For paddleboarders & kayakers

Every paddle,
remembered.

Splashtag quietly records your route, ties your photos to the places you took them, and tells you what the water is like before you leave the house. A nature journal with sensors — not another feed.

The logbook

Your route draws itself

Press start and put the phone in the dry bag. Splashtag records every stroke offline — auto-pause when you drift, honest gaps when GPS drops under a bridge — then lays your morning on a water-first map.

Pictures pinned to the water

Photos you take on a trip attach themselves to the route, right where you took them. Tap a shoreline photo years later and see every visit to that exact place.

Conditions

Know the water before you see it

Wind and gusts, air and water temperature, UV, air quality, daylight left — for the exact launch you're headed to. Safety alerts are never paywalled: offshore wind and cold-water warnings come free, always.

Scrapbooks

Mornings that become keepsakes

Pick a few trips and Splashtag lays out a scrapbook — routes, photos, weather stamps, the numbers that matter — ready to share as a link or print as a book. Effortless is the whole point.

The personal atlas

A map that becomes a memoir

Every trip you record joins one quiet map of your life on the water. Zoom out at the end of a season and see it: the home lake worn smooth with laps, the one big crossing you still talk about.

The safety promise

The safe way home is never a paid feature

Live-share your paddle with someone on shore. Set a float plan, and if you're not back by your ETA, we alert your contact with your live position. Free, forever — that is a promise, not a plan.

Float plan

Name a contact and an ETA at launch. Overdue? They get your live link automatically.

Offshore wind warnings

The wind that blows you out is the one you notice last. We flag it before you launch.

Cold-water guidance

Water under 60°F changes the rules. Immersion guidance appears when it matters.
