SeaLogMigration guide
From Subsurface to your phone
Subsurface is the best desktop dive log there is, and it is still a desktop dive log. Divers keep it for what it is superb at, reading almost any computer over almost any cable, and want the result in their pocket with photos, a map and a species list attached.
Move your dives, step by step
Open Subsurface and select the dives you want, or all of them.
Use File and Export, and choose UDDF.
Move the exported file to your phone: AirDrop, iCloud Drive or email all work, anything that puts it in the iOS Files app.
In SeaLog, tap the plus button, then Import dives, then the matching format.
Pick the file. Every dive arrives with its depth profile, and anything already in your logbook is skipped rather than duplicated.
What survives the move
✅ Comes across
- Every dive with its full profile
- Cylinders, gas mixes and weights
- Site names and coordinates
- Buddies and notes
⚠️ Does not
- Subsurface's planner scenarios, which are not dives
Whatever comes in can go back out: SeaLog exports the whole logbook to UDDF, CSV or PDF at any time. We would rather you could leave than have to trust us.
Questions
Should I stop using Subsurface?
No. Keep it for the cable-only computers it reads better than anything else. Use SeaLog for the part Subsurface was never trying to do: a logbook you actually enjoy opening, on the phone that is already in your pocket.
