I was waiting for such an app! Will try it.
Thanks for the announcement.

EDIT
Just saw that it only supports USD. Will you add other currencies as well? And more importantly, will it allow to use MtGox as a mobile wallet? This would be really convenient as there is no mobile wallet for windows phone.

[Lotus]

Yes. I am planning to add additional currencies to the app. EUR was next on my the list, but feel free to suggest other currencies. I do, however, need beta testers that use each currency I implement to verify the functionality before it's released to the public.
As far as MtGox mobile wallet, are you referring to making withdrawals and deposits to BTC addresses? This is actually pretty simple to implement, but I believe it would be a security concern having an API key on the phone with the ability to transfer funds out of your account (especially for people that have a lot of active trading). Instead I was planning on adding the ability to transact from the app either by generating/importing addresses locally or by integrating with BlockChain.info instead of sending BTC out of their main MtGox account.

I am curious to know how other people would feel about this. If people think the security concern is minor, I can implement both.

I go for EUR I can testuse if you like and give you feedback. The problem I had so far was that I couldn't copy paste the API key on my phone and typing it manually it is quite tedious. Could you do something about that?
You could testuse our site https://www.bitbond.net/ in turn as a buyer btw. You can see the test projects from my co-founder Jürgen which will 100% be repaid so there is no risk. Currently we gather feedback about the look and feel of our site.

As far as MtGox mobile wallet, are you referring to making withdrawals and deposits to BTC addresses?

Yes, I was referring to withdrawals and deposits. Beside the security issues the other thing is that it only really makes sense if you could scan a QR code to make payments. Anyway, if it's easy to implement I'd give it a try. It's a trade off between convenience and security...

Great, I'll PM you about testing. For Keys, I would typically use SkyDrive to copy them to the phone and just copy 'n' paste in the boxes (make sure when pasting you include the == signs at the end). I didn't bother putting tips about it because I'm updating it to use QR codes anyway.

Beside the security issues the other thing is that it only really makes sense if you could scan a QR code to make payments

Of course, nobody is expected to type down BTC addresses by hand. There will be a few additional options to support certain scenarios, but QR rendeing & scanning will be the first to get implemented.

[Lotus]

Version 1.1.0.0 has now been certified and published to 44 additional stores/countries.
No new features in this version, but a number of small bug fixes.

[Lotus]

Version 1.2.0.0 has been released to the store. It brings euro trading to the application as well as a larger number of bug fixes and tweaks.
You can now send feedback right from the app, so if you feel something is missing or could be better, don't hesitate to send your suggestions.

Changes in version 1.2.0.0:
* Major internal restructuring to improve robustness
* Added the option to send feedback emails from the app
* Support for EUR currency
* Ability to switch between multiple currencies for trades, history, and pending orders
* Support for Non-US locales
* Reliability fixes
* Better error messages

Good job!

[Lotus]

Good job!

Thanks for your help

Very nice! You should add a wallet feature in it so people can send/receive on the go.

Very nice! You should add a wallet feature in it so people can send/receive on the go.

That's already on my list. It's at third place right after adding adding additional exchanges & reading QR codes (to read the addresses).

I was going to implement this through BlockChain. Is that what you had in mind or were you thinking more along the lines of really isolated wallet on the phone?

[Lotus]

Version 1.3.0.0 has just been released to the store.

This brings CampBX trading, QR scanning, and a bunch of bug fixes to the app. I am updating the original post with more details.

Let me know how you like it.

[Lotus]

Minor update to version 1.3.1.0 fixes Live tile bugs. The live tiles should now work in all currencies and using the correct exchange.

[Fugger]

The QR scanning is great! Saves a lot of time. Live tile works well, too.

History wouldn't show in the current version. It had already worked before.

[Lotus]

Hmm... I thought I already fixed the history bug in the current version. It should display fine if you manually push the refresh button. If not, then it's a new bug I need to investigate.

[Lotus]

Looks like CampBX is currently inaccessible through the API at this time as CloudFlare is intercepting the requests. We are aware of this and there is no need to report this problem to us at this time. Could be a result of the current rush. I will contact CampBX if this persists for more than a few days.

[Lotus]

CampBX fixed the problem. Everything should be working again now.

[Lotus]

Version 1.4.0.0 has been released with experimental support for Coinbase (an update for that exchange is currently in testing and should be coming out in about a week).
Also added the ability to place market orders.

[Lotus]

Version 1.4.1.0 has been released. Now with support for OAuth for Coinbase and a bunch of bug fixes.

Coming up next: BTC-E integration. If you're interested in helping out, we need more beta testers that trade on BTC-E.

[Lotus]

Version 1.4.2.0 out with a few quick fixes including broken Bitcoin Can ticker.

[Lotus]

Version 2.0.0.0 has been released. Now with a new dashboard and support for BTC-E.

[Lotus]

Multiple versions released since my last update.

Version 2.0.2.1 is out with the following changes:
* Bit2C Ticker.
* OKCoin Ticker.
* Bitstamp trade support.
* Bitfinex Ticker.
* BTC-E trade support (we had only ticker previously)

Lots of fixes has gone in. Also the app is no longer compatible with Windows Phone 7 devices (it was never intentionally supported in the first place).
