Add Pre-loaded training plans with schedules and audio cues to direct your training
I have been using both Runkeeper and Strava for the past couple of years.
Strava is, by far the better app in terms of stability. That's why, I use it, just in case Runkeeper either crashes or some part of it fails to work. So I would really love to migrate completely to Strava.
But Runkeeper has a feature that I just can't leave behind. Pre-loaded training plans, with schedules and audio cues to direct your training runs. This is so dang useful. I don't have to keep looking at my watch when I am doing intervals, for example. It gives you cues to run fast, steady, slow and when to start and when to stop.
And it also has a feature to create a custom training plan with audio cues. I can play around with the length of intervals (time or distance), the intensity, etc.
From a technological stand point, I wouldn't think it'd be too hard to do, since you already have an audio cue feature.
Please get this feature on your app. I would switch over in a heart beat.
