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.

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. 

Looking for something else? Retailers like Walmart, Best Buy, and Home Depot have Prime Day competition sales that are especially useful if you don’t have Amazon Prime.

• Walmart’s Prime Day competition sale runs through Sunday, July 13 and includes deals up to 50% off. It’s an especially good option if you have Walmart+. 

• Best Buy’s Prime Day competition sale, “Black Friday in July,” runs through Sunday, July 13 and has some of the best tech sales online. It’s an especially good option if you’re a My Best Buy “Plus” or “Total” member.
