## What 4divers does

4divers is a dive logging and community app for scuba divers. It solves three problems every diver faces:

1. **Dive logbook** — Log depth, time, visibility, temperature, dive site, dive center, and buddies. Every dive entry is searchable and shareable via link. Replaces paper logbooks.

2. **Digital certification card** — Store and verify certifications from any agency (PADI, SSI, TDI, SDI, CMAS, and others). Share a tamper-proof card via a single link. Accepted at dive centers worldwide.

3. **Dive site and center finder** — A worldwide database of dive sites and dive centers. Search by name or location. Includes walls, wrecks, reefs, and freshwater sites.

4. **Dive buddies** — Find and connect with other divers. Share logbook entries. Plan trips together.

## Who it's for

Any certified scuba diver regardless of agency or certification level. Works equally for recreational divers, technical divers, and dive professionals.
