Everything Dyvo does with a dive
Dyvo is built on one idea: nothing a diver types in should have to be typed twice. The map, the trips, the badges, the stats and the recaps are all derived from your dives, recomputed every time the logbook changes — which is why importing twenty years of paper pays you back the instant it lands.
The logbook
The record itself: unlimited, free, and yours to take away in two formats whenever you want.
A complete dive record
Date and site-local time, site and coordinates, max and average depth, bottom time, gas mix and tank pressures, water and air temperature, visibility, current in knots, exposure suit and weight, dive type, buddy, marine life, gear used, notes and photos.
Search and filters that keep up
Search across site, location, buddy and notes; filter by dive type and year. Lifetime totals — dives logged, bottom time, deepest — stay pinned at the top.
Depth profile charts
Any dive imported from a dive computer or Apple Watch carries its depth-over-time samples, drawn as a chart on the dive’s detail screen.
Photos, corrected for depth
Water eats red first. Dyvo measures each channel’s histogram and stretches it back, with a strength slider you own — your original file is never overwritten.
A dive timer on the Lock Screen
A Live Activity that survives the app being killed, plus a home-screen widget and Siri Shortcuts for logging a dive and asking for your stats.
Sync that costs you nothing
Dives and photos live in your own iCloud private database, so storage lands on your quota and no server of ours ever sees them.
The globe and the map
Where you have been, drawn rather than listed.
A photographic globe
MapKit imagery with a pin for every site you have logged, clustered as you zoom out. Tap a pin for the dives you logged there.
300+ dive sites built in
A hand-curated catalog of well-known sites with area, region and an approximate position, searchable by name or by what is nearest to you right now.
A world map in your stats
The selected range’s sites dotted on a drawn world map that renders offline and instantly, and pushes to full-screen MapKit imagery when you tap it.
Planning the next one
The half of the app that looks forward rather than back. See how dive planning works →
Divability score
A 0–100 score and an Excellent / Good / Marginal / Poor band, synthesised from swell, period, wind, current and rain and calibrated against the question that matters: would an operator run today?
Marine warnings, always free
Small-craft advisories, gale, storm and special marine warnings, high surf, rip current and tropical alerts from the US National Weather Service. Safety information is never behind the paywall. Free
Tides, currents and slack water
NOAA harmonic and current-prediction stations where they exist — slack windows, set and strength, the day’s peak flood and ebb — with global station and modelled fallbacks, labelled honestly either way. Pro
Daylight and visibility outlook
Sunrise and sunset in site-local time, day length, and a warning when a planned start crowds sunset — plus an estimated visibility band read from a trailing five-day window of swell, chop, wind and rain. Pro
Everything derived from the dives you already logged
None of this is data entry. All of it is recomputed the moment your logbook changes.
60 badges
Count, type, depth, gas, duration, conditions, exposure, marine life, travel and habit criteria. Every badge is pinned to the exact dive that unlocked it, and an import awards everything it earned retroactively. Free
Trips, grouped automatically
Consecutive dives close in time and space over more than one day become a trip. Name it, set its dates, split it or pull a dive out — you correct the boundaries and the rule re-runs. Free
A stats dashboard
Depth and duration distributions, gas mix, seasonality, sites and regions, buddies, gear and certifications, over all time or any year or range you pick.
Year in Review and recap cards
A rendered, shareable 9:16 card per year and per trip, with photo highlights pulled from that year’s dives.
Marine life on a dive
Log what you saw, and see it counted across your logbook and on a dedicated share card style.
Share cards in three styles
Highlights, Marine Life and Conditions — each offered only when the dive actually contains what it needs.
Gear, cards and crew
Gear locker
Regulators, computers, suits, lights and more, with brand, model, serial, purchase date, a photo, and a service interval that computes “47 dives since last service.” Retire an item rather than delete it and your dive history survives.
Certification wallet
Agency, level, number, dates, instructor and scans of both sides, with an expiry state for the credentials that lapse. The card viewer works offline, because the shop counter is where you need it. Free
Buddies and shared dives
Connect by a private link — there is no user search and no handles — then share the dives you choose. Access is enforced by iCloud’s servers, not by a filter in the app.
Also on This Dive
When two buddies log the same dive, Dyvo links the records so the dive detail shows every diver’s log side by side, without either of you writing to the other’s logbook.
Built the way you would want a logbook built
Private by design
Sign in with Apple only. No ads, no third-party analytics, nothing sold or shared with advertisers. Profile → Delete Account erases everything.
Export, free forever
CSV for the complete record, UDDF 3.2 for interchange with the rest of the diving world, depth profiles included. A logbook you cannot take with you is a logbook held hostage. Free
12 languages
English, German, Spanish (Spain and Latin America), French, Indonesian, Italian, Japanese, Korean, Dutch, Brazilian Portuguese and Simplified Chinese — with the vocabulary divers actually use in each.
Everything above starts free.
