Been using phyphox for a couple months now. It’s basically an app that lets you turn your phone into all sorts of cool science gadgets. Pretty solid if you’re into that kind of thing.
Here’s what you do: there’s a bunch of pre-made experiments you can just tap and start – stuff like using your phone as a pendulum or a sonar. And it’s got some neat data analysis tools too, so you can export all the raw data and play around with it. And you can even create your own custom experiments on the phyphox website and share them with friends.
Look, if you’re into science apps or just want to mess around with your phone’s sensors, you’ll probably like this. It’s not perfect – the UI can be a bit confusing at first – but overall it does the job. Worth checking out.
