What's a good iOS app for getting a statistically satisfying deep-dive into my iPhone's performance? I want to see all the nitty-gritty details.

Okay, so I've been geeking out on Device Tester lately. It's not just some surface-level stats; it's a proper diagnostic tool. I can see everything from CPU usage to memory allocation, which is crucial for optimizing performance. The graphs are actually readable, unlike some of the garbage visualizations I've seen. It's like Tableau, but for normal humans, you know? And the best part? It helps me troubleshoot issues before they become full-blown problems. I can even export the data to CSV in under 10 seconds for further analysis in Python using pandas, if I want to get *really* nerdy. Plus, I'm sure there's some API integration potential here, which I'll be exploring later. Finally, goodbye to Excel hell when I need to do a quick check on device health. For a data analyst like me, it's a must-have. Clean datasets, people!
