How to Download Your Garmin Dive History into the Freediver App

Step 1: Install the extension

Open Fit Sync in the Chrome Web Store and add it to your browser. Pin the icon to your toolbar — you will use it every time you sync.

On a computer only. Extensions run in desktop Chrome — Chrome on a phone or tablet does not support them, so Fit Sync cannot be installed there. Once your history is across, later sessions go straight from your phone.

Step 2: Connect it to your account

Click the extension icon and pick the Freediver app as the destination. It shows a link that takes you straight to the approval page in the Freediver app — confirm there while signed in. There is nothing to copy across and no code to type.

Once approved, the extension flips to the connected state on its own, so you can close its window while that happens. The approval link is good for about a quarter of an hour; if it lapses, ask for a new one.

Step 3: Choose how far back to look

You get ready-made spans — a week, a month, a year or 10 years — or an exact date range of your own. From the second sync onwards there is also an option to fetch only new dives, starting where you left off. So after every trip you come back to the same extension and pick up what has arrived since, in one press.

If you have several seasons behind you, working in shorter windows — season by season — is easier than one jump through the whole history. Shorter windows search faster and are simpler to check.

Step 4: Review what it found

The extension lists the sessions from the window you picked. Untick the ones you do not want to bring across, and set the discipline on the rest.

Every session arrives tagged as CWT, because a FIT file does not record the discipline — your watch simply does not know it. Change it right there in the list (including all sessions at once, if the whole day was one discipline), or fix it later on the workout itself.

Step 5: Upload your dives

Press upload and that is it. You can close the extension window — the sync keeps running in the background. Dives uploaded earlier are recognised and skipped, so repeating the same window duplicates nothing.

Step 6: Check your calendar

Dives land on the dates they were actually dived, carrying their profile, max depth and time. Days where you had no workout planned get one created for you, named the way the app would name it — for example "42m CWT · 12 dives".

If a day already has a workout you planned, the extension does not guess — it asks which workout the dive belongs to. That is one of the few things you cannot undo later, so the call stays yours.
