TideMark
Get the app
The UK sea fishing app · free for iPhone and Android
Tide times, wind and swell over your mark, and a catch log that fills itself in. Then start a competition in seconds, just you and a couple of mates or the whole club, and watch the leaderboard sort itself out.
Competitions
Every catch goes in with a photo, the leaderboard adds itself up, and nobody's marks are ever shared. Two ways to play:
Biggest bass this month. First ray of the season. Most species over the bank holiday. Start one in ten seconds, send the code to the group chat, and settle the argument for good.
Set the start and finish, add a weigh-in window, and require photo proof. Approve entries yourself if you want to. The results add up as the catches come in, with no chasing photos on WhatsApp and no spreadsheet.
How a match works
Set the day, the start and finish, and a weigh-in window. Share one code with the club. Every catch lands in one photo pool, and the leaderboard adds itself up as the day goes on.
You decide the rules: photo proof required, approve every entry yourself, and count only catches from during the match.
Try it now
This is the same tide engine that runs inside the app. Pick a harbour and drag along the curve.
Tides and weather
Pick your stretch of coast and see wind, gusts, waves or swell sitting over the water, then play it forward through the week.
Every mark has its own page: the tide curve for the next few days, high and low times and heights, and a score for each day that tells you why — wind, sea state, how hard the tide is running, springs or neaps.
Named marks — forts, towers, buoys, wrecks and banks — sit on the map, with satellite view to spot gullies, reefs and sandbars.
Catch log
Log the species, size and a photo in a few taps. The tide, wind and sea at that moment are stamped on automatically. Location is stripped from every photo before it's saved, so a picture never gives your mark away. Export the whole log as a spreadsheet whenever you like.
The tour
Straight talking
Get TideMark
TideMark is in testing now with anglers around the coast. Testing costs nothing, and all we ask is that you tell us what's broken, what's missing and what annoys you.
On iPhone, install Apple's TestFlight app first, then tap the link. On Android, Google only opens the test to Gmail addresses we've added, so send us the one on your phone and we'll reply with the link.
Yes, for the 55 harbours worked out on the phone from real tide-gauge records. Wind and sea forecasts need a connection to update.
Your choice. The app shows local time by default, and can show GMT all year so it matches a printed tide table.
Both. The tide, wind, waves and swell are the same whether you're on the beach or afloat. Tidal stream rates for boats aren't in the app yet.
Anyone can start one, for a few mates or a whole club. The organiser sets the day, start and finish times and a weigh-in window, then shares a code. Everyone's catches go into one photo pool and the leaderboard totals itself. Catches count by the time the photo was taken, so anglers with no signal can send them in at the weigh-in.
No adverts and no tracking. Your catches stay on your phone unless you join a competition. Location is stripped from every photo. You can delete your account from inside the app, or from this site. The full detail is in the privacy policy.
Near a gauge, from that gauge's own record, fitted by TideMark: Environment Agency tide gauges under the Open Government Licence. Elsewhere, from the nearest ADMIRALTY UK tide station, or a global tide model further offshore. Every source is listed in the app's settings.
