Great Measuring Tool

Was able to successfully measure deck movement between the boards and the railing, to establishing whether to create a permanent pier on my railing for my telescope.

Results can be exported out in different formats to view later.

Combine with an LLM!

Guys! ChatGPT 5.6 Sol and Claude Fable can accurately and intelligently deconstruct exported .CSV data from Phyphox. They can generate a ton of charts highlighting the most useful observations. Just make sure you use high / extended reasoning modes, but you’ll genuinely receive mindblowing, high quality analysis of your data and is the perfect way to have fun with PhyPjox. Analyze your driving using this combo! It’s soooo cool.
