### 4/5 — Great App

*2026-05-01*

The App is amazing and I’d wish Apple made something like this because when better integrated in the OS it would be perfect. Great work!

### 3/5 — A very good concept

*2026-01-09*

I really like the idea behind this application BUT it gives false information ALOT idk what background instructions u may be giving Apple Intelligence but even Siri gives more accurate results when testing than this hope too see improvements !!!

### 4/5 — Not very understanding

*2025-11-13*

I can’t talk to it for it to remember context of what I’m talking to it about. Also, I can’t open Personal space. Great idea, but I think it still needs quite a bit of work.

### 5/5 — Apple should take notes

*2025-10-07*

This has several features apple promised but never delivered, it has a few hiccups since it just launch but is great overall
