KB Quick is a professional reference and workflow tool, available to any diagnostic laboratory professional, microbiologist, or veterinarian worldwide. It supports the Kirby-Bauer disk-diffusion method of antibiotic
susceptibility testing. Accounts are free and open to anyone; no invitation, organizational affiliation, or pre-approval is required.

Go from a photo to an annotated, shareable plate report in minutes — entirely on-device.

KEY FEATURES

Smart Plate & Disk Detection

Computer vision automatically locates the plate and every antibiotic disk in the captured image. Supports optional ArUco fiducial markers for precise scaling on irregular setups.

Manual Editing

Reposition, add, or delete disks in a zoomed editor for full control over the final measurement set.

Guided Zone Measurement

Drag-to-size each inhibition zone with sub-millimeter precision. Mark zones as "No Zone" with a single tap.

Standards-Aligned Data Capture

Record precise zone measurements together with the antibiotic, organism, host-species, and clinical-indication details that susceptibility interpretation depends on — so your measurement record is complete and structured
for whatever breakpoint standard your lab uses (EUCAST, CLSI, or custom).

Shareable PDF Report

Generate a shareable A4 PDF of your annotated plate — every disk labeled with its measurement (or "No Zone" marker) and antibiotic code — alongside the case identifier. Designed to print cleanly on standard paper.

Six-Language UI

English, Russian, Tajik, Spanish, Brazilian Portuguese, and Vietnamese, with in-app switching at any time.

On-Device & Offline

Capture, detect, and measure with no internet connection required — the full capture-and-measurement workflow runs on your device. Share the resulting report by email, messaging, or print.

DISCLAIMER

KB Quick is a decision-support and workflow tool for trained laboratory professionals. All measurements and interpretations should be reviewed against institutional protocols before any clinical or treatment use. The app
does not make diagnoses or treatment recommendations and is not a substitute for professional judgement.
