Most of us like to blast a collection of inspirational tunes during a workout, and with its latest iOS update, RunKeeper is making that a bit easier. Runners who also have a Spotify premium subscription can now access saved playlists inside the fitness app. You'll need to connect the two services first, but once you do, swiping over to your fine-tuned collections and suggested workout playlists is pretty straightforward. Unfortunately, there's no mention of Android users getting the integration as part of future updates. However, RunKeeper says this is the beginning of its foray into music, so perhaps those upcoming tools will cross over.
