Cali: interesting calculator for iOS with control gestures (+ distribution of promotional codes)

If an analysis of the number of similar applications, the most common in the App Store - sure leader of the list will be calculators. It just so happened, and it's kind of a tradition: after writing the promised «Hello world», developers are taken for the establishment of a calculator. It is for this reason that the App Store there are thousands (issued in 2200 Search results for query "calculator") and all of them, frankly, "one person". Recently, I accidentally came across a curious calculator Cali and tempted by an interesting statement functionality (control gestures) decided to try it. Looking ahead, I will say that I do not regret!

As I learned later, is a developer of Cali Austin Valleskey - 15-year-old high school student from Chicago, Illinois. Deciding to try his hand in the App Store, he was puzzled creation of a calculator, and to distinguish themselves from other competitors, he used his calculator gesture control.

The decision is quite logical and correct, as if to recall the iPhone use the script as a calculator - usually we need just a quick something to count. Add, multiply, divide and subtract. Once these basic operations, and for all cosines and cube root mainly use more severe instruments. Here and useful gestures that supports the hero of this review. After entering the number is enough to swipe in the appropriate direction and the necessary action will be activated. But let us all in order.

first look

The design of the application is made in the spirit of iOS 7. Minimalistic, simple and intuitive: the digital unit is designed in bright colors, and panel operations vice versa black with white numerals distinct. In the next version of the developer promises a few themes that everyone can choose their liking. Most of the screen space allocated digital block, large font used for numbers. While for the tiny font is selected action buttons, because instead of clicking on them we are invited to use gestures. Buttons also work when you press, but their main purpose is the display of the current action (they are highlighted in blue).

Manage gestures

We now turn to the application a snap - gesture control. It sold for the four basic operations: addition, subtraction, multiplication and division. Each action corresponds to a gesture, such as a single finger swipe down - to subtract, or swipe to the right - to multiply. The rest of the math (roots, squares, sines and tangents) are also available in Cali, but work by simply tapping and hidden button more. I think this is the right decision, because we almost never use it, and it makes no sense to clutter up their screen space.

How it works?

In fact, control gestures quite comfortable, the only thing that did not like - to count the results vseravno need to press the button equally. With the number of clear them in any need to enter the pens, but the counting result it would be logical, too to do in sign - horizontal swipe with two fingers remarkably fit into the overall concept of sign management. Other than that, everything works fine: gestures are recognized correctly, there are no errors in the calculations.

reference

By the way, the developer has provided the help page, which can be found by clicking more — pro tips. Here is a description of all the gestures used in the application, in addition to the four basic mathematical operations have gesture for copy number on the clipboard (tap retention) and for the removal of the input field (on the left swipe number).

Support

The developer is actively developing their offspring, improving and adding new functionality. Soon update should come out and there we are waiting for different themes (in the color tone of the body 5c) and the correction of errors: too loud click buttons are pressed; adding to the result entered digit, instead of erasing after clicking equally and other improvements. The big plus is that the developer listens to the wishes of users and quickly respond to the comments.

disadvantages

At the current moment, Cali has several disadvantages. This lack of computational chain (let's call it so) when we click 2+2+2+… and the result is continuously updated, allowing to conduct quick calculations. Also, while Cali can handle only four-digit number, for most users this is enough, but some people may be a little. But I'm sure the developer will eliminate these annoying flaws in the near future.

I would like to see

I would advise the developer to improve some important points that will make even steeper Cali. Be sure to make a gesture for the action equally (Eg horizontal swipe with two fingers). Also, review the current basic gestures for action: e.g. logical add numbers swipe down (to itself), and vice versa svayp take up (away from you).

Total

Given the minimum application value for money, interesting functionality and responsiveness Developer - definitely can recommend the Cali to buy if you are looking for a replacement of the standard calculator. As for me, I did.

While writing this article, I talked with the developer, and he gladly provided us with more than one code, that we traditionally raffle among our readers. To take part in the draw, share the link to this article in any social network and unsubscribe in the comments.

P.S. Austin was very pleasant and sympathetic person and promised to make proposals to improve in the near me an update. If you have any ideas or suggestions about Cali functionality - expressed in the comments, they will be taken into account!

UPDATED. At the moment, it has already released version 1.2, in which the developer has added themes, icon updated and corrected some minor errors.
