Know the water before you drive out.

We read the public records for every lake and river in the US — surveys, ramps, water tests, stocking — and turn them into one page you can act on.

Every published water gets the same page: surveyed depths, species with bite calendars, water tests, stocking, ramps with lanes and hours, camps on the bank — and the score for the day you are going.

Where are you fishing from?

So we can sort lakes by how far you have to drive, and use the right bite calendar for your latitude.

Screen 1 of 11

Welcome

The first screen answers one question with a picture: what does this app actually know about a lake. The top of it is our own depth chart of Okeechobee — the shoreline, the survey readings coloured by depth, the ramps. Under it, four numbers from that lake's page, three cards that show the app working, and one thing asked in return: where you are fishing from.

The map: The picture at the top is not a photograph of a lake — it is our own depth chart of Okeechobee: the shoreline we hold, the survey readings coloured by depth, the green pins of boat ramps. The scale under it is the same one used across the site, labelled from nought to the deepest reading we have.
The four numbers: Surface in acres, deepest reading, how many ramps and how many species are on record. They come from the lake's own page, so what a person sees here is exactly what they will find when they open it.
Three cards to swipe: Instead of promising what the app does, the screen shows it working: today's bite score with the window to go, the fish feeding right now with the tactic for each, and the water chemistry with every reading placed on its own scale. Swipe once and the promise is proven.
Asking for the location: The reason comes before the request: we sort lakes by how far you have to drive, and the feeding calendar shifts with latitude. Typing a town works just as well, skipping works too, and the line about the coordinates never leaving the phone sits in plain sight, not in the small print.
