Know if today's worth the drive before you load the truck.

PrimeBite gives you a 1-to-5 fish activity rating for the species you actually target — bass, walleye, muskie, pike, yellowfin, mahi, bigeye, black marlin, and blue marlin. Each species has its own math. Other species fall back to a Solunar Windows baseline so you can still log them and see their windows. Every rating shows the math behind it. Tap any number to see the weather, moon, pressure, and species-specific drivers that built it.

Three things make PrimeBite different.

1) THE RATING IS HONEST.
A 1.8 means save the drive. A 4.5 means clear your schedule. Each species has its own evidence base — bass research drives the bass rating, walleye research drives walleye. No one-size-fits-all guess.

2) THE WEATHER PAGE IS BUILT FOR ANGLERS.
Tide tables. 48-hour pressure trend. Wind-wave vs. ocean swell breakdown. Plankton activity for offshore species. The conditions that actually drive the bite — not a generic weather widget.

3) THE LOGBOOK LEARNS YOUR PATTERNS.
Every catch you save captures a 7-day weather lead-up. Over time, the app shows you your personal patterns — your best bass come on falling pressure at this lake, your best walleye hit on a 3-day warming trend. Nobody else does this.

A few things you won't find:
• No ads, no tracking, no social feed
• No "every day is prime time" — when conditions are bad, we'll say so
• No paywall on today's rating — the math is free for everyone
