Made around the job

Supervisor Log Book
Keep records of supervision and running panel-hour totals in a log book separate from your diver records.
Certifications Manager
Store credentials, cards, issue and expiration dates, with optional reminders so renewals never sneak up on you.
ID-verified supervisor stamps
A stamp system built for cleaner sign-off records, with identity-verified supervisor stamps.
PDF packages
Build filtered packages of dive logs, certifications, and documents for certifying bodies, employers, clients, or your own files.
Backup, export, milestones
Backup, restore, archive, and readable export tools keep your history yours. Track career milestones along the way.

Privacy posture
Local-first professional records.
Your dive history, certs, and scanned documents are work records. Most of the app works without an internet connection, and core records stay on your device unless you choose to export, back up, print, or share them.
Important: HagaLog is a personal professional record-keeping tool. It does not replace employer-required dive sheets, official regulatory submissions, medical or legal advice, or certified legal record systems.
