ShalloWeDive

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, now paired with an iPhone companion for your dive logbook. Whether you're snorkeling, freediving, spearfishing, or just playing in the ocean, 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 — from safe (teal) through caution (yellow) to danger (orange) — so you always know where you are at a glance, without looking away from the water. On Your Watch - Real-time depth and water temperature from the built-in depth sensor - Heart rate monitoring during every dive - Freediving-standard surface rest timer between dives - Multi-dive session tracking with automatic dive counting - Descent and ascent time analysis for each dive - A dive logbook on your watch, saved between sessions - Look back at earlier dives during a multi-dive session, without ending it New: The iPhone Companion Review your whole logbook on a bigger screen and make each dive count: - Add the dive site, buddy, gear, notes, and a personal rating - Browse and revisit every past session at home - Dives sync from your watch automatically, with a manual "Sync all to phone" whenever you want Your watch and iPhone connect directly, on-device — no account, no server, and your logbook never leaves your devices. Beyond the Measurement Range The depth sensor is built for shallow water down to about 6 meters. If you choose to dive past that range, the new "No Limit" mode silences the depth alerts with a single turn of the dial, and the watch shows a calm "beyond range" readout instead of a false alarm — honest feedback, never noise. Private by Design All data stays on your devices. No account. No server. No tracking. No ads. Requires an Apple Watch with a depth sensor (Ultra, Ultra 2, Series 10, or later). The companion app is optional and runs on your iPhone; the two sync directly, with no internet connection needed. ShalloWeDive is a reference tool for shallow water activities. It does not replace certified diving equipment, proper training, or safe diving practices. Always dive within your personal limits.
