This provides a simple graphical tool for scuba divers calculating maximum operating depth. It provides both iphone and Apple Watch versions. It's important to remember that while scuba diving, it is always recommended to double check your calculations with reference to the relevant diver tables. While this app may prove useful, it's no substitute for using your own brain and being fully aware of the dangers of scuba diving. Enjoy !

Freediving for Apple Watch — snorkeling and spearfishing too. Blue Infinity records your dives on Apple Watch and shows you the detail on iPhone. Three modes, each built for the way you dive. OPEN WATER • Depth and dive time on the way down; your last dive's depth and time when you surface • Surface and session timers, heart rate and water temperature • Your route on a map, and a fly-through that follows it dive by dive POOL SESSIONS • Swim your reps — each dynamic is found for you, with its distance and dive time • Start and end a static with a turn of the crown • Tag disciplines (STA, DYN, DNF, DYNB) and set your pool length LINE DIVES • Live depth, dive time and ascent and descent speed • A tap at 16 ft on the way down, and a recovery countdown between dives ON IPHONE • Depth and heart rate charted together, for every dive in a session • Notes, disciplines, and trimming a session or a single dive to where it really started and ended • Haptics you can set for each mode Your dives are saved to Apple Health and your iCloud account. There's no account to create. Depth currently reads to 20 ft — the limit Apple sets for apps like ours. We've applied for access to deeper water. Works with Apple Watch Ultra and Apple Watch Series 10 or later. Recording on the Watch is free. The dive detail on iPhone is free for your first 5 dives, then by subscription.
