I've been working with Soo Ling Lim recently on a computational model of the App Store. It's partly made possible by my experiences with the app iStethoscope Pro which has produced a lot of fascinating data. The work has just been featured in a magazine called SIGEVO, with the front cover showing one of our viral networks, see below. We're continuing the work by interviewing large numbers of people about their usage of App Stores. Please fill in the survey here and we will use your information to make our model even more accurate: http://tinyurl.com/mobi-user

A while ago I was interviewed for an article in the Polish magazine Focus. The writer just got in touch and gave me a link - looks like an interesting piece on mobile devices and health from what I can glean using Google Translate. If you can read it, the article is online here: http://www.focus.pl/technika/zobacz/publikacje/terapia-komorkowa/

Another week and another mention in New Scientist. After the review for my latest book Digitized last week, the work of myself and colleague Soo Ling Lim is featured as lead technology story this week. Paul Marks wrote a nice story describing our ALife model AppEco. He focusses on our forthcoming paper for GECCO 2012, where we explore which app developer strategies might be more successful than others. If you're wondering what the answer is - I'm afraid it depends on what everyone else is doing at the time... But in general the app store settles down into a stable state all by itself, with the more dodgy strategies (copying the successful apps of others, or milking a single idea endlessly) tend to be in the minority compared to more imaginative strategies (optimizing good ideas or innovating new concepts). So in general we found that it's better to innovate or optimize than be a milker or a copycat. Which is just as well, because Apple specifically has clauses in the developer agreement which are designed to discourage milkers and copycats.

It's an interesting piece of work and I enjoyed helping Soo Ling create the model. We're still working on it, and are looking at the effects of publicity strategies, different charts, and all kinds of other things...

The article is available online here, or below if you want a quick view.

The founder of wooshers, the Pulsatile tinnitus forum has been in touch again. It seems this time someone may have successfully used my iOS app iStethoscope Pro to record the elusive sound of her condition. This is what she said:

One of our group members has had success listening to the objective pulsatile tinnitus with your iStethoscope App. She gave me permission to share her experience with you, since I told her I thought you'd be interested!

She's been diagnosed with superior canal dehiscence and bilateral sigmoid sinus diverticulum. She has already had surgery on one side to correct it, and is awaiting surgery on the other side. Anyway, here is the post she shared on our Facebook page. I am fascinated by this and hope to again ask others --particularly those with a similar diagnosis-- if they too can hear their whoosh with the app. She is thrilled that she can now share the actual audio sound with her doctors and everyone. The doctor who performed the surgery --Dr David Eisenman in Baltimore-- is a doctor I've been in touch with for several years and he has corrected many patients' symptoms.

Do you have an iphone? The app is way cool! the Microphone at the bottom of the phone is used as the "stethoscope" you put earbud style headphones in and wear them. Then you open the app and crank the volume...be careful, just like a real steth if youve ever used one, it's LOUD...dont talk into it lol. You can listen to your heart with it by firmly pressing the bottom of the phone right where a stethoscope goes...same thing. Put it over you belly, you will hear your bowel. Put it one the sides of your ribcageor back, and you hear you lungs. Putting it all over different pulses in the body, I found my venous hum...which i already knew i had even though the doctors coudnt hear it. Right above the clavicles...I have it both sides and it goes away with certain head positions.

The use of smartphones for mobile sensing is really starting to take off. One group in EPFL uses an iphone coupled with several adhesive ECG sensors to enable patients to monitor their own hearts. Software on the phone can automatically detect if there may be a problem and alert the doctors. It's an ECG version of the kind of technology we're developing for iStethoscope. CNN asked me to comment on the work; you can read about it here:
