A hive inspection is a race against time
- Finding the queen on a crowded comb can take ages — and every long inspection stresses the colony.
- Varroa mites and the first signs of DWV are barely visible to the naked eye until it is too late.
- Judging brood condition relies on experience and memory — hard to repeat and to document.
QueenRadar looks for you
Point your phone at the comb. A model trained on bee imagery highlights the queen and queen cells in real time — before you even put the frame down. Faster, calmer, repeatable.
Detection classes
What QueenRadar detects
For now the app detects the queen and queen cells. Detection of Varroa, brood and DWV is in preparation.

Help improve QueenRadar
Your combs train the model
The more varied comb photos and videos the model sees, the more accurately it detects the queen and queen cells — and the sooner more classes arrive: Varroa, damaged brood and DWV. If you want to help, submit your own material — it is entirely voluntary and needs no account.
- We use them solely to train the QueenRadar model.
- We store them in a secured directory and never share them with third parties.
- You can withdraw consent at any time — see the privacy policy for details.
FAQ
Frequently asked questions
Does QueenRadar work offline, without internet?
Yes. Detection runs entirely on your phone (on-device) using our AI model. No internet connection is needed to analyze the comb, and the camera image never leaves your device.
What does the app detect?
Currently the app detects the queen bee and queen cells — each with its own bounding-box color and counter on the live preview. Detection of Varroa mites, damaged brood and DWV is in preparation.
Does the app collect my data?
Comb analysis is local and offline — the camera image never leaves the phone. The app may send an anonymous crash report (no photos) only with your consent. Data (photos/videos) reaches us only when you deliberately submit it through the “Help improve QueenRadar” form, after giving consent.
Which phones does QueenRadar support?
Devices running Android 8.0 (API 26) or newer. Detection smoothness depends on your phone’s power — newer models reach a higher frame rate.
What happens to the material I submit for model training?
We use submitted photos and videos solely to train and improve the QueenRadar detection model. We store them in a secured directory, never share them with third parties, and you can withdraw consent anytime on the withdraw consent page — enter your submission ID and we delete the files from our server.
How much does the app cost?
The app is free on Google Play — no ads, no account and no subscription. Queen bee and queen-cell detection, saving photos with detections and session history are all free.
Do I need an account to use the app?
No. The app works without creating an account. Submitting material for model training also requires no registration.
