Keep your dive kit expedition-ready. ServiceDeco tracks service intervals for every piece of gear — regulators, tanks, BCDs, computers, O₂ cells, and more — and alerts you before anything goes overdue. The only app that triggers service by date, by dive count, or whichever comes first. YOUR DATA. YOUR DEVICE. No account. No cloud. Your log lives on your iPhone and exports to CSV anytime, forever. No subscription required for export. TRACK ANY GEAR • Regulators — annual service reminders by date or dive count • Tanks — VIP and hydro compliance with jurisdiction presets (US, EU, UK, AU) • Computers, BCDs, O₂ cells, rebreathers, lights, and any custom gear • Full history: date, dive count at service, cost, shop, notes WHICHEVER COMES FIRST Set an interval in days and dives. ServiceDeco monitors both and alerts you the moment either is reached — the exact trigger tech divers need and no other app fully delivers. SYSTEM STATUS AT A GLANCE The readiness dashboard shows overall fleet status. Overdue items surface first. One look tells you whether you're cleared to dive. LOG YOUR DIVES Quick dive entry tags the gear you used. Each tagged item's dive count advances automatically. No manual counting. BUILT FOR SERIOUS DIVERS Salt water and freshwater modes. Works offline on the boat or at depth. Designed to be used with wet hands. Terms of service: https://servicedeco.vercel.app/terms.html Privacy Policy: https://servicedeco.vercel.app/privacy
