UmiLog dive site map with bottom sheet and site markers

UmiLog

Explore, plan, dive, relive — on an area-first map

An image-first iOS dive log (海ログ). You browse regions, then areas, then sites on a vector MapLibre map that works offline. Log a dive in four steps, record what you saw, and scroll the timeline afterwards. GRDB holds everything on device. Current work is the third data-excellence round: auditing site packets, grading species evidence, and clearing the journey test burndown.

Highlights

  • ▸4,597 dive sites ship in the seed database and load without a network
  • ▸Vector basemap with a runtime theme override, so the map matches the app
  • ▸Four-step logging wizard that saves species sightings in one transaction
  • ▸Site data is built from Wikidata plus a curated crosswalk, then quality-audited
