What it does

A buzz before the water moves

Live generation schedules for 20 Southeastern reservoirs — TVA, U.S. Army Corps, and Alabama Power in one place — with a push alert before the dam starts pulling. When the current turns the fish on, you're already sitting on the right spot instead of hearing about it at the ramp.

  • Hour-by-hour schedules, straight from the source
  • Alerts fire even when the app is closed
  • Lake levels, flow, and spill where the agency publishes them

Lightning Watch

Arm it and a server watches the sky around your position — boat, bank, or deer stand — and buzzes your phone and your watch even with the app closed. Built by an angler who's been caught on the wrong end of the lake one time too many.

  • Runs server-side — your screen can be off
  • Escalating alerts as strikes get closer
  • Expires automatically; your position is deleted after the watch ends

Tournament Mode

Check-in countdown with reminders at 1 hour and 30 minutes, generation alerts for your lake, an emergency card, and a deterministic game plan built from public data — tournament-safe by design: no AI chat, legal in competition. Practice Mode scouts future days and arms your alerts automatically at 6 AM on trip day.

  • Tournament calendar with week-of reminders
  • Game plan from generation, weather, and solunar data
  • Practice days feed straight into your notes

A catch log that learns your lakes

Every catch is stamped with the conditions the moment you log it — current moving or slack, pressure rising or falling, feeding windows. Bite patterns build themselves: time of day, pressure, top lures, spot types. Your history becomes your edge.

  • Ten-second logging from the map screen
  • Insights: best bag, averages, career top 5, per-trip stats
  • Spot chips, custom spots, and sunlight labels

Trip reports worth sharing

One tap builds a clean PDF of your day — stats, conditions, bite patterns — ready to text a buddy or answer the eternal ramp question, "how'd y'all do?" Your spots and GPS never leave your phone unless you choose to share them.

  • Date-stamped PDF in seconds
  • No GPS coordinates in reports — ever
  • Share sheet straight to texts, email, or group chats

The whole program in one place

The stuff serious anglers keep in three notebooks and a glovebox, in one field book:

  • Rod & reel rack with technique coverage and current lineup
  • Batteries and electronics with warranty countdowns
  • Motor, serial, and dealer info for the service call
  • Licenses and insurance cards, one tap away at check-in
  • Waypoints with GPX/KMZ export — your maps stay yours
  • Automatic weekly backup to your own Google Drive
