Doodlr is my flagship mobile project that lets you create greeting cards and send them via text or email from your Android phone.
Not exactly an original idea admittedly, but browsing the Market, it seems like a popular need.
And, possibly more importantly, I think the apps already in this space are poorly executed. Really, really poor. And the most popular achieve approx ~500,000 downloads.
Here's a video that can explain more ( you may want to turn down the sound! )
Its also available on the Amazon marketplace : http://www.amazon.com/gp/product/B006OIK6JC
Doodlr will grow - I'll be hoping to make money out of it in the near future.
Stay posted for some updates.
