If you're looking for a device to track your fitness, alert you to incoming messages and occasionally let you buy stuff with a scan or a tap, there's no shortage of computerized wristwatches to choose from.
Over the past several months, Associated Press technology writer Anick Jesdanun tested numerous smartwatches for iPhones and Android devices, along with fitness trackers that have some smarts. Jesdanun even wore six watches at once during three marathons over the past month, courting both ridicule and some lousy times. (The author blamed the extra weight.)
Smartwatches and fitness trackers are relatively early devices with a lot of growing up still to do. Temper your expectations, and you might be pleasantly surprised. Just don't go in expecting magic, because that's a recipe for disappointment.
Your options will vary depending on whether you use an iPhone or Android, as most of these watches require a companion phone for their smarts. There are also big differences between all-in-one smartwatches and simpler gadgets that primarily track fitness.
