No indoor?

Cannot be used for indoor pool

Used to work

The app has started asking me to log into my Apple account while I am swimming in the ocean. Of course it's pretty much impossible to do that in the open water. It's too wet, duh; fingers are gloved or too cold; and trying to read the watch screen through swim goggles in rough water--you get the picture. Then, I can't actually use the app to tell me how long I have been swimming, or how far. Of course I have searched the app itself, and Watch settings, to prevent this. No luck. Suggestions????

Very happy with the app

Very pleased with the app and support responsiveness (contacted once for a feature request and once for a minor problem). Touch screens can be a bit persnickety but that is not the app’s issue to deal with). I’m a happy customer

Best I’ve found yet

Does exactly what it says it does and very well. Lovely interface and health integration. Had a couple of issues that were fixed and very happy with it. Beats the Apple Workout Open Swim that doesn’t work for me and this works 100%.

Did not do what advertised

I purchased this app with the pro version for the advertised water temperature feature. I was very excited to see what the actual water temperature was where I swim. No reading was done. This is no better than the workout app that comes free on my phone. I tried to use the support feature and it did not work. Maybe this will get a response?

I got a response from the developer: turns out many features advertised do not work with many watches.

Temperature reading only works on watches with a water temperature sensor. Those watches are:

Apple Watch Ultra
Apple Watch Ultra 2
Apple Watch Series 10
