After more than a year of stopping app development strongly contemplating to restart again. Although time is still a limiting factor I restarted some learning by doing again. Now on Xcode 4.2, and following the Stanford training (via iTunes U) on software development for the iPhone and iPad. Did not buy an iOS (nor Mac) developer license. So to start, I now write an application for the Mac (and porting the training examples from iOS iPhone/iPad to Mac OS). My 1st target is now an application for the Mac: a simple Reverse Polish Notation (RPN) Calculator. I have updloaded the code to Github on: https://github.com/HansQ4/RPNcalculator
Just got reminded by Apple to renew my iPhone Developer Program. Time to give it some thoughts. An invest of the iPhone developer program 79Euro, 2 books each 30Euro’s a total invest of 139Euro and not forgetting the time invested to get my 1st application JuiceLevel developped and launched in Apple’s App Store it’s time for some reflection.
And the earnings? Well via the pay-per-click advertisements I earned $11.69 over the last 11months. Mmm, that does not sound like a very good business case. At this speed the ROI will be around 15years!
But it was fun to do and offcourse by no means had the intention making money with it. However now I need to decide again on an invest of 79Euro I decided to stop here, well at least for the moment. I just have not enough time to do some real development. For now. I might reconsider later again.
So go and download JuiceLevel, it will become a collectors item, in some 2-3 weeks it will disappear from the App Store (sniff!). And keep clikcing the Ad’s. Perhaps that will close the business case after all.
Just upgraded to Worpress 3.0. But forgot to switch off all active plugins, which was offcourse one of the instructions, but who reads these! That left me with an empty webpage. Oeps. Also the admin page was not functioning anymore. Oeps again.
But got rescued by this which helped me out by deactivating all plugins straight in the MySQL database. And that worked! After which I switched on the plugins one by one again.
In short query for “active_plugins” in the “wp_options” table and remove the value string (save somewhere local first i would suggest, just in case). And then active your plugins one by one again, via the regular Admin interface.
SELECT * FROM wp_options WHERE option_name = 'active_plugins';
Included the numbers up to and including February 2010. In total 803 downloads have been done worldwide of which 98 in the Netherlands.
Over 700 downloads and still every day downloads are done. JuiceLevel have been downloaded in over 30 countries. US, France, England and Netherlands are the top 4 countries. JuiceLevel can be found here
Installed the SDK 3.2 Beta version. And indeed now its possible to also develop iPad applications. It also includes an iPad simulator. Although the window of that simulator is called “iPhone Simulator” which it in essence is. I.e. the iPad runs on a iPhone based OS.
Started to develop a new application for the iPhone. But this time supported by a Mac-OSX companion. Cannot tell much about it yet, but targetting to have it released at the end of this year (2009). Stay tunned.
JuiceLevel version 1.0.2 is now available at the app store. Go an update your version!
A new release is under development. Mainly some code cleanups and some small feature updates are foreseen. Most important one is that this release shall add a config setting so that the user can set the boundaries at which the background colors will change.
Version 1.0.0 of the JuiceLevel App is released. JuiceLevel is available in version 1.0 since August 7, 2009. Some minor updates to be expected and to be released in v1.0.2 in the next few weeks. JuiceLevel is a simple application that presents the remaining battery capacity and status. Any remarks and/or suggestions are welcomed. Just drop me a comment.
