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, mites, damaged brood and DWV bees in real time — before you even put the frame down. Faster, calmer, repeatable.
Five detection classes
One preview, five signals
Queen and queen cells are free. Varroa, brood and DWV are unlocked by Premium.
Free
Queen cell
Queen cells on the comb — a sign of swarming or supersedure. Catch them before the colony swarms.
Premium
Varroa
Varroa destructor mites on bees and brood. Early detection is key to effective treatment.
Damaged brood
Cells with abnormal or diseased brood — a sign of colony health problems.
DWV
Bees with Deformed Wing Virus — a common symptom of heavy Varroa infestation.

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, 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 a TFLite model. No internet connection is needed to analyze the comb, and the camera image never leaves your device.
What does the app detect?
Five classes: the queen bee, Varroa mites, damaged brood, bees with Deformed Wing Virus (DWV), and queen cells. Each class has its own bounding-box color and counter on the live preview.
Does the app collect my data?
In the free mode the app sends nothing — analysis is local and offline. 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? How does Premium differ from free?
Queen bee and queen-cell detection is free forever. Premium (5 PLN/month) unlocks the other classes — Varroa, damaged brood and DWV — plus saving photos with detections, unlimited session history and (soon) PDF report export. Submitting material for model training is always 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.
