Riveno

Riveno tracks the hidden cost of salt exposure across all your marine gear, so every reel, zip, bearing, and buckle gets flushed and maintained at exactly the right time. Every time you hit the water, log the session: immersion hours, depth type, water temperature, and whether grit was involved. Riveno calculates a corrosion debt for each item using its archetype sensitivity, then dials the debt back the moment you flush with fresh water. Flush within an hour and earn full credit. Leave the gear sitting salty and the credit decays. The model is transparent and always reversible: edit or delete any session and every debt figure recalculates instantly from the full event ledger. Eight built-in gear archetypes cover the most salt-vulnerable kit: spinning reels, drysuit zips, rudder cables, PFD buckles, outboard flush ports, winch pawls, dive regulators, and trailer hub bearings. Each carries its own care interval, soak sensitivity, and ordered care checklist. Tick off each step when done. When a care interval closes, record what was replaced and reset the debt to zero. Riveno is entirely offline. No account, no subscription, no cloud sync, no ads. Your gear data stays on your device. The season review screen charts weekly salt load per item so you can spot the kit taking the heaviest punishment over a half-season or a full year. The consumables ledger tracks which lubricants and anodes are protecting which parts, and flags any product whose timeline overlaps with a reported gear failure.
