Salt water, more species, more languages. Right now: 10 freshwater species. The bot works at any lake or river in the world — set a spot, get a forecast.

Anglers deserve forecasts they can question.

Q: Which species are calibrated?

Ten freshwater species — carp, pike, perch, bream, zander, crucian carp, catfish, brown trout, rainbow trout, Atlantic salmon. Each has its own optimal temperature range, pressure sensitivity, solunar weighting, and wind tolerance.

🟢 Active feeding season — Crucian Carp

Five multipliers — solunar, pressure, wind, temperature, cloud cover — combine into one integer score from 1 to 10. Every factor is visible, so you can see exactly why the score is what it is. Competitors paywall the formula.

How we do it differently

Competitors paywall the formula. You see a score — say, 7 — but you don't know why it's 7. Was the pressure high? Is the moon in the right phase? Without the formula, a rating is faith, not data.

We build differently. Three things that follow from that:

a · TRANSPARENT SCORE

Solunar × pressure × wind × temperature × cloud

Each multiplier is a separate number in the bot's reply. You see which factor drags the score down: pressure crashing while cloud cover is 100% — you see it, not "trust the magic 7".

b · PRESSURE ALERTS

DM when pressure drops fast

Fast pressure drops are a classic pre-front feeding signal — and pike or zander respond more strongly than carp or catfish. Per-species sensitivity is calibrated in the formula. The bot DMs you when a drop starts at your spot.

c · GROUP CHATS

One chat, one forecast

The group admin sets a shared spot — any member runs /forecast and gets a shared bite card. No private duplicates, no stale screenshots forwarded around.

Why is your bite formula transparent when competitors hide theirs?

Trust. A bite score is only useful when you understand why it's what it is. If pressure is crashing but cloud cover is 100%, you want to see which factor is dragging the score down — not take a "magic 7" on faith. Anglers deserve forecasts they can question.

How scientifically rigorous is the formula?

More rigorous than every competitor — and honest about the parts where the science is still being argued.

The formula is calibrated per species. Each of the seven fish has its own temperature range, pressure sensitivity, solunar weighting, wind tolerance, and active season — based on documented fisheries observation. Pike are cold-water predators that respond to pressure shifts. Zander hunt in low light (high solunar weight). Carp avoid chop (low wind tolerance). These per-species patterns are well-grounded.

What's debated is each factor's underlying mechanism. Temperature affecting metabolism — strong science. Pressure as a direct trigger — likely a proxy for the broader weather shift, evidence is mixed. Solunar timing — anglers' wisdom that some studies support, others don't. We show all five factors as separate numbers so you can see what's driving the score for your species, your spot, your conditions — and apply your own judgment.

Do I need to install an app?

Where does the weather data come from?

Open-Meteo — free, no API key, combines ECMWF + DWD ICON models. For hydrology (river level) we use GloFAS.
