My First Metro App - Currency Converter for Windows 8

Currency Converter logoFinally, here comes the Windows 8 port for my Windows Phone 8 (and 7) currency converter published 3 weeks earlier.

There was no real need for it, excerpt for the Microsoft’s challenge to create an application and get 100 installations by the end of September (so I still have a week!). Anyway, the result is good and even useful, which is quite unusual for Metro apps.

I have to operate 3 currencies on a daily basis, and therefore I have to use converter. But I wanted to get rid of advertisements and privacy issues. For example,  the XE Currency converter, apart from usual advertisement, has a problem with privacy. For some reason it sends to its server a lot of irrelevant information, such as the model of my notebook. Why? I have no idea, but I didn’t like that.

So, when I had to create the first Metro app, the topic of choice was very obvious and not very original - the currency converter.

The saga of certification and myth busting (remember the “just copy your code to another platform and it works!” fairy tale?) will follow soon, but for now - Ladies and Gentlemen, you are very welcome to install and use the brand new free currency converter for Windows 8.

My First Application for Windows Phone 8

by Dmitry Kirsanov 1. September 2013 16:33

It finally happened - I am releasing my first application for Windows Phone 8. And Windows Phone 7.1, for a change. Taking into account the average (in all meanings of that word) quality of applications in Windows Phone Store, I should be proud of myself.

If, by chance, you own a Windows Phone device, and in need of a currency converter for Windows Phone, I highly recommend this app, as it’s the most advanced one in the store at the moment, and will become even more useful in time.

Here are the few images of it that you can also see at the store:

I really like how it looks and works so far. Planning to release its Windows 8 analogue in a few days.

If you are planning to give it a try, let me know what you think and what else you’d like to see in it. Your feedback is important!

How To Ruin a Good Idea, part 2

New technologies allow us to reach new goals. Different tool sets enrich scenarios and it becomes easy to do things we couldn’t dream about before. We implement features so fast, that sometimes we just can’t analyze the impact until the most loyal customers uninstall our app.

Once upon a time I’ve downloaded the mobile application which made my phone a toy that could be handed to a kid. Just like the Kid’s Corner in Windows Phone 8, but for Android. It contained a few badly written games, but it was not the reason why I uninstalled it.

In Android, just like in Windows 8, you can use other apps to enrich your application with their services. Connect to social networks, send e-mails and whatever else.

What this particular application did – it used my e-mail application to send e-mail to developer of that application, to automatically register me as it’s user. I realized that only when I’ve received an e-mail with the password and warm “thank you” for registration which I didn’t commit or solicit.

In some countries that’s crime which could cost you your business.

The morale is – sometimes you can’t do what you can do. You can use contracts in Windows 8 (or their analogs in Android and iOS), but you shouldn’t do anything that your customer is not aware of and can’t cancel before it happens.

How To Ruin a Good Idea

Here is a short story of a good idea gone bad, and a good lesson for mobile application developers.

The Preamble

We find ideas everywhere. The best place to find a good idea is where you wouldn’t look for it. The dump, graveyard, museum, park or simply the street of your city at night (in other words – any uncommon place for you) may bring something that would keep you busy for the next year. Or show the pitfall to avoid, and sometimes this knowledge comes with the price.

The Space In Between

A5 chipYou’ve already heard about the Windows Phone operating system. Microsoft invested a lot of money into making you hear about it. They are trying to form opinion and clear up the niche for their new attempt to settle in the mobile phone market, and this time it appears like they went for broke.

It’s not only huge resources spent on all sorts of advertisements, but also the unusual amount of FUD in their pitch. One of such arguments that riveted my attention is that iPhone is a glamorous gadget for non-geeks. If you believe it, then this article is for you. More...
