Real app surfaces
Inside the app
Four core tabs plus widgets cover the main workflow.
Workflow map
A workflow map instead of another screenshot wall
The app already has stronger screenshot treatment lower on the page. Here, the useful thing is to show how responsibility is split across the four real tabs and where widgets fit around them.

Home to Brewing to Logs, with Settings holding the system layer
This keeps the landing page honest to the real app architecture instead of inventing a second visual product that does not exist.

Why it stays useful
Built for the full coffee loop
BrewTinker stays useful after the first setup: capture the brew, compare the result, and carry the learning forward.
Real product scope
This section now uses moving proof cards so the page keeps presenting concrete evidence of product scope instead of repeating the same headline.
Home
Today card resurfaces the next brew
The app keeps today stats, beans, and unfinished work visible instead of hiding them behind a menu.
Brewing
Quick brew and guided brew coexist
You can move between direct execution and stage-by-stage guidance without changing products.
Experiments
A/B work is part of the core flow
Experiments are resumable and belong next to everyday brewing, not in a hidden lab feature.
Logs
Heatmap and search keep history alive
A record only matters if you can retrieve, compare, and export it later.
Devices
BLE support is explicit
Acaia, Timemore, and Inkbird support are part of the product scope, not implied marketing copy.
Sync
Cloud remains optional
The product still works locally, while sign-in and sync stay available when needed.

FAQ
Common Questions

Decision point
Available where the product actually lives
This site is only the landing layer. The product itself is the iPhone app, so the final area now focuses on getting you there.
Decision point
Privacy stays part of the decision
You can read the privacy policy immediately, and cloud sync remains optional rather than required.
Decision point
Try one real brew first
Download, run a real session, and decide from actual workflow fit instead of more marketing copy.
