Manta – Dive Log

Manta is a digital dive logbook built for amateur, professional and hobby divers that works fully offline. It replaces the paper logbook: keep every dive in your pocket, see your personal stats, and enjoy revisiting your dive story. 🌊 No internet required Divers are often on a boat, on an island, or on the shore where there's no signal. Manta works 100% offline — all your data stays safely on your device. 📒 A complete record of every dive Dive number, date, dive site, max depth, bottom time, water temperature, visibility, entry/exit time, tank (steel/aluminum) and size, start/end air pressure, weights and body weight, suit, gas (air/nitrox), current and waves, buddy, and free notes. 📊 Stats & milestones Total dives, total bottom time, your deepest and longest dive, last dive date and more. Milestones like your 100th dive are celebrated. 🗺️ Dive sites & map Save a site once and reuse it. Add coordinates and see all your sites on a map. 🎖️ Certification & equipment tracking Store multiple certifications (PADI/SSI/CMAS/NAUI). Track your gear and its service schedule. 📷 Photos Attach photos from your device to each dive so your memories live alongside your log. 🌍 Multilingual & units Turkish, English, German, Italian, French, Spanish and Arabic. Metric or imperial units (m/ft, °C/°F, bar/psi) — chosen independently of language. 🔒 Privacy first No account, no ads, no analytics. Your data stays on your device. ⚠️ Important: Manta is a dive logbook; it is NOT a dive computer or planner. It performs no decompression or safety calculations. For dive planning and safety decisions, rely on your certified dive computer and your training. Manta Pro (optional): Cloud backup, PDF export, advanced analysis, and equipment-service reminders. Available as a yearly subscription or a one-time purchase.
