The fish don't care how you feel.
They care about pressure, temperature, and the moon.
So should your logbook.
Bassai is for anglers who read water before they read reels. It records the quiet signal — pressure drift, tide phase, water clarity, the direction a system is moving — so that patterns can reveal themselves after fifty trips, not fifty likes.
No leaderboards. No sponsored bait ads. No push notifications telling you some stranger caught a seven-pounder. Just your own log, your own conditions, your own patterns. The fish notice everything. We decided to write it down.
A catch is a photo, a weight, maybe a lure — the part you want to remember. The part that made the fish eat — pressure drift, wind shift, moon phase, water temp, tide, the lake's name, the nearest gauge — is the other ninety percent, and it's the part you'd lose by tomorrow morning. Bassai attaches all of it automatically, the instant you drop the pin. No forms, no fields, no "I'll fill it in later."
Background GPS, catch count, and the lake name on your lock screen — the Dynamic Island runs a quiet activity so you can fish without unlocking. Pause when you shore for lunch. The app knows the difference between a second trip and a resumed one.
Temperature, pressure, wind direction, tide phase, water clarity, the nearest USGS gauge. Attached automatically to every catch — no typing, no guessing, no "best recollection" after the beer. If your phone was offline, the enrichment backfills the moment you come back in range.
Hank is the AI inside the app. He reads your structured log — weather, pressure, water, lure, gear — and answers the questions a guide on your boat would answer. What you had working in July of 2025. What pattern you'd try tomorrow given a falling barometer and mid-50s water. When you chat, Bassai sends your message, prior Hank chat context, saved Hank profile, and visible trip or catch details needed to answer. He does not receive raw GPS, photo filenames, or your private notes.
A tap on a catch renders a 9:16 card from the photo, the weight, and the conditions you fished. Catch cards have no map, no path, no GPS — the spot stays yours. The watermark reads Bassai · bassai.com · @getbassai, every time, everywhere the card goes.
Bassai is built around your own log, your own conditions, and the spots you choose to keep private. The core log stays usable for free — including opening every trip in full; Plus adds Live Trip mode and deeper tools for reading the pattern already in your trips.
Built for iPhone on iOS 18+. Free to log · Plus unlocks Chat with Hank.
