Form's smart swim goggles make you feel like you're truly living in the future. They display your workout and metrics in a little display that lives in the goggle itself, floating right in front of your eye, but not blocking your vision. I tried an earlier version and was impressed.
These smart goggles are on sale right now for $229 instead of the usual $279. They can track your lap times, distance, pace, stroke rate, and more, and display these metrics in front of you as you swim-so no more forgetting which lap you're on. They have a heart rate monitor built in, and 14 hours of battery life. If you pair the goggles with a Garmin or Apple watch, you can even get pace and distance data for open water swims.
FORM Smart Swim 2 - Goggles $229.00 at Amazon
$279.00 Save $50.00 Get Deal 
Get Deal $229.00 at Amazon $279.00 Save $50.00 No subscription is required for the goggles' basic features, but there is (of course) a premium subscription that includes a bunch of extras. For $9.99 per month, you get access to a huge library of workouts and training plans, and there's even a feature where you can take a photo of a written training plan-something handed to you by a coach, perhaps-and turn that into a digital workout in the Form app.
There's also a premium feature called HeadCoach, which detects your head position and uses that to give you technique cues; and SwimStraight, which does what it sounds like-provides a compass for open water swims so you don't veer off course.
