Garmin dives to MySSI logbook
Only for iPhone
$4.99
iPhone
Share a Garmin dive .fit file and it's in your MySSI logbook in seconds - dive site, depth, gas, and even your dive buddies filled in automatically!
Stop re-typing your dive data into MySSI by hand.
FitDive reads a Garmin dive computer's own .fit file and logs it straight into your MySSI e-logbook - the dive site, date, time, max depth, water temperature, and gas mix, all filled in automatically. Share a dive from the Garmin Dive app, or pick a .fit file from your phone, and it's logged in seconds.
WHAT IT DOES
- Decodes your Garmin dive computer's own file format directly - no manual entry, no copying numbers off a screen.
- Works out the dive site from the file's own GPS, falling back to your phone's location if the file has none.
- Checks your existing MySSI logbook before submitting: warns you if a dive number already exists so you never accidentally double-log a dive, and tells a genuinely open number apart from a real duplicate - showing exactly which dives it falls between either way.
- Shows you the full dive summary before it submits anything, and you can edit any field first.
BEYOND THE BASICS
- An optional Add Details screen fills in the rest of your MySSI log: dive discipline, entry type, water body and conditions, gear and gas - all quick pickers, none of it required, and Nitrox is detected automatically once O2% crosses 23%.
- Sync your MySSI dive buddies once, with their photos, then pick who was on the dive from a searchable list. Set a favorite buddy and it's pre-selected automatically on every import.
TRACK YOUR DIVES, NOT JUST IMPORT THEM
- A depth/temperature profile graph on every import, plotted straight from your dive computer's own second-by-second data - not just the max/average numbers.
- "My SSI Logbook" - a real, read-only view of your actual MySSI logbook right inside FitDive: dive #, date, site, depth, duration, matched automatically against your own Garmin data. No browser needed.
- Import your whole Garmin history in one pass: request a full data export from Garmin Connect and FitDive checks every dive in it against your MySSI logbook, showing exactly what's already logged and what's still missing - even years of dives you never touched with FitDive.
- FitDive remembers which dives it's already sent (or you chose to skip), and asks before re-importing one by accident - including a check for a dive logged from a different timezone than where you actually dove.
- Made a mistake on a dive? Delete it right from FitDive and re-import it correctly - no need to fix it by hand in MySSI. Verified dives and Education dives can't be deleted, so your certified history stays safe.
- Add a private dive site with a map - your favorite local spot doesn't need a public listing. Drop a pin (starting from your dive computer's own GPS, or your current location), name it, and it's saved to your MySSI account, reusable on every future dive there.
- Your local import history, including saved depth profiles, backs up to iCloud automatically, so a new device or reinstall doesn't start from zero.
REQUIREMENTS
- Your own MySSI account (my.divessi.com) - FitDive uses your login the same way a browser would, exactly as if you'd typed the dive in yourself.
- An internet connection - FitDive signs in, looks up dive sites, and checks your logbook live every time you import.
- A Garmin dive computer that exports .fit files (most recent Descent models).
FitDive isn't made or endorsed by SSI or Garmin - it's an independent tool built by a diver who was tired of typing the same numbers twice.
No subscription. No ads. No in-app purchases. Pay once, keep every future update.
COMING SOON
- PADI logbook support is in development - a second logbook option alongside MySSI, not a replacement.
- Android is in development.
- Apple Watch / Oceanic+ dive import is in development.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Depth profile graph — every import comes with a depth (and temperature) graph plotted from your dive computer's own second-by-second data, not just the max/average numbers.
- My SSI Logbook — a real, read-only view of your actual MySSI logbook right inside FitDive: dive #, date, site, depth, duration. No browser needed.
- Import your whole Garmin history — request a full data export from Garmin Connect and FitDive finds every dive in it, checks each one against your MySSI logbook, and shows exactly what's already logged and what's still missing — even years of dives you never touched with FitDive.
- Won't double-log a dive — FitDive remembers which dives it's already sent (or you chose to skip), and asks before re-importing one by accident.
- Delete a wrong entry, right from FitDive — made a mistake on a dive you logged? Delete it and re-import it correctly — no need to fix it by hand in MySSI. Verified dives and Education dives can't be deleted, whether or not they've been verified yet.
- Add a private dive site, with a map — your favorite local spot doesn't have to be a public listing. The pin starts at your Garmin dive's entry point, but you can switch to its exit point or your current GPS if that's a better fix, then drag to the exact spot. Name it and it's saved to your MySSI account — reusable on every future dive there, with a running count of how many dives you've logged at each one.
- Backed up to iCloud — your local import history, including saved depth profiles, mirrors to iCloud Documents automatically, so a new device or reinstall doesn't start from zero.
