Funny as I had the opposite impression. Collating all the information into one place is more difficult than the effort needed to record the 4-5 different data sets in separate apps.

Case Study:

Location/Running/Walking/Cycling

- I have Garmin 405 watch and all running logs can be exported to TRX files and overlayed on a map to show each session, it records heartrate during the session and calories burned etc.

- I have apps on my phone (some I probably am not aware of!) that can track a huge amount of information when the Garmin is not recording. Steps, location, point in time heartrate records, Time spent in apps which can be grouped into Reading, Watching, Listening etc. If I so wished it can also track sleeping activity.

- Fitbit - tracks all of the above without location or heartrates but good as a general "how active I was today" collection point.

- Heart monitors - single point in time recordings for Glucose. I havent tried HDL/LDL but I assume it is similar? A single scan per day would be enough to trend results over.

So from all of those relatively non invasive (apart from the glucose tests I already log this stuff regularly) data collections I should be able to easily produce something similar to this site right?

Nope. Each one of those devices/apps/whatever has its own data format, its own interval timings (seconds, hours, ticks, epoch, instance etc). To just gather that information into something I can use I would need to write a custom conversion tool to map its data into my own version (canonical). I assume this is what he has done or else some of the data is only skin deep and not interrelated at all (heartrate has no references to location for example and cannot be easily linked without some manual intervention).

I'm guessing (from a somewhat educated position) that that was the hardest problem to fix, and if he has solved it for the apps listed then that is the piece that will be monetized first, after all everyone and their uncle has a fancy UX but data is god.
