Any music app that offers off-line play mode. iTunes, Apple Music, Pandora (premium). At the moment Spotify does not allow off-line play mode with Apple Watch, but we expect that to be updates soon.
YES. Audible and Apple Audio Books are both good options. They both enable downloading of your books to the Apple Watch. You can manage the downloaded books from the Apple Watch Audible App or Apple Audio Book App. You can seamlessly continue listening your audio books with Interval. Inside the Apple Watch App you can select which podcasts and how many episodes are downloaded to the Apple Watch.
The Interval comes with built in Surge headphones, micro USB charging cable and 2 styles of earplugs In 5 different sizes.
H2O Audio has developed the app to detect your lap turns and log your swim distances. The Apple's own Lap Swim App does not work when the watch is mounted on your head for audio. And since we have audio available, we can tell you your lap count and distances - without the need of looking at the screen (and the screen is not very easy to use in water anyway). Just got to the Apple App store and look for the My Swim Tracker. It is a free download for your iPhone. When you download the iPhone App - it includes the Watch app that you will need to install from the Apple Watch App.
H2O Audio has been developing products for swimmers since 2003. We are proud of the quality and customer service we offer. If you are not satisfied with the product, you may return the product within 30 day from the date of purchase.
