Adidas Runtastic
adidas Running app
Best for runners who are motivated by a shared goal rather than a coach. The app's draw is its global challenges and virtual races, which give a reason to log another run in a slow month, and it also tracks walking, cycling and more than 90 other sports, so a mixed week of training stays in one place.
Personalized training plans are available for runners of all levels, and the app syncs with common wearables. A paid Premium subscription unlocks the extras, and its price varies by country, so check the in-app price before subscribing.
