expression on the screen as well as the end result. What’s interesting about Luna is that you can save each one of the expressions that you use by giving it a name and saving it. For example, if you’re going on a trip you can calculate all kinds of different expenses and save them individually. This way you can always go back and readjust the calculation, but you can also use their end results in order to get the total amount. It’s actually just like using a spreadsheet, even though Luna is somewhat more difficult to use.

Even though I can see the potential behind this nicely designed calculator, it’s simply not as intuitive as it should be. It will certainly take some time until you learn your way around, and not everyone is ready to invest their time in an application that should be simple to start with. Another problematic point is Luna’s performance. I’ve tested its 1.0 version which turned out to be somewhat buggy, which means that I experienced several crashes.

Even though Luna is exceptionally designed and brings interesting animations, it lacks several important aspects of functionality. Even though you can invest your time into making the most out of this app, it’s easier to look for another calculator in the App Store that will instantly do the job.


Numerical Review

In case you’re a developer trying to create an iOS app that Apple already supplied as a stock app with every iOS version, than you’ve got a very difficult job to do. On the other hand, your efforts can be worthwhile if people respond well to your application, since there are a lot of iOS users who are willing to replace some of Apple’s stock apps. That’s why we can see thousands of incredibly powerful weather apps, to-do managers, and calculators as well.

In this article we’ll talk about a calculator. Sure, there’s nothing wrong with iOS’ default Calculator app, in case you’re using it for basic calculations. There are some incredibly powerful complex calculators in the App Store, which are the main tools of work in many professions. Still, we’ll tell you more about a simple calculator app that brings amazing design, which is its main selling point. This app is called Numerical (Calculator Without Equal), and you can download it for $3.

Numerical 2

As I said in the previous paragraph, Numerical is trying to replace Apple’s own Calculator app. This means that you’ll be able to use it for basic (or non-complex) operations. It brings great UI design, clearly inspired by iOS7, but it also brings several small features which are there to give identity to this little app.

The first time you open Numerical you’ll get the see a short tutorial which will give you some basic information. Once you get to the main screen you’ll get to see nicely designed UI that could be one of the best examples of flat design. It features striking gradient of purples and reds in the background, while the typography is very light, but noticeable. I am sure that there are some users who don’t like this kind of minimalistic typography, but this app is designed for those who are in love in iOS7 and its freshly introduced flat designed principles.

If you take a closer look at the screenshots, you can notice that Numerical comes without “=” button, which means that you’ll get the results instantly. This button is omitted in order to reduce one step in the calculation, and to free up some space on the screen. It might take some time until you get used to this, but this is nothing serious so I am sure that you’ll quickly learn your way around.

Speaking of some features that Numerical brings which are unavailable with Apple’s Calculator app, there are a couple of them. For example, you’ll get to review your entries by swiping to the left side of the screen where you’ll see your history of inputs. You can copy any entry from this list. Also, if you need to use previously used answer in your next equation, you can swipe down across the answer in order to insert it. These little additions are very interesting, and they can be very useful as well.

Numerical is very interesting iOS calculator that can successfully compete even against iOS’ stock app. Even though some people won’t like paying $3 for an app that they already have on their phones, I would still recommend trying out this interesting app.

Calca Review

In today’s world of simple and complex text editors it seems that we already have all we need with the current selection of OSX and iOS applications. Newly released text editors are now trying to bring enhanced UI design which is very minimalistic most of the time, and they also try to bring one major feature which should at least seem unique or interesting enough to become a major selling point. That’s why I was very surprised once I started to work with Calca.

Calca is a text editor (available both for OSX and iOS) which is able of handling your text input just like any other similar app, but it comes with a very important feature that actually shapes its usability. It’s able of understanding written language and perform some calculations based on your input. In some ways, this application could be seen as a very interesting combination of text processor and a spreadsheet app. And it works quite nicely.

Calca 3

Calca is a text editor which is designed to understand your inputs, so it can perform calculations and provide you with an end result. This way you can create structure of some calculations that you use on a daily basis, so by changing inputs you can actually do the same calculation over and over. For example, you can calculate your spending towards your monthly budget by writing categories like “car = 250$”, “food = 500$”, and for example “rent = 1200$”. Now you can type in a command like “expenses = car + food + rent”, and this should calculate 250+500+1200 and give you the result. In order to see your daily spending you can type a new command like “expenses/30 days” so you’ll get the result of 65$ which is how much you spend on a daily basis. As you can see you need to think logically and if you’re really good at math and calculations, you’ll be brilliant with Calca. Also the good news is that Calca brings a lot of predefined calculations and template documents, and there are numerous practical examples on its official website, so there’s no shortage of support material.

Calca 2

What’s important to say is that this text editor is able of calculating even some very complex operations. For example, you’ll be able to work with variables, functions, equations, matrices, and many more.

