New Fitness App Ideas? – Free Kit for Good Responses

I am beginning to develop a phone app aimed at the fitness market, which will help users to maintain, improve and measure their fitness. It will take data from a wireless heart rate monitor (chest strap), the phone’s GPS sensor and from user input (e.g. weight).

Of course this can already be done (e.g. Runkeeper, CardioTrainer, iFitness) and the app will include all of the features and analysis present in these apps. However, I am also looking to include novel features that are not available elsewhere – which is where you can help!

What I would like to know is the kind of novel features that you would find useful in such an app. Are there things like VO2max and EPOC which could be calculated and which you would find useful? I have access to expertise in signal analysis and machine learning – is there any information that might be extracted from the sensor data which you might find useful, e.g. breathing rate, a measure of the user’s level of fitness (e.g. Conconi test), a measure of when exercise intensity is too high?

Thanks for your time – when (if!) the product comes to market I will send each of you who provides useful feedback with a free sensor/app as an expression of my gratitude.
Thanks very much,
Tom

hi

not really an idea of a functionality, but top of my list of todo would be that
your app can read ant type info .. either HR chest strap or bike cadence sensor .. that would be nice.
else,
a climbing or descending real time velocity would be a nice info to display

cheers

Thanks for the feedback - will keep you updated on progress.
