The Calculator

7 08 2018

The built-in iOS calculator on the iPhone is well-designed but you should know some hidden features which make the experience smoother.

Swipe to delete digits

Just swipe left or right to backspace and delete the most recent entry instead of clearing the entire value.

Copy / paste

You can quickly copy and paste results or any number by using long press.

Scientific calculator

If you rotate your iPhone to landscape mode you’ll get a basic scientific calculator.

Only the scientific calculator offers the memory features mc (memory clear), m+/m- (add to/subtract from temporary storage) and mr (memory recall). This is what I sorely miss in portrait mode.

Several of Apple’s stock iOS apps that are available on iPhone don’t have their iPad counterparts. These include Weather, Stocks, Voice Memo, Compass, and the Calculator App. A calculator would also be a nice feature on the Apple Watch. I know that there are 3rd-party apps (and I nearly used them all) but if I pay a lot of bucks for an Apple device I’d like to see some useful apps included without downloading payed apps, apps showing more ad than results, or free apps which most often aren’t updated with a new version of iOS.

The worst and most featureless calculator app is the one pre-installed on devices running pure Android like my Nokia 6.1. The best calculator is still running on my Windows 10 powered low-cost Lumia 550. With it you get a clean, perfect UI and you’re also able to convert into lots of different units like Celsius to Fahrenheit. Sadly it isn’t updated any longer because Joe Belfiore made it official: Windows 10 Mobile is dead.Really? Well, statements are still cloudy.

Bugs bug you and me

26 07 2018

What I expect in the aftermath of the WWDC 2018 from Apple and the App Store developers.

Inextricably linked with apps are small animals which most aggressive life forms are well-known from tropical areas and called BUGS. Today we have them also massively in temperate zones and they are distributed for free by Apple, Google, and others.

A software bug is an error, flaw, failure or fault in an operating system or an app that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. This is a well-known problem and none of the big companies is able to avoid bugs. But it seems to me that they are also unable to massively improve their internal control system.

So if we install iOS 12 this year the same procedure like every year will start again, or can we trust in Apple’s cast-iron promise to focus on killing bugs.

I think it’s likely that we are faced with bugs we already had years ago. These little animals are an integrated part of an operating system and history tells us that we shouldn’t trust in promises of software companies wether it is Apple, Microsoft, Oracle, SAP, Symantec, VMWare, or any other of the biggest software dinos.

Apple …
Stop giving us new emojis.
Improve the software quality instead.

Optical Image Stabilization

An optical image stabilizer (OIS) is a mechanism used in a camera camera that stabilizes the recorded image/video by varying the optical path to the sensor. This technology is implemented in the lens itself, as distinct from in-body image stabilization, which operates by moving the sensor as the final element in the optical path.

Seeing is believing, and this video really emphasizes the differences between taking a video with the iPhone 6s, a device that lacks OIS, and the iPhone 6s Plus, which features OIS built in.

And here’s a other video I took with my iPhone 6s Plus while walking on a broken ground.
