### 4/5 — Dev needs to fix the placement of the Settings View

*2025-03-30*

On the current version, the app opens up the Settings view by default, as the Dev accidentally put it inside of WindowGroup {} instead of Settings {}

### 1/5 — App does not work, I am shown a what I believe to be some start up menu.

*2024-10-17*

When I open the app on my MacBook, some start up menu opens, it asks me for my preferences in units, language, and color, but I cannot leave this page for some reason, I tried restarting, nothing changed.

### 5/5 — Great for students

*2024-06-06*

The interface is simple and easy to navigate. The information provided is easy to read and is thorough enough to make my college level chem assignments fly by. Some nice additions would be 3D atom models and a search element feature

### 5/5 — It’s amazing

*2024-05-26*

It’s the BEST

### 4/5 — Molecule Model

*2023-10-25, version 1.2.6*

Great app overall and amazing UI

I don't understand how you can make molecule models. Would be better if there were a video on a website to show you it's done!

### 5/5 — Fantastic PT for Education and Reference

*2023-10-05*

I teach Sophomore-level Chemistry and AP Chemistry. The table is fantastic for creating assignments and exams. It gives all the extra information I could want about elements, all in one place. This allows me to have freedom to create problems, situations, labs, and more, without using a cumbersome number of sources.

As an educator, the only thing I wish the table had, was a general zoom function. As is, the table is fantastic for personal use. However, it is a little small to read if I were to project it on my screen. Extremely minor wish, compared to the convenient information this table provides.

### 4/5 — Nice GUI

*2023-03-28, version 1.1.1*

Nice app for general use searching through periodic table. Designed more for chemists obviously. A nice add on would be the table of isotopes - A v Z, then it would be better for physicists. I like the electron configuration graphics.

### 5/5 — Great chemistry tool!

*2021-05-15*

I love the color of periodic table of elements. They look clear and comfortable. It does male my chemistry study much esier!! Thanks for the developer 😀

### 5/5 — A very beautiful interface

*2021-05-09*

Very well designed app, especially the carbon nanotube model
