### 1/5 — Glorified notes app

*2026-07-25*

I downloaded this thinking I could journal and then get some insights on what I’ve written.  The app also lists an AI that you can tailor to you. The only part of the app that works is the journal.  No part of the AI functions, I’m going to be deleting mine since my phone already comes with a notes app and I don’t need two.
