Keep your gear in safe condition, always. "When did I last overhaul this regulator?" Your life-support gear deserves better — let DiveKeep handle your care timing. ■ Dual tracking: dives x time Overhaul "in N dives," BCD service and battery changes "in N days." Log a dive and it updates your total dives, so count-based care is spot on. ■ Never forget the post-dive rinse Gear used in the sea needs a freshwater rinse. Mark gear as "used in saltwater" and get reminded to rinse after every dive — protecting it from salt jams and corrosion. ■ Track your tank inspections Get reminders for safety-related checks like visual inspection (VIP, yearly) and hydro testing (every 5 years). ■ Preset care items Post-dive rinse, regulator overhaul, O-ring check, BCD service, computer battery change, hose check, tank visual inspection, tank hydro test, wetsuit care, fin & mask care, full rinse — in real diver language, with recommended intervals you can fully customize. ■ A collection with a care log Register regulators and BCDs with photos. Every care builds your history, and you can record costs too. ■ Three-stage reminders A heads-up as it approaches, on the day, and gently every day after until it's done. Faulty gear leads to accidents. Never miss it. ■ Tips for divers Fit the dust cap before rinsing, O-rings are consumables, follow regulations for tank inspections — 24 tips and a buddy turtle make care more fun. ■ Widget support See which gear needs care next and what's left (in dives or days) at a glance on your Home Screen.
