The Apple Watch is "ok" for running. Especially with the sports rubber band. Activity tracking like walking or cooking, gardening will also show good to excellent readings. But you should try it in cycling on roads. Pebble stones, bumps, traffic, sudden stops. Readings are inaccurate, especially if you are reading fast (!= commuting) The worst inaccuracies I saw was in martial arts and bootcamps. Those are when you move your hands in unpredictable speed and directions. I think readings would also be quite inaccurate in most racquet sports. I'm not sure I have seen any reviews about the Apple Watch in these conditions.
