Blue Infinity Freediving Watch vs Dive Compass Simulator

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.

Dive Compass Simulator is a training app designed to help divers practice the use of underwater compasses in a realistic and controlled environment. Underwater compasses behave differently from phone or land compasses. They require correct alignment, stable positioning, and a flat orientation to function accurately. These skills often take time and repetition to develop. This app allows divers to practice these skills on land, helping build confidence and muscle memory before entering the water. Key Features • Realistic simulation of underwater compass behavior • Tilt detection with visual warnings when the device is not flat • Heading and reciprocal heading practice • Magnetic interference detection • Clear visual feedback for correct compass handling Who This App Is For • Student divers preparing for navigation exercises • Certified divers who want to improve navigation accuracy • Dive instructors using it as a supplementary training tool • Anyone interested in practicing underwater navigation techniques Practice Before You Dive Limited pool and open-water time makes repetition difficult. This simulator provides an easy way to practice compass handling anytime, helping divers feel more prepared and confident underwater. Note This app is a training simulator and does not replace formal dive instruction or certified dive equipment.