When it comes to UI design of this app, it’s very simplistic and looks like just about any plain text editor. This goes for both OSX and iOS versions. You’ll get to the status bar on top, and the rest of the window will be a blank canvas where you can type and calculate. You’ll be also able to use Markdown syntax in order to format the text, but there’s no preview mode which is a real shame. I hope this will be added in a future update, since this would mean a lot to those who use Markdown on a daily basis, where the preview mode is simply essential.

Calca can be purchased in the OSX App Store for $5, and also in the iOS App Store for $3.

Vert 2 Review

At some point in time we all needed a bit more advanced calculator or even a reliable converter that we usually searched for and downloaded from the iOS App Store. As you’ve realized, the available choice of these simple tools is amazingly large and these apps usually offer their “free” editions, which are in most cases plagued with ads and all kinds of annoying stuff. That’s why I always prefer paid solutions, especially when it comes to highly usable apps like calculators and unit converters. Plus, these applications are usually priced from $1 to $2, so everyone can afford them.

In case you still haven’t found a perfect unit converter, than continue reading this article. I’ll show you an iOS application that brings amazing design and excellent functionality. This app is called Vert 2, and it’s priced at $2.

Vert 2 1

Vert is a typical unit conversion tool, which means that you probably already know what to expect in terms of functionality. This little tool will surely surprise you, and the first surprise will happen when you take a look at its gorgeous interface. Vert has been updated to its second major version just a few weeks ago, and it brought incredible iOS7 inspired design. Colors are minimalistic and they are used to signalize chosen items, while typography is very clean and minimalistic as well. There are no toolbars or status bars, so all you see on the screen are units and input numbers. This doesn’t mean that Vert is overly simple, since it uses nicely integrated gestures to flick through different screens and to choose from dozens of categories. You’ll be also able to customize its colors, so this app can really complement your iPhone 5C, in case you use this iPhone model.

When it comes to functionality, I can only assume that Vert is going to cover your every need. It comes packed with 33 categories, which contain up to 900 units. As you can imagine, these are mostly units of measurement, but you can also use currency and clothes size conversion tools. There are even some funny and very unusual units, which are there for your amusement. I am not going to explain these units, since I’d like something to leave for you to explore.

Finally, there’s one feature that I’d like to mention, which seems unique for this type of iOS application. Vert allows you to search from two units which you need to use, simply by using its search bar and writing names of those two units that you’d like to use. This makes it much easier and more convenient, instead of browsing every time for a right unit category.

There are big chances that you already use a unit converter which meets your needs. This way I can only recommend Vert to those who like a very nice UI design, and to those who are still new in a world of iOS apps. This will be the best $2 that you’ve spent in a while.

PCalc (3.0) Review

While some developers are trying to come up with some kind of new, exciting, and innovative applications and to offer them through the iOS App Store, others are trying to rework Apple’s own built-in apps and upgrade their original features. Both of these groups of developers are in a difficult position, since both ways demand a lot of time and effort in order to make a product that will stand out. It seems that the bar is being pushed even higher with each new week, since the iOS App Store is getting crowded with great applications which only cost a few dollars.

In this article we are going to take a look at an application called PCalc. In case you’ve just upgraded to iOS7, than you’ve probably noticed its nicely designed blue icon in the featured section of the iOS App Store. By knowing that Apple decided to showcase this calculator, even though every iPhone comes with its own calculator app, tells you that this app has a lot of potential. Now let’s see why you should use PCalc instead of Apple’s own Calculator app, and what features can you get.

PCalc 2

If you’ve upgraded to iOS7, than PCalc will perfectly fit into the overall aesthetics. Starting from its icon, which respects the newly introduced flat design of iOS7, you can see that the developer took their time and made sure to pay attention to details. Once you open it you’ll get to see a standard calculator interface, which is also very flat and nicely designed as well.

As it turns out, PCalc has been around for a while, so this is not a new app. The version we’re reviewing in this article is 3.0, so I guess that many users will be happy to have an application in constant development. This also means that even though the newest version comes with a completely new interface and new functions, you don’t have to say goodbye to old ways because they are now simply hidden beneath the surface. Once you go to PCalc’s preferences, you’ll get to see different themes and a lot of fine-tuning as well.

What’s important to say is that PCalc is not only a nicely designed application. It is actually more powerful than Apple’s own solution, and that’s the main reason why users love it. For example, you’ll get to use hexadecimal, octal, and binary calculations, as well as different kinds of notations and numerous functions. There’s also a unit conversion that you can use.

Even though this is one of the most powerful calculator apps that you can use on your iOS, many will have a problem with its price of $10. But PCalc isn’t made for those average users who only need a calculator from time to time. This one is made for serious power users like programmers, engineers, and students, who will benefit from all of those numerous features. On the other hand, you don’t need to spend whole $10, since you can also use its free version, and unlock parts that you need the most.
