Built for UK shore anglers

Turn UK shore-fishing data into a clear decision

Other fishing apps give you the data. Castwise tells you what to do with it: where to fish, when to go, what to target and why. Castwise is rolled out across the UK and ready to use for shore-fishing planning wherever you fish.

UK sea fishing, made clear

What is Castwise?

Other fishing apps give you the data. Castwise tells you what to do with it. Castwise is rolled out across the UK and ready to use for shore-fishing planning wherever you fish. It combines tide, weather, swell, pressure, moon phase, ground type, depth, season, catch history and safety data to recommend where to fish, when to go, what species to target and what tackle to use.

Is Castwise just a tide app?

No. Tide apps show raw tide times. Castwise interprets tide, weather, swell, terrain, species behaviour, safety risk and your logged outcomes to produce mark-specific and species-specific fishing recommendations.

Who is Castwise for?

Castwise is built for UK shore anglers — beach, rock, pier, estuary and harbour fishers — from casual anglers to regular locals and specimen hunters who want sharper planning without exposing private marks.

What area does Castwise cover?

Castwise is rolled out across the UK and ready to use for shore-fishing planning wherever you fish. UK-wide forecasts, scoring and planning are available now, with public marks and private custom marks supported across the country.

One app for all four UK nations

Castwise is not confined to a launch county or a handful of south-west marks. The same planning model supports public and private shore marks around the whole UK coast.

England

Plan beaches, estuaries, piers, harbours and rock marks from the North Sea to the Channel and Atlantic coasts.

Scotland

Compare exposed mainland and island coasts, sheltered sea lochs and local private marks using the same condition-led method.

Wales

Score surf beaches, estuaries, rough ground and strong tidal coasts while keeping local access and safety checks visible.

Northern Ireland

Use UK-wide forecasts and scoring for public or private shore marks, then verify the current DAERA rules for retained fish.

Other fishing apps give you the data. Castwise tells you what to do with it.

Tide tables, forecasts and maps are useful inputs. Castwise joins those signals into one ranked decision for your target species, marks and available session window.

How the scoring works

Castwise reads each mark and current conditions, scores every target species separately, assesses safety independently, then applies any safety penalty before ranking the best session window.

1

Read the mark

Ground, depth, structure, exposure, casting range, difficulty and known species for public and private shore marks.

2

Read the conditions

Tide stage, spring/neap range, wind, swell, pressure, sea temperature, clarity, moon and solunar periods.

3

Score each species

Every target is scored on its own, so the honest answer can be “fish bass here” or “switch target tonight”.

4

Apply the safety context

The raw fishing-potential score stays visible. Detected safety concerns then reduce the ranked recommendation score by transparent point penalties.

5

Explain the factors

Open the score to see what helped, what hurt and whether the data behind the recommendation is strong enough to trust.

6

Learn from results

Catches and blanks tune your private recommendations. Opted-in outcomes also improve thresholded community patterns without publishing private marks.

Frequently asked questions

Is Castwise a free sea fishing app?
The free tier includes core conditions, up to three ranked picks, six map marks, the full private logbook, custom marks, core safety tools, three coach questions per week and three Fish ID checks per day. Plus adds all ranked picks, the session planner, 10-day windows, alerts, higher fair-use AI limits, analytics, Species Hunt, advanced discovery, crews and the tackle locker. Guide prices are £3.59 monthly or £29.99 yearly; the store shows the binding local price and terms before purchase.
Does Castwise work offline?
Castwise can show its last cached data and run scoring on-device when signal drops. That does not create a fresh forecast: cached conditions may be stale, maps or online tools may be unavailable, and tide, weather, swell and official warnings must be rechecked before relying on a plan.
Is there an Android and iOS version?
Yes. Castwise is rolled out across the UK and ready to use on supported Android and iOS devices, with the same UK-wide scoring, planning, logbook, safety and species tools available wherever you fish.
Why should I trust the recommendations?
The quantitative recommendation comes from a deterministic scoring engine and can be opened to show its factor breakdown. AI receives approved mark and forecast context to explain or coach around that result, but AI and forecasts can still be incomplete or wrong and must not replace local judgement.
