App works, but I have suggestions…
The watch app seems to work on the Apple Watch Series 3. The set max depth notification is a plus. I do wish the app could change meters to feet. I also wish the app had the max depth on the current depth screen. * This app will not replace a dive computer since it doesn’t provide decompression stop levels. However for staying above the 30 feet or 9 meters to avoid the bends this app would work, assuming your PADI or SSI certified.
