I use Form goggles. They are aimed at competitive swimmers, but all I care about is heart rate. I had previously used an Apple Watch but stopping at the end of a lap (or after the swim) and looking at your watch kinda defeats the purpose.
With Form I see my heart rate in real time 100% of the time. I was worried I'd have a problem being near sighted but it really does look like the data is being projected 10 feet in front of me. It's a neat trick - my brain actually thinks that when I exhale the bubbles are in-between me and the projection, even though I know it obviously isn't.
My only complaint is that every single forking time I open the app it tries to upsell me on their structured training program for a monthly fee. Literally every time - I open the app and have to tap 'no thanks' before I can use it!
While I have your ear, what is the actual "goggle" performance like? These came up as the highest-end option when I was looking for a new pair. I have constant problems with every pair with seal, fogging and eventually degradation of the materials. My most recent speedo goggles see-through seal has degraded to the horrible yellow plastic, even inside a case, in a bag, in a cupboard.
It’s very good. I’ve only had them since the first week of August so I can’t speak to their longevity. But they’re comfortable (I do up to 90 minutes), stay on in turns, don’t leak or fog. They project the HUD display onto this little screen on one of the Goggles (you can make it either left or right). Because of that they say to not do the typical thing that every swimmer does and spit in the goggles and rub it in. They say to never touch the goggle interior and just trust the anti fog coating.
