How does it all work?

In this blog, I explain the process behind my Sudoku Grab app, a solution that uses basic image processing techniques to recognize Sudoku puzzles. This is done by locating the puzzle in an image, turning it back into a square form, segmenting it to find potential numbers, and lastly, recognizing those numbers. This involves simple thresholding techniques, blob extraction algorithm, perspective transform, and a Neural Network for Optical Character Recognition (OCR) to recognize digits from the photograph. I conclude by mentioning the potential for multiple enhancements to this process.

Sales stats update - 5 or 6 months on the app store

Apologies for the radio silence on sales stats for our app, but to be fair, there hasn't been much spark! After the US App Store feature, it was a sliding game down the charts, but still, we average about 10-30 copies daily. We excitedly crossed the 25,000 download mark recently. Oh, and there's a chart you can find below with more deets. A Dutch website brought a brief sales soar, but that's died down now. All told, we've clocked in 25591 paid and 8436 free downloads, the latter gaining a brief spotlight during a celebratory two-week freebie phase. Sure seems...

Sales stats update - Two months on the app store

Another month on the App Store, fellas! Even though our little app met some bumps here and there, it still managed to get quite the spotlight in Europe's 'What we're playing' section, grossing up to 200 daily sales in the UK, 300 globally. Took a hit when we dropped from the featured list, but that was expected, right? Thankfully, other countries picked up the slack! Brought in a new icon and broke into the US market, making a splash in their 'New and Noteworthy' section. Seems like being on the front page or featured list really makes a difference! Despite...

Busy busy

Just landed back home after a couple US trips. It's time to roll up the sleeves and get busy now - have to update instructions for our 1.4 version, which isn't too different from 1.3 but with a few changes. Also, got to start working on 1.5. Let's do this!

A couple of reviews

Our app has finally been reviewed by a couple of sites, namely 148apps and iPhone App Reviews. Unfortunately, our daily downloads in the US are still low, hovering around 10-20, and the app has moved off the front page of the app store in the UK, causing a significant drop in sales. Stay tuned for a detailed update in a couple of weeks. Appreciate all the support and readership.
