The digital fishing journal
4Fish records what happens on the water — catch, location, weather, bait, rig. Precisely documented, clearly analyzed. All on your device.
Species, length, weight, bait, rig, hook size, depth, position — 4Fish captures the whole moment. The app fills in the water name and weather data automatically, while you're still standing at the water.
And if the catch was weeks ago: 4Fish reads the time and GPS position from your photo and fetches the matching historical weather. A picture in your gallery becomes a complete entry.
Sessions bring whole fishing days together — rod setup, rating and everything that goes with them. Even the day when nothing happened belongs in the journal. Especially that one.
Found a perfect spot from the boat — and next time it was somewhere out there? 4Fish saves your spots with their GPS position right on the map, along with depth, bottom structure, wraps, photos and notes.
Live navigation guides you back: your position on the map, a compass arrow, the distance in meters. Until you're standing exactly where the fish were biting.
Temperature, wind, air pressure with its trend, cloud cover, moon phase — captured automatically with every entry, at the moment of the catch. Even retroactively, via the capture date of your photos.
Because whether a day was good is rarely down to chance. Usually it's the conditions — and those are exactly what you forget first.
Captured automatically — weather block of a catch
Not a single one of these fields is yours to fill in.
In which wind did you catch at your home water? At what temperature, what pressure, what moon phase? 4Fish analyzes your entries per water — soberly, based on your own data, no guesswork.
And it compares: the current conditions are highlighted right in your statistics. You see at a glance whether today looks like the good days you remember.
4Fish works without an account, without forced cloud sync, without internet. All entries, photos and voice notes stay locally on your device — and can be backed up as a file and moved to a new device at any time.
For maps, weather and place lookup, the app only makes the technically necessary requests. Your catches, your spots, your waters: they never leave your device.
4Fish is available for Android and iOS.
