[WP8] Kraken unofficial app for Windows Phone 8

Kraken unofficial app



Hi everyone, my name is Leon Cullens and I'm a software engineer from the Netherlands. I made a Windows Phone 8 app for the Kraken exchange: http://www.windowsphone.com/s?appid=a3857353-599a-434f-8293-398745723de6. Note that this is not the official Kraken app, there are no current plans to release an official app for Windows Phone.

Right now it supports these features:

• List of all tradable currency pairs and their current value.
• Details for each tradable pair, inclusing current price, high/low price and the bid/ask price.
• Live tile for your favorite pair.
• Overview of your account balance.
• Overview of your open orders (and the ability to close them).
• Overview of your closed orders.
• The ability to open new trades from within the app.

Here are som screenshots of the latest new features:





The app can be downloaded here: http://www.windowsphone.com/s?appid=a3857353-599a-434f-8293-398745723de6 or with the QR code below:

Hi all,

I just submitted a new major release for my Kraken app. It will include an overview of your balance, an overview of your open & closed orders, and the ability to close orders.

Here's a quick teaser:



I hope it will be live in the store within 5 days, but I'm not sure if it will pass certification since I didn't provide my API key.

The app successfully passed certification It should be live on your phone within 24 hours.

I've been busy with implementing trading. You can now purchase credits through in-app purchases, and the user interface for trading is almost done (see screenshot, it's more advanced than you can see at this one screenshot though). I also implemented a lot of small improvements.

[Avalaxy]

I made a few screenshots with some more details on it for someone, might as well share it here:

[Avalaxy]

I just released a minor update that should fix a couple of things, including the generic error when going to 'balance' or 'orders' when you didn't enter an API key, and entering an API key now no longer requires you to restart the app.

The trading feature is done as well, I'm going to do some final testing, and then I'll submit it. If everything goes well, and Microsoft accepts it, it should be live within a week.

[Avalaxy]

Alright, it's submitted. Here's the teaser:



Let's see if Microsoft will give bitcoin some love.

Thanks! Not sure when the iOS app will come. Payward will release an official app for that, it won't be by me. But there's no word on a release date.

Over the last few days, the story about the latest update spread like a wildfire on twitter and the internet in general A lot of websites wrote a story about it, here are a couple of important sites:

Tweakers.net (largest Dutch/Belgian tech website, around 600.000 registered users): http://tweakers.net/nieuws/93916/microsoft-laat-eerste-bitcoin-app-toe-op-windows-phone-platform.html
WMPowerUser (second largest Windows Phone community website): http://wmpoweruser.com/kraken-is-the-first-bitcoin-trading-app-for-windows-phone/
Frontpage of /r/bitcoin: http://www.reddit.com/r/Bitcoin/comments/1w4v3x/microsoft_allows_bitcoin_trading_app_on_windows/

A lot of niche sites wrote about it as well. To name a few: CoinCourant, CoinReporter, TechieNews, BitcoinExaminer, etc.

I've seen a massive increase in downloads over the last few days. Keep in mind that Kraken is growing with ~2000 users per day (December 2013), and doubling their use base every month (source). The Windows Phone 8 platform is also seeing a consistent growth every month, it outsells iPhone in 24 countries (source). In a lot of European countries, Windows Phone is the second largest OS. This coincides with Kraken's userbase which consists of 75% EU customers, 10% US customers and 15% customers from other countries (see angel.co source). Right now, Kraken is the #2 bitcoin exchange when it comes to XBT/EUR volume (source).

Another update just got published that added the following things:

- Graph on the details page
- Detailed graph when you click on it
- Slightly different design
- Button in the trading view that allows you to insert the maximum available volume in the 'volume' field
- New textboxes for the API settings (they have a button that allows you to clear the field)
- Wide live tile
- Added a loading bar
- Small bug fixes

Here are some screenshots of the new features:

[Avalaxy]

I just submitted a new major version: 1.4.0.0.

It has the following changes:

- An order book
- Fixed the labels underneath the charts to avoid large numbers of labels overlapping each other
- Added the type (buy/sell, limit/market) to closed orders
- Added an order details view that can be opened by pressing and holding a closed order and clicking 'details'
- Now sets the selected pair from the settings as the default pair for trading
- Minor bug fixes (e.g., removed the 'API key' error when refreshing while the user didn't enter an API key)
- Various small changes (e.g. added tooltips to notify the user of 'hidden' features)

Here are some screenshots of the new goods:



Another thing I've added: after starting the app 3 times you will be asked to take part in a small survey. Your answers to this survey will be of great help to me to make this app better because I'm trying to figure out what I can do to give you the best possible experience. The survey can be found here: https://docs.google.com/forms/d/1mIS8qLDmbLjAeyVDf9zNQiqcZp6YB6NZmVQJUUxav7s/viewform.

I submitted a minor update that uses the new OHLC data that Kraken offers through their API:

I released a minor update today. It doesn't do much, but it adds support for Windows Phone 8.1. The most noticable change is the live tile, which will be transparent on Windows Phone 8.1 when you are using a background picture:



Other than that, I didn't change much. I updated all the dependencies and the app now uses the new API. It may be a bit faster.

Windows Phone 8.1 will roll out to consumers in the coming months. You can already opt-in for a preview of the update by downloading the 'Preview for developers' app in the store, and opting in for the developer preview. You can then let the phone check for updates, and install them.
