Blue Infinity Freediving Watch vs ShalloWeDive

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.

Track your depth at a glance — right on your wrist, right underwater. ShalloWeDive is a real-time depth tracker built for shallow water — down to about 6 meters — using the Apple Watch depth sensor, with an iPhone companion for your dive logbook and dry-land breath-hold training. Snorkeling, freediving, spearfishing, or a mermaid set: see your depth, water temperature, heart rate, and dive time the moment you go under. No phone signal, no internet, no subscription — just your wrist and the water. Color-coded safety zones change as you descend — safe (teal), caution (yellow), danger (orange) — so you always know where you are without looking away from the water. How Far You Actually Swam Dynamic apnea is scored in distance, yet no dive computer measures it. Now your wrist does: the wall turns of a pool swim are counted from the watch's motion, and the rest screen shows the swim's distance — turns times the pool length plus the last partial length — marked "~" as the estimate it is. Correct it on your phone; the original stays beside your correction. The Clocks a Dive Computer Has — On Your Wrist, and Your Buddy's Static, dynamic, tables, interval, stopwatch and surface interval, all on the watch, all staying lit through Water Lock and wrist-down: - Static: taps before, at and after your target; the hold starts when your wrist goes under and ends on the Action button — or when your wrist comes out - Dynamic: the swim ends when you surface and the rest counts from that instant — shrinking-rest CO₂ sets or fixed-interval departures - Your phone's tables, run in the water: each hold a target, each rest from the moment you came up - As breath-holder or buddy: one program, timed by the water on one wrist and by a tap on the other; the phone shows both records side by side Breath-hold in water is done only with a trained buddy watching, never alone. Train Your Breath-Hold — On Dry Land The iPhone companion also coaches classic apnea tables, no watch required: - CO₂ table, O₂ table, or a single static hold — or build a table of your own - Every round runs a recovery first, then the hold, so you always start rested - Voice announcements pace each phase, even with the phone locked - Every session is recorded, round by round Dive Under Your Own Discipline Choose your discipline before the session and the watch applies its timing: Freedive — one deliberate descent per surfacing, with a surface rest timer between dives; Mermaid — a rehearsal set of short, shallow immersions inside a fixed window, with targets for depth, bottom time, and dive count. On Your Watch - Real-time depth and water temperature from the built-in depth sensor - Heart rate monitoring during every dive - Multi-dive session tracking with automatic dive counting - Descent and ascent times for every dive within the sensor's range - A dive logbook on your watch, saved between sessions The iPhone Companion Review your whole logbook on a bigger screen: - Dives group into outings, with search by site, buddy, tag, or note - Add the dive site, buddy, gear, notes, and a personal rating - Dives sync from your watch automatically — or all at once, on demand Your watch and iPhone connect directly, on-device — no account, no server, and your logbook leaves only when you share it. Beyond the Measurement Range The depth sensor is built for about 6 meters. Past that, "No Limit" mode silences the depth alerts and shows a calm "beyond range" readout — and the logbook records the dive honestly as "6 m+", with no invented maximum or split. Private by Design All data stays on your devices. No account. No server. No tracking. No ads. Diving requires an Apple Watch with a depth sensor (Ultra, Ultra 2, Series 10, or later); breath-hold training runs on any iPhone. The two sync directly, no internet needed. ShalloWeDive is a reference tool. It does not replace certified equipment, proper training, or safe diving practices. Always dive within your personal limits.
