Read the water
before you cast.

Capt’ns Log scores every hour against your species: pressure, tide, solunar, water temp, wind. So you know when to go, where to focus, and what to use.

The Score

One number. Every hour. Every species.

Pressure trends, wind direction, water temp, cloud cover, moon phase, tide. The Advisor reads them all against a model tuned for your target species, then gives you a single, honest score from 0 to 100. Scroll. Watch it climb.

Conditions

The signals that move fish. And only those.

No marketing dashboards. No vanity charts. Each card is a number you’d ask another angler for. A green, amber, or coral dot tells you whether it’s working for or against you right now.

How it’s different
Trout and halibut don’t bite for the same reasons. Each species runs on its own model, weighted for pre-spawn behavior, thermal layers, light penetration, and the specific patterns that matter for that fish.
The Window

Plan to the hour. Not the day.

A weather app tells you it’s a 40° day. The Advisor tells you the bite peaks at 5:48 AM, holds through 8:12 AM, then dies for the morning. Color-coded by score. Tap any hour to see exactly what changed.

Tomorrow’s window starts strong but a building cold front cuts the second day in half. Now you know to fish hard before noon.

Lure recommendations

What’s in your tackle box tonight.

The Advisor matches conditions to lures from a per-species playbook. You get three picks, ranked by confidence, with the actual reason next to each: the falling pressure, the stained water, the light angle.

Tap any pick for rigging, retrieve cadence, and when it works best.

Your Journal

Every catch makes the next one easier.

Log a fish in 30 seconds: species, size, lure, photo. Conditions are captured automatically. After ten catches the Journal starts surfacing your own patterns: which pressure trends produce, which lures are actually working for you, what time of day your big fish come from.

No social feed. No leaderboards. Just your fishing intelligence, compounding.

Falling pressure precedes 64% of your bass catches over 3 lb.

We don’t know what lakes you fish.

Capt’ns Log is local-first. Your catches live on your phone. Sync to the cloud is opt-in. No ads, no third-party trackers, no data brokers. The spot is still yours.

On-device first
Catches, photos, and patterns are computed and stored locally. Nothing leaves your phone unless you turn on sync.
No third parties
Zero analytics SDKs. Zero ad networks. Zero data sold. Conditions come from public sources; nothing flows the other way.
Spots stay secret
Saved locations and pins live on your device. Sharing a spot takes a deliberate tap.

FAQ

Questions, answered.

Yes. Tap "Prep for This Trip" before you leave service and the app caches the next 48 hours of conditions, tide tables, your saved spots, and the full lure playbook for your target species. New catches sync when you’re back on a network.
The score is a transparent weighted model, not a black box. Pressure trend, wind, water temp, cloud cover, moon phase, and tide each contribute according to a species-specific recipe. You can see exactly what changed when the score moves.
At launch: largemouth and smallmouth bass; rainbow, brown, brook, and speckled trout; California and Pacific halibut; walleye, catfish, striper, and corbina. Each runs on its own scoring engine. Trout and halibut don’t bite for the same reasons.
Yes. Catches, photos, and patterns are computed and stored on-device. Cloud sync is opt-in. We don’t sell data, run third-party analytics, or share saved locations. Sharing a spot takes a deliberate tap.
Free to download. The core advisor, catch log, and journal are free. No subscription traps, no ads.
We’re a small team and shipping the right experience on one platform is better than shipping a watered-down one on two. Android is on the roadmap once 1.0 settles.
