The basics
The app is free — catch log, maps, conditions, alerts, tournament mode, the works. A Pro tier ($24.99/year) is planned for power features down the road, and the everyday tools stay free. No ads either way.
No. There is no sign-up, no login, no password. Open it and fish. Your data is keyed to your device, not to an identity.
On your phone. Catches, waypoints, notes, and gear records are stored on the device itself — we don't run a server that holds your fishing log. The optional weekly backup goes to your own Google Drive, which we can't browse. Full details in the privacy policy.
No. GPS coordinates never leave your phone unless you export or share them on purpose. Trip report PDFs deliberately contain no coordinates at all — brag about the bag, keep the ledge.
On the water
The core of it, yes — the app loads without signal, and your log, notes, and gear book are always available. Live data (schedules, weather, radar, lightning) needs a connection, same as any weather app. Alerts you armed while you had signal still fire server-side and reach you the moment your phone reconnects.
Designed to be. The game plan is deterministic — built from public generation schedules, weather, and solunar data with no AI chat and no real-time coaching. That keeps it inside typical tournament electronics rules, but always check your trail's specific language; some circuits write their own.
No — that's the point of doing it server-side. Your phone isn't polling radar; a server does the watching and only wakes your phone to deliver an alert. Armed all day costs you almost nothing.
Twenty at launch across the TVA, U.S. Army Corps, and Alabama Power systems: Guntersville, Wheeler, Wilson, Pickwick, Kentucky, Chickamauga, Nickajack, Watts Bar, Weiss, Neely Henry, Logan Martin, Lay, Mitchell, Jordan, Martin, Yates, Thurlow, Harding, Eufaula, and Seminole. Missing yours? There's a request button on the Setup tab — lakes get added by demand.
Completely. Nothing in the app assumes a boat — Lightning Watch, the log, conditions, and alerts all key off your position, wherever that is.
Phones & installing
Google Play and App Store releases are in review now. Meanwhile the full app runs free at bassfieldbook.com — add it to your home screen and it installs like any app, alerts included. See the install guide.
If you use the browser version, add it to your Home Screen from Safari (iOS 16.4 or later) and allow notifications when asked — required for push on iPhone. The App Store version handles this automatically.
Turn on the Google Drive backup before you switch (Setup → Data). On the new phone, connect the same Drive and restore. GPX/KMZ exports are a manual belt-and-suspenders option.
Housekeeping
Setup → Data → Danger Zone erases every catch on the device. Server-side, alert records expire and delete themselves automatically within 48 hours of a watch ending — there's nothing to ask us to remove, because we don't keep it.
