The UK Fishing Logbook App — Your Complete Digital Fishing Journal
Every catch logged. Every session recorded. Every spot saved. fishON! is the UK fishing logbook app — your complete digital fishing journal, free on iOS and Android.
Why Every Angler Needs a Fishing Logbook
A fishing logbook is the single most powerful tool for improving your catch rate. It turns scattered memories into structured data. Over time, patterns emerge that you would never spot otherwise — that carp venue fishes best in the second week of June, that your best sessions on the river happen when pressure is falling after 48 hours of stability, that a particular bait outperforms everything else on cold mornings. Without a logbook, these insights stay invisible. fishON! makes keeping a digital fishing logbook effortless — log a catch in under a minute, and the app automatically captures the environmental conditions so you never forget what was happening when you caught.
Log Every Catch in Under a Minute
fishON! catch logger is designed for speed. Take a photo, select your species, enter weight and length, confirm your location — and you are done. The app automatically records the date, time, GPS coordinates, weather conditions, barometric pressure, moon phase and tide state at the moment of the catch. No manual data entry required for conditions. Your log builds automatically as you fish. Every catch is searchable, filterable by species, venue, date, season or bait — so finding your best session data takes seconds.
Session Logging — Record the Full Picture
Beyond individual catches, fishON! lets you log complete sessions with start and end times, target species, tactics used, weather notes and a free-text journal entry. Session logs show your total catch for each outing alongside the conditions — so you can compare sessions and understand what separates a red letter day from a blank. Over time, your session history becomes an invaluable reference. Filter by venue to see all your sessions at a particular water. Filter by species to see your history for a target fish across all venues.
Personal Bests and Progress Tracking
fishON! automatically tracks your personal best for every species you have logged. Your PB wall updates the moment you catch something bigger. Monthly and annual catch summaries show your total fish caught, species diversity, most successful venues and most productive tactics. Progress tracking turns your logbook into a motivation tool — visible improvement makes you a better angler. Share your PBs to the community feed or keep them private.
Spot Saving — Never Lose a Productive Location
fishON! lets you save private fishing spots with GPS precision — exact coordinates for a swim, a mark, a hotspot that has been good to you. Private spots are completely private — they never appear on the community map, only in your own app. Add notes to each spot: depth, species caught, best tactics, seasonal notes. When you return to a venue, open your saved spots and navigate directly to the swim that produced last time. For anglers who fish big, unfamiliar waters, this feature alone is worth the download.
Correlating Environmental Data with Capture Success
Modern angling relies on understanding the microscopic shifts in your environment that trigger fish activity. By logging specific atmospheric variables alongside your catch reports, you transform subjective hunches into actionable insights. Beyond basic temperature readings, document the precise barometric pressure trends during your session, as sudden drops or rises often dictate whether fish are feeding on the bottom or moving in the water column. Note the cloud cover percentage and the direction of the wind, as these frequently correlate with the effectiveness of specific bait presentations or lure choices on UK waters. When you record water visibility and surface temperature in your digital journal, you create a long-term reference library. Over time, this data allows you to identify patterns specific to your local venues, such as how a south-westerly wind coupled with a rising pressure system consistently improves your chances for certain species. Using this historical data to plan your next session ensures you are on the bank during the most productive windows, rather than relying on guesswork or anecdotal advice that may not apply to your local lake or river conditions.
Applying Solunar Theory to Refine Your Session Timing
The application of solunar theory offers a scientific framework for predicting peak activity periods based on lunar cycles and sun positions. By documenting your success against major and minor periods, you can evaluate how these cosmic factors influence predator and carp behaviour in your specific region. Record the timing of moonrise and moonset in your logs to cross-reference these events with your bite reports. Many UK anglers find that these solunar windows act as 'switch-on' moments for shy-feeding fish. Tracking these intervals within your journal helps you understand if your current strategy aligns with the natural feeding rhythms of the fish. If your recorded catches consistently align with lunar zenith or nadir points, you can use this information to decide when to stay mobile and when to focus on precise, high-accuracy casting. Integrating this planning into every trip removes the uncertainty of sitting over empty swims for hours, allowing you to focus your effort during the periods when biology dictates fish are most likely to actively feed, significantly increasing your efficiency and success rate on the water.
