I rarely leave detailed reviews, but this app is really well-made and seems underrated. The interface is incredibly easy and satisfying, and I love the AI analysis feature. It's free with no annoying payments, which makes it even better. I've tried dozens of apps, but this one is hands-down the best and truly helpful.

Amazing! Beautiful and functional interface.

Unlike complex subscription apps, this one is clean and minimal — does exactly what it promises. The widget is great, and the animated animals in the AI report are a delightful touch.

I've tried many apps, but this is the best. Switched from a paid premium app and this has more features — and it's free. Love it.
