What breaks without a system
Liability gaps
Missing medical forms, unsigned waivers, and unverified credentials create legal exposure for every dive.
Lost records
Student histories scattered across spreadsheets, WhatsApp, and filing cabinets. Unrecoverable when you need them most.
Compliance blind spots
No automated enforcement of agency standards, depth ratios, or prerequisites. One missed check ends programs.
Built for how instructors actually work
Compliance-first, offline-capable, and built for the realities of professional dive instruction.
Certification audit trail
Every skill signoff, every override, every document — timestamped and tamper-proof.
Student liability documentation
Medical forms, liability releases, and waivers generated, signed, and filed automatically to Google Drive.
Agency-agnostic verification
