Tide Mark is a private saltwater fishing logbook. Keep an honest record of what you caught, where, and on what tide, without turning your journal into a public feed.

Skip the fish stories. Your spots are for you.

LOG THE CATCH
Snap a photo of the fish, pick Inshore, Offshore, or Shark (or type your own species), and save. With the location permission you allow, Tide Mark pins the catch on the map so you can find that stretch of water again. Each catch keeps the conditions from that moment: tide, wind, moon, sky, temperature, and pressure.

PLAN AROUND THE TIDES
Plan matches the tides to your past catches. Pick a day and Plan shows the tide that lined up with each logged catch, at the same height and the same direction, incoming or outgoing. It sits next to your plan notes and the full tide chart for that day, so you can see where the fish were the last time the water looked like this.

YOUR SPOTS, YOUR MAP
Mark the areas that matter and build a personal map of productive water. There are no leaderboards and no public profiles.

CALENDAR HISTORY
Look back by month or as a list of catch cards, with photos and tide heights on each day you fished. Keep bait and spot notes alongside the catch.

SHARE ON YOUR TERMS
Link a friend with an invite code when you want to. Nothing is shared until you tap Share on a trip, and you can unshare or unlink at any time.

BUILT ON THE SOUTH TEXAS COAST
Tide Mark was built in Aransas Pass for the bays around Corpus Christi and Rockport, and it works anywhere along the coast. It is made for redfish, speckled trout, flounder, snook, and whatever else you chase inshore or offshore.

Tide Mark also includes an optional Duck category, so coastal waterfowl days can live in the same private journal.
