What Smartwatch apps do you see yourselves using?

An anonymous reader writes: It's official. The Smartphone wars have begun, with Apple's announcement of the Apple Watch adding a contender to the race that has the likes of the Pebble watch and Moto 360. My doubts about wanting one were put to rest when I learned of the health-related features. Smartwatches will be able to track your movements and pulse rate, calculate how many calories you burn, coach you continuously to improve your fitness.

If you do get one, though, then what other apps or functions do you imagine yourself benefiting from? Assuming that Slashdot is well-read by the app developer community, your wish might come true.
