Other fishing apps give you the data. Castwise tells you what to do with it.
Get a clear answer on where to fish, when to go, what to target and why—by interpreting tide, weather, swell, terrain, season, catch history and safety together.
Rolled out across the UK and ready to use wherever you fish.
Castwise keeps fishing potential, safety and data confidence distinct so a single number cannot hide what matters.
Fishing
Raw fishing potential
A 0–100 species-and-mark score built from tide, range, season, light, wind, swell, pressure, sea temperature, clarity, ground and structure.
Safety
Safety-adjusted recommendation
Every detected concern is listed. Relevant risks subtract transparent points; high risk requires acknowledgement and critical risk or missing essential data is non-recommendable.
Evidence
Input confidence
Confidence describes the completeness and quality of the data behind the result. It is not a catch probability and never turns a forecast into a guarantee.
Spring tide and air temperature are shown as warnings but do not change mark points because nearby marks share those conditions. A mark-specific tide cut-off or exposed hazard can still reduce its recommendation. Sea temperature still affects species suitability. Core safety information is free.
Learning from anglers without publishing their marks.
Your private history improves your own recommendations. Community learning is deliberately coarser and can be disabled from Account.
Personal
Your own pattern
Catches and blanks help tune the baits, rigs, tides, ground and seasons that work for you. Your individual log remains yours.
Community
Thresholded evidence
Completed outcomes can enter an aggregate only when at least eight sessions from five anglers support the bucket. Individual anglers are not shown.
Marks
Exact locations excluded
Private mark IDs and private region labels never enter public mark or regional aggregates. Private marks can improve only broad condition learning.
Castwise is available across England, Scotland, Wales and Northern Ireland and is designed around target species, tide window, wind, swell, access, safety, tackle, backup options and logged results. Public and private marks use the same condition-led scoring wherever you fish.
Scoring first; AI second
The deterministic engine makes the quantitative call. AI explains approved context, but its wording remains guidance and can be wrong.
Core safety stays free
Tide cut-off warnings, emergency info, basic float plans, float-plan sharing and check-in reminders are never behind a paywall.
Private marks stay private
Exact private marks and individual logs are not published. Opt-out community learning uses thresholded condition outcomes only.
Quick answers for anglers.
What is Castwise?
A UK shore fishing app that turns conditions and mark data into a clear plan.
Is Castwise just a tide app?
No. It interprets tide alongside swell, weather, terrain, species behaviour, safety risk and logged outcomes.
How does Castwise use AI?
The deterministic engine makes the quantitative recommendation. AI explains approved context and can still be wrong.
Can Castwise guarantee catches?
No. It is guidance, not a guarantee. Fishing scores help you plan smarter sessions.
Are private marks protected?
Yes. Exact private marks and individual logs are not published; community learning excludes private mark IDs and labels.
What area does Castwise cover?
Castwise covers the UK. Nationwide forecasts, scoring and planning are available now, with public marks and private custom marks supported across the country.

Frequently asked questions.
Direct answers for anglers and search engines, with no catch guarantees or invented claims.
What is Castwise?
Other fishing apps give you the data. Castwise tells you what to do with it by combining mark features, tide, weather, swell, pressure, season, catch history and safety context into ranked species and session decisions across the UK.
Is Castwise just a tide app?
No. Tide apps show raw tide times. Castwise interprets tide, weather, swell, terrain, species behaviour, safety risk and logged outcomes to produce mark-specific and species-specific fishing recommendations.
Does the AI choose the fishing marks?
No. Quantitative recommendations come from a deterministic scoring engine. AI receives approved mark, forecast and score context to explain the result, but its guidance can still be incomplete or wrong.
What area does Castwise cover?
Castwise is available across the UK. Nationwide forecasts, scoring and planning are ready now, with public marks and private custom marks supported across the country.
Can Castwise guarantee catches?
No. Castwise helps you plan better sessions, but fishing scores are guidance, not guaranteed catches.
Are private marks protected?
Yes. Exact private marks and individual catch logs are not published. When community learning is enabled, only thresholded condition outcomes can contribute; private mark IDs and private region labels are excluded.
Does Castwise replace safety judgement?
No. Raw fishing potential and detected safety risks are shown separately. Risks can reduce the recommendation score, high risk requires acknowledgement, and critical risk is non-recommendable. Users must still verify tide, access, weather, swell and local conditions.
