Smart wearables are incredibly useful when it comes to outdoor workouts, especially in situations where you don't want to be carrying your mobile phone.

Fitness apps can take advantage of offline maps to provide users with navigation features on smartwatches. The problem is, how can the offline maps generated on a fitness app be synced to a smartwatch?
