QuantIC is the UK Quantum Technology Hub in Quantum Enhanced Imaging and we’re working on new technologies that uses quantum physics – the physics of the smallest values such as atoms and photons to make the invisible visible. We’ve created this 3D augmented reality app to demonstrate some of the imaging technologies we are working on such as cameras that can see around corners and cameras that image invisible gases. To use this app, you’ll need to download and print the A4 PDF of QR codes from our website (https://quantic.ac.uk/education/) which represent items such as a laser, detector etc. Open the app on your tablet or phone and scan the printed QR codes as directed. Have fun trying it out! For more information on our research, visit quantic.ac.uk *Please note that the app has been developed as a free educational resource and is still undergoing testing; it should run without issue on suitable devices but it is supplied as is and we cannot be held liable for any issues arising from its use.

Verdict
The clearest difference is ads: QuantIC at none against Physical Constants's shown. QuantIC also leads on update cadence (every 9 days vs every 9 months) and monetization model (free vs ad-supported). Physical Constants's advantage is review sentiment (33% vs 0%). On price, rating, ratings volume and in-app purchases there is nothing between them.
