PLAN BETTER CALIFORNIA DIVES Explore 53 dive sites from San Diego and the Channel Islands to Monterey, the Bay Area, Mendocino, Humboldt, and Del Norte. Compare: • Estimated underwater visibility • Swell height and period • Wind speed and direction • Water temperature • Tides, currents, and rainfall • Dive and fish activity scores • Multi-day forecasts and recommended dive windows • Forecast confidence and data health
Browse sites by coastal region, explore them on the map, save your favorites, and pull to refresh for the latest available conditions.

BUILD YOUR DIVE LOGBOOK Record depth, duration, visibility, water temperature, number of descents, catches, sightings, and personal notes. Connect Apple Health to import supported dive information from an Apple Watch or compatible dive computer. Review each detected dive, choose the correct location, and add catches, sightings, visibility, and notes before saving it to your logbook.

TRACK YOUR PROGRESS See your total dives, time in the water, average visibility, deepest dive, longest session, clearest conditions, biggest catches, and personal dive history. Compare the forecast with the conditions you experienced and build a better understanding of your favorite sites over time.

TRAIN YOUR BREATH HOLD Build a safer, more consistent foundation with guided dry static-apnea sessions and apnea walks. • Adjust breath-hold time, recovery time, progression, and rounds • Choose from built-in training presets • Follow clear safety checks before every session • Record how each session felt • Track completed sessions on your device • Learn through a practical safety handbook and frequently asked questions
SpearIQ’s training tools focus on relaxation, awareness, and conservative progression—not maximum attempts.

CHECK CALIFORNIA FISH REGULATIONS Browse fishery information organized across California’s five CDFW management areas. Review species guidance, seasons, limits, closures, advisories, and Marine Protected Area resources before heading out. Regulations can change. Always confirm the current rules through official California Department of Fish and Wildlife resources.

VIEW COASTAL CAMERAS Open available coastal and underwater camera feeds for another look at current conditions before committing to a dive.

FIND YOUR CALIFORNIA DIVE CREW Connect with divers across California to: • Share condition reports • Find dive partners • Plan upcoming trips and meetups • Ask questions • Discuss equipment and techniques • Reply to community posts • Message other divers directly
SpearIQ is built for California divers who want better information, better records, smarter training, and stronger connections throughout the local spearfishing and freediving community.

IMPORTANT SAFETY INFORMATION Conditions can change quickly. Forecasts are planning tools—not guarantees of safe diving conditions. Always evaluate the site in person, verify official regulations, use appropriate equipment, dive within your training, and never dive alone. All guided breath-hold sessions are intended for dry training only. Never practice breath holding alone in water and never hyperventilate. Apnea walks require a capable, dedicated buddy and a safe, clear route. SpearIQ is not medical advice or a substitute for certified freediving instruction.

Apple Health features require permission and compatible hardware. Available dive information depends on the recording device and data stored in Apple Health.
