As a runner/triathlete, this is pretty useless to me. As another commenter describes - we prefer real-time time series data. TrainingPeaks captures everything I could think of.
Seems like it might be useful for lifting though. At the same time, I don't know that the "common format" problem is really a problem. When I've logged lifting workouts, I just used the app for the program I was on (Starting Strength). Maybe more serious lifters feel differently...
Yeah, for things that are measured solely in time, Traindown isn’t a good fit.
For the question of the usefulness of portability, let’s imagine StrongLifts uses Traindown and you have the ability to access that data directly as Traindown files.
Now imagine someone has developed an analytics package that slurps your owned data and that allows you to easily spot patterns that can improve your results. You could use that immediately and find value. You would not need to export whatever mess and try to make it work assuming they even let you do that.
That’s the idea, anyhow. I feel very strongly that YOU should own YOUR DATA and applications should provide value ON TOP of your data. This provides you true freedom of choice.
