I would expect at least some running apps to try and analyze running speeds and give (intelligent) advice, either post-fact ("you have a 4 day gap in your weekly running schedule, this is detrimental to your training", "your speed decreases significantly towards the end of your run, you should try starting at a slower pace", etc.) or during the run ("you should pause now for x minutes", "you should increase your speed", "sprint for 2 minutes" etc.).
- OS: Android (or something that can import data from an Android app)
- No specific requirements as far as the specific advice that is generated, as I have been unable to find any apps at all doing this.
