For those interested, this project has become open source and published on GitHub: https://github.com/rbonestell/myHavelock-AndroidI haven't found much time to maintain it, but would be happy to see new contributors and review pull requests! |

I'm offering a small bounty - I'm not sure how much yet, perhaps 0.5 - 1 BTC - for an Android app widget that displays the following info:
* The current blockchain height
* Minute count since last block
* Total outstanding BTC mined (current formula is easy: 210,000*50 + (nHeight-210,000)*25)
It should look pretty and be open source / public domain. There are plenty of app widgets that show btc/usd price, but I'm more interested in seeing some real time stats about the network at a glance.
Is anyone interested in taking the offer?
This seems pretty easily doable using the blockchain.info API, have you decided what size bounty you're willing to offer? Do you want this published to Google Play, or only just open-sourced so you can compile it yourself? PM'd you. |

Professional applications for banks and financial services are usually free - look at the apps for Lloyds, Barclays, American Express, Bloomberg etc.
Using a freemium or ad-supported model cheapens the user experience and reduces the professionalism of the app. Could you imagine checking out your current account balance on your app, only to have a banner ad for payday loans flashing across the bottom of your screen? Blerg - cheap and nasty.
If you have to charge, I'd suggest somewhere in the region of £1.59/$2.59 - but make it worth it. But, this should really be funded by the group that stands to benefit the most - namely, Havelock. They have just paid the developer 1 BTC, which is a good starting point.
I'd estimate a good app for a flourishing new financial service should net the author in the region of $50,000-$100,000 (I say this because the app for telling you where to stand on the London underground for the quickest exit earned its developer £50,000 - $80,000). A very worthwhile reward for contributing to our growing little ecosystem here.
Thanks for the feedback! My original intention was to release myHavelock free (without ads) and request donations, then eventually extend myHavelock (ultimately) to be a full-featured Havelock Investments client where users must pay to unlock the trading features - otherwise they can only monitor their portfolio. Perhaps I can get away with pricing that functionality in the range you have suggested.  |

Great news. Just please don't make it free. Make it good, and price it at $5 at least.
Out of curiosity, why do you recommend charging? I'm all for earning revenue from my applications but in my experience the ad-based or donation models have been more lucrative. |

myHavelock v1.1 has been promoted from Alpha to Beta this week! I have edited the original post to include a screenshot of the primary new feature: performance and volume charts. Again, to access early alpha and beta versions of myHavelock please join the myHavelock Google+ Group and enroll in early access for the app! This version is expected to be promoted to production early next week. FYI, iOS version coming soon! |

How would you improve the rainbow?
Add more colors, of course.  |

I'm interested in seeing where this goes and have 1 dire request for BitcoinTalk 2.0: Please implement an open API for developers! So much action in the community occurs right here on the site and the only API I could find was this one: http://bitcointalkapi.appspot.com/https://bitcointalk.org/index.php?topic=154131.0While I appreciate the work Logik put into this solution, it never seems to be synchronized with the actual content on the forums. This would make it easier for us (the development community) to incorporate trending news in apps and automate the posting of important information to the site. |

Thank you rbonestell for a great looking easy to use App. Setup took less than a minute. We have been approached by several developers to create different types of Apps to integrate with our platform and we do believe that a good trading app is needed and we are working towards that goal. In the meantime thank you once again rbonestell for taking the time and developing this great App, we know we will use it. https://blockchain.info/tx/e16412743e5ccbca21421ce443cda38742e09d2281550562b01a09974d7b4238Havelock Investments Wow! Thank you so much! Just another reason to be proud to work with Havelock! |

This looks great! Thank you!
Look forward to see the OS version.
Thanks! iOS is next, assuming they even allow me to publish it on the AppStore...  This is great. I just can't believe Havelock (a US$40,000,000 company given all the value they're holding) can't spend 3-4 BTC to get this coded up themselves…
Havelock are kinda triggering my 'scam' alarm a bit...
Yeah, I'd be stoked if they offered to buy it from me! In my experience communicating with them, they are very professional and helpful. However, I see your point in that they haven't made many changes or advanced much technologically in quite some time. Makes me think that there might be something big coming, but I have no data to back that up. |

Hello,
Great job, does it have USD value of the security/portfolio ?
Thanks! No, it does not have the USD value but that's a pretty good idea! |

I have just recently released an Android application for monitoring your Havelock Investments portfolio: https://play.google.com/store/apps/details?id=com.rbonestell.myhavelockIt only requires portfolio read access with an API key generated by your account on HavelockInvestments.com, it cannot perform any other actions on your account.    I'm in the process of adding more functionality, including charts. I also have a small group of beta testers on Google Play providing feedback on new features. If you're interested in joining the beta testers, join the myHavelock Google+ Group then click the "myHavelock Early Access Enrollment on Google Play" on the group page. Right now I'm doing this solely for donations: 1JXgV2fAGyMRfNoLH5U6LL4xLCbXBWn3fF |
