I suggest we make a blog post about this, I think the apps you listed already enumerate the most popular ones, though we might have to look at some platform specific ones (like Nike+)
We should start with listing all the features we want to compare:
- Price
- Mobile and/or Web App available
- Major features
- Training programs
- GPS tracking
- Diet/calorie counter
- Social sharing
- Accessories (required or optional)
- Heart rate monitor
- Accelerometer
- GPS-receiver
Given that not everybody can try out every app, we should get several users to pitch in to help review their favorite app. I guess its better to focus on quality than quantity, besides we can always post an updated version (like on a monthly or quarterly basis) that incorporates new apps.
Here's a list of apps and the users that want to review them:
Accessories:
We also have a budget to sponsor apps or products that cost some money, like Runkeeper Pro or using an app with a HR monitor or FitBit. I'd suggest we couple those with a general review we can post on the blog as well.
This might take us a few weeks to compile, but I'm sure we can get cracking at it. I made this post CW so anyone who wants to add features or want to review an app, feel free to edit it.
