Fish Catch Diary: Fishing Log

Your best spots stay your secret. Fully offline, account-free. Keep catches and spots on your phone, and see the tide & weather patterns behind your bites.

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.
