What if Nokia would offer an aggregate service which would combine all tracking services?

I've mentioned multiple times that popular SportsTracker will be introduced way or another in near future. I started thinking what if it would contain a feature which would allow users upload their information from other tracking services also?

I strongly believe that different tracking services will become more and more popular. I've been using SportsTracker for quite some time and report most of my sport activities. It is convinient, if you go jogging, you just carry your phone and it shows distance, your route etc. If you go to play football, you can report the time and date. Phone is always with you, so you don't need to log-in to computer to report these things. If you are using some heart rate monitoring, e.g. from Polar, you could upload this information after you've sent it to Polar's Personal Trainer.

You can ask why would users want to use SportsTracker if they are using Runkeeper on their iPhone? My answer is "their friends". It is common situation that I'm using SportsTracker, some of my friends are using Runkeeper, and some are using Polar's Personal Trainer etc. If there would be an easy way for aggregating this information, I bet that kind of service would have lots of users.

Now you ask why Nokia would do something like that? My answer is "to sell more phones and make profit". If an iPhone user is using already Nokia's popular service, he might choose Nokia phone next time. Services are, after all, one of the main focus area for Nokia.

There is a Finnish start-up called Heiaheia, which tries to aggregate different activities, but does this manually. I mean user needs to login, type his/her activity to service etc. This manual part is quite cumbersome and I keep wondering why would I type these things because they are already in my phone, device, or other service.

This kind of service doesn't need to focused on tracking sports, but it can be used for tracking your everyday life. You could track your holiday route, take pictures and it would be straight-away available for your friends. If you have old parents, you could see where they are at or where they are going. Of course there are lots of security and other issues, but I believe they could be handled.

What do you think, would this kind of service be a hit?
