Broover is a distilling workflow app that runs alongside the RAPT app and cloud. Your Pill registers with RAPT first as usual; Broover then reads telemetry via the RAPT Cloud API and uses it to drive a full distilling workflow — washes, runs, lots, bottled spirits, all with proper distilling math layered on top of what the Pill measures.
Register your Pill in the RAPT mobile app and confirm it's reporting gravity and temperature in the RAPT app as normal. Then in Broover's Setup → Pills tab, paste the RAPT Cloud account credentials (one-time per Broover account). Add each Pill by its Device ID (copy it from portal.rapt.io → Devices → View). Broover's poller pulls fresh readings from the RAPT Cloud API every 10 minutes, writing them into the wash that's currently linked to the Pill's fermenter.
Important: Broover doesn't pair with the Pill directly — there's no Bluetooth, no firmware flash, nothing weird. Your Pill keeps doing exactly what it does today; Broover just reads the same cloud data the RAPT app reads.
Hydrometers drift. RAPT Pills are tighter than most but they're still electromechanical sensors floating in a wash for days. Broover stores a per-Pill calibration offset (sgOffset and tempOffsetC) — type your actual hydrometer reading next to the Pill's current reading and Broover applies the difference to every future reading. The chart and ETA math use the calibrated values automatically.
Recalibrate any time. A 0.001 SG drift on a wash that's near target FG is the difference between "ready to strip" and "still has 2 days left" — calibration matters.
If you run two washes on twin fermenters with a Pill in each, Broover compares their behaviour. When one Pill registers as "stuck" but its sibling on the matching wash is fermenting at 3× the rate or faster, the more likely explanation is that the stuck Pill has a problem — wedged in foam, hibernating after a sediment coating, or hung up at a vessel wall — not that the wash itself is stuck. Broover reclassifies the verdict from "stuck" to "pill disagreement" so you check the Pill before reaching for the rouse paddle.
The RAPT app is great for the fermentation chart and Pill diagnostics — keep using it for what it does well. Broover is the workflow that wraps around the ferment: pitch a wash from a recipe, log strip runs and spirit runs against the wash, track every bottled lot back through the chain that made it, get "is my wash done" guidance based on the actual SG trajectory, dilute-to-bottle with contraction-aware math, design and print bottle labels at the end.
Over time we aim to support more of RAPT's clever gear — temperature controllers, fermentation chambers — wherever it makes sense for distillers running RAPT kit end-to-end. The goal isn't to replace the RAPT app; it's to be useful where the RAPT app isn't trying to go.
