ShalloWeDive

The freediver's logbook that listens, draws and remembers. On your wrist and your iPhone. ShalloWeDive turns an Apple Watch with a depth sensor into a freediver's dive computer for shallow water: live depth, water temperature, heart rate and dive time down to about 6 meters, no phone and no signal needed. And it turns your iPhone into the logbook a dive computer's app would give you: every dive drawn second by second, every day told in your own words. YOUR DAY, WRITTEN UP BY AN AI THAT SPEAKS FREEDIVING Tell the day's page how it went, the way you would tell a buddy. An AI tuned for freedivers writes your words into a clean record: site, buddy, weights, visibility, what you worked on. It understands the words of the sport as you mean them (CWT, FIM, DYN, equalisation, surface interval), asks one more question when something is missing, polishes a version you can post, and never makes things up: nothing you did not say goes into your logbook. Edit the record whenever you like. Launch promotion: three write-ups a day, free of charge, for as long as the promotion runs. No recording leaves your iPhone. EVERY DIVE, DRAWN The watch records each dive second by second and the phone draws it: the depth curve, descent and ascent speed, water temperature, time spent at the bottom, mean depth. A session page opens on the day's picture, its highlights, its figures and its dives numbered, the way a dive computer's app opens a session. When the watch had to restart mid-session, the day still reads as one; split it if you disagree. BEYOND 6 METERS, NOTHING IS MADE UP The wrist sensor reads to about 6 meters, and a deeper dive is logged as exactly that: "6 m+". Import the log of your dive computer and its deeper reading joins the same dive: the curve past 6 meters, the real maximum, the map of where you went in, always named as that instrument's. SHARE IT, EXPORT IT, KEEP IT - A dive card to post: number, depth, time and the curve as one image - A PDF logbook with every dive's picture, CSV for a spreadsheet, UDDF for other logbook apps, a full JSON backup - An optional cloud logbook with Sign in with Apple: the same records on every iPhone, safe when you replace one A DIVE COMPUTER ON YOUR WRIST - Depth, temperature and heart rate live, color-coded from teal to orange as you go deeper - Dive counting, descent and ascent times, a surface rest timer, depth and time alarms - Freedive or mermaid sets, each with its own timing - The clocks: static, dynamic with the distance counted from your wall turns, tables, interval, stopwatch; worn as the breath-holder or as the buddy - Everything stays lit through Water Lock and wrist-down TRAIN YOUR BREATH-HOLD ON DRY LAND CO₂ tables, O₂ tables, static holds or a table of your own, with a recovery before every hold and voice cues even with the phone locked. YOUR COURSE SHEET Keep a certification course on your phone (AIDA, Molchanovs, PADI, SSI, CMAS or your own) and record results, attempts, pass dates and instructors as it goes. Link an item to the record that shows it, and when the app brings a newer version of your level, see what changed and apply only what you choose. PRIVATE BY DESIGN Your logbook stays on your devices unless you choose otherwise. Words go out only with your permission, the cloud logbook is off until you sign in, and the watch talks to no server. The app can send its own diagnostic record, never your logbook, only over Wi-Fi while charging, and you can turn it off. No tracking, no ads. Diving needs an Apple Watch with a depth sensor (Ultra, Ultra 2, Series 10 or later). Breath-hold training and the logbook run on any iPhone. Speaking about the day needs iOS 26 and a connection. Breath-hold in water only with a trained buddy watching, never alone. ShalloWeDive is a reference tool, not a replacement for certified equipment, proper training or safe diving practices. Always dive within your limits.
