Yes! But after payment you must receive a download link, somehow. Need to think about the easiest way to do this.

Hmm, sounds good. However, I'm dreaming about more specific store (where you can search apps for specific platform and see featuread app, etc)
By the way, can you sell Blackberry apps at your site? And what kind of revenue you can pay? I have an app for sale, just check my signature.

I've just read this https://en.bitcoin.it/wiki/BIP_0021 - it makes sense. Thank you!

After doing some researches, there are two things that make me sad, a little bit:
1. Looks like Apple is clamping down any sales outside of their store.
2. There is a still big risk to host apps with viruses and trojans. At least in the beginning.

Ok, I will try to summarize all gathered facts and think about realization.

Well... yes, if you need to send money to specific address each time you purchase an app, it could be rather long procedure, due to transaction confirmations.

The most obvious and easy-to-do way is to send btc to your account at app store and spend them later.

The other way is to reserve money in your bitcoin wallet and issue a bill at the end of the month, but as far as I know, there is no such functionality in Bitcoin client, isn't it?


Me too. Of course one or two men is not enough for such a large and complicated project. So I want to discuss about it a little, about risks and opportunities, and then gather a team of interested people, who knows.

What do you mean under this advantages? Can you give a more detailed view? Now I see only three advantages:
1) As far as I know BTC payments are tax-free
2) You can use one site with similar interface to buy apps for all of your devices
3) In general, I think this is an opportunity to develop Bitcoin economy further. Now the large amount of bitcoin-projects is about speculation, mining etc. but not about a real business, it would have a negative consequences

Maybe this theme was already discussed on the forum, but I couldn't find anything similar.

I think it would be cool if we could use global market where we could buy mobile/tablet/etc apps for many widely known platforms (iOS, Android, Blackberry etc.) and pay with BTC.

So, I've got some questions:
1) Is someone interested in that?
2) Are there any major companies (Google, Apple, RIM) who made any researches into this? I guess the answer is no, but why?
3) Is it legal?

Zhou, please describe me this situation. Is it just me or a bug?
Yesterday I decided to buy 528.2515 BTC with a market-order. While order was executing the price rose up a bit and I could buy only 500 BTC. Now my open positions looks like this:


and my last order history row looks like:

That's ok. But let's do some calculations: 500 (BTC I bought) *4.9521 (base price of the order) =2476.05

My account info looks like this:

1042.54 (my margin balance) *2.5 (leverage) = 2606.35

So, I expected to see tradable balance around 130.3 (2606.35-2476.05), but not 53.21

No, there is no authentication using an API key, as far as I know. You must enter your username/password in dialog and this app performs standard basic HTTP authentication (like if you're going to access API from browser)

I'm not affiliated with Bitcoinica, I've just used their API and created a small lightweight app, which should be more comfortable for trading on mobile devices then their main website, I hope.

Hi,

I have made a Bitcoinica client for mobile devices. Now it's available only for Blackberry devices, but I hope I can port it to other mobile platforms if you find it useful.

Description, links, screenshots - all is here

Hello.

I made a Bitcoinica client for mobile devices. I hope you found it rather comfortable for mobile devices.

At this moment I made it only for Blackberry platform, but I hope I can port it to other platforms (iOS, Android, etc) if you find this application useful.

Purchase from Blackberry appworld

Update: Now available on CoinDL too. Purchase from CoinDL

Yeah, it's not free, because I've spend some time to develop it, and because you can earn money with this app, so don't be stingy

Here is the detailed description (what you CAN do, and what you CAN'T) and there is also some screenshots:

With this application you can:
     * Trade with all orders types currently provided by Bitcoinica (Market, Stop, Limit, Trailing Stop)
     * View ticker information
     * View your active positions and active orders
     * View your account statistics (USD and BTC Balance, Unrealized P/L and Swap, Net value, Maintenance value)
     * View your order history
     * Information about account statistics, ticker, active positions and orders is automatically updated every 30 seconds

Current limitations (you CAN'T do this yet, and you need to use website):
     * Withdraw or deposit money from/to Bitcoinica
     * View charts
     * Make an exchange
     * Edit your account settings (leverage, username, email, etc.)
     * Set up email notification for your active orders

For any questions, feedback and bug reports please use contact form on my homepage.
   
Screenshots:

Ok, I'll try this. Thanks for your feedback!

By the way, I'm developing a mobile trading app for Bitcoinica, primarily for my own needs, but I wonder if anybody also interested in this too.

Hello, Zhou!
I've found a bug in API. Try to get active orders by link:
https://www.bitcoinica.com/api/orders/active.json
And you'll see that field "created_at" is changing randomly (or almost randomly, not sure about this). For example:
"2012-01-18T13:21:47+08:00"
"2012-01-18T06:21:47+01:00"
"2012-01-18T09:21:47+04:00"
...

Greetings.
I wonder if there any application selling site (like Android market, Apple App store, etc) where you can pay with bitcoins for apps?

If there's no one, it would be a great to build such market (not bounded to any specific platform), where you can buy apps for any platforms and pay with bitcoins only. Don't you think so?

Hello. I'm developing lightweight mobile client for Bitcoinica trading platform, primarily for my own needs. But I hope it will be worth for somebody else.
