I think i got my HTC Mozart 7 some time in March 2011. After using it for a week or two, i registered myself as a Developer and started writing my first app Scribble in April. I think I spend 2 weeks writing it.
This was the first time i was coding Silverlight and its been fun.
Scribble: Initial effort – 2 weeks. It was my first try at Silverlight app and it was a simple drawing app – having used the word simple, it did a lot of things – use photochooser task, save to Photo Library etc. It even supported multi-touch – It was a great learning experience.
Alarm Clock: I spent a good 2 / 3 weeks writing this and yes i love this app – I use it as my Alarm clock – especially since Mango update as i can now have alarm without app running 🙂 –
LearnToWrite: 1 week – this was the simplest app i have written. Just features simple alphabets and numbers.
Sliding Keyboard: I wrote the above 3 apps trying not to write Sliding Keyboard. I just couldn’t get it out of my head and no matter how hard i thought, i wouldn’t figure out how i would achieve it. However I got it running in 2 weeks. And it went live in June 2011. Publishing v1.0 was a big mistake – it got slated on so many levels. Over the next couple of months, i cursed myself enough number of times. I have spend weeks and weeks since initial release – now it stands at version 3.2. It has taught me the most – it taught me humility – i am good at what i do and i realised that customer doesn’t care about how hard you are trying – they just want the product to work. I also learned that no one reads the description 🙂
The total downloads stand at 22,822 – Paid downloads are just over 1216. Here’s the download chart
I think it has been a very trying year – as a WP7 user I love the phone.
As a developer – I have mixed feelings – I love and hate the fact that API is restrictive. Microsoft have been fantastic in testing the apps – Everything has been as smooth – they test the apps better than i ever do. Thank you.
As of 2012, I am writing a couple of apps. Let’s see what this year holds.

Hi Dave,
Sounds like 2011 has been a mixed year for you too. Still 22,000+ downloads and 1216 paid is definitely something to build on. Good luck in 2012.

yes it has been a mixed year.. though i only write mobile apps in my free time 🙂 i would be starving if this was a real full time job.
