Fish Catch Diary: Fishing Log

On the rocks, the breakwater, or a mountain stream — even with no signal. Log the fish the moment you land it. And your spots stay your secret. Fish Catch Diary is a private, fully offline fishing log. No account. No social feed. Your catches and your secret spots live on your phone, and nowhere else. — What you can do — ◆ Log a catch in seconds 　Pick the species, drag the ruler to measure the size, save. Minimal taps, even mid-cast. ◆ Add the details later 　Photos, spot, GPS, weather, air & water temp, wind, pressure, tide, and high/low tide times. ◆ Your own private spot map 　Pin your trips and look back at each spot's history — species, trip count, biggest fish. ◆ Understand your fishing 　Monthly catches, top species, personal bests, best spots, and how your catches correlate with tide, weather, wind and pressure — all from your own data. ◆ Tackle box 　Keep your rods, reels and lures in one place. ◆ Built for any water 　Switch cm/inch, g/lb, °C/°F. Add any species — it works anywhere in the world. ◆ CSV export 　Take your data with you for your own analysis or backup. — Made for you if — ・You'd rather not broadcast where you caught that fish ・You fish off-grid — rocks, offshore breakwaters, headwaters ・You want to see the tide and weather behind your bites ・You're tired of social apps and subscriptions ・You just want a quiet, private fishing journal — Privacy & peace of mind — ・No account required. ・Catches, spots and photos are stored on your device and never sent to a server. ・Even the insight comments are computed on-device.
