### 3/5 — Low Quality

*2026-02-22*

No creatures availble in dive logs 🤷‍♀️ tried to log, list empty

Lack of species (237) and weak ui (tell you that as a UX specialist, guess this is a one-prompt AI generated app)

Feels like a cheap copy of seabook

**Developer response:** Hello Chesseea! Thanks a lot for sharing your experience and feedback about the app. We really appreciate honest feedback. It is true we don't have all species, there are still a lot to add! About UI/UX, you're right, we are learning daily and trying to improve the experience. We would love to hear more about what was confusing inside the app and what we could improve to make Thalio easier to navigate.

### 2/5 — Poor quality and buggy

*2026-01-16*

Tried switched to it, as it was easier to log what I saw. But… recently my collection just gone away. Not recommended

**Developer response:** Hi! I'm really sorry that this happened to you!! This should not happen, and I understand your frustration. Could you please tell us more about the steps you followed for this to happen?
