### 4/5 — Advise

*2025-08-09, version 1.4*

Can you make it change color

### 5/5 — ディ・モールト！ベネ！

*2024-08-16, version 1.4*

教科書に出てくる化合物はほとんど作れるのでありがたく使わせてもらっています。構造式が描けるアプリを探している方にぴったりです。欠点を挙げるとすれば、ナトリウムやカリウムといった金属元素が使えないことと、ニトロ基とスルホ基が−NO₂と−SO₃Hで表せないことぐらいです。

### 4/5 — What I expected

*2022-03-22, version 1.4*

No adds, just a nice little tool for typing down some ideas when I am commuting. Sadly ferrocenes does not seem to be possible, but that is quite niche. And maybe some templates and a grid for angles might be a good idea. 3D would be awesome, but I know, how difficult this is to implement.

### 5/5 — Love it

*2021-12-02, version 1.4*

Easy to draw chemical structure.

### 1/5 — Nada intuitivo

*2020-12-09, version 1.4*

Sem menus no App, conforme toca a tela exibe composto qualquer.

### 5/5 — Interessant

*2020-10-30, version 1.4*

Sehr interessant

### 5/5 — Great app but could use a few extra features

*2020-05-19, version 1.4*

I’d like to make an animation on ionic bonding but sodium (Na) isn’t an option. Please add a wider selection of atoms to choose from. Also, please allow for use of ions greater than +1/-1 without a pink X going through it. Same for Hydrogen cations and anions (H+/ H-). I want to show an acid protonating another molecule without a random pink X in my animation. Other than these requests, this is a wonderful app and I applaud you for the easy to work with design.

### 2/5 — Manque de fonctionnalités

*2020-04-21, version 1.4*

Le principe de l’application est super, pouvoir dessine des molécules simplement avec le bout du doigt est génial. Je pense seulement qu’il manque des fonctionnalités telle que pouvoir ajouter les doublet non liants, les charges sur les atomes ou les radicaux !
Dommage que l’on ne puisse pas non plus écrire de réaction avec des flèches pour les mécanismes...

### 5/5 — Awesome app for drawing organic compounds

*2019-11-21, version 1.4*

I have no complaints! This is awesome, especially for being free! There are still a few things one could add or improve, which I would love to see in a pro version (which I would gladly pay for)!

### 5/5 — PC版でも珍しいほどの使い心地

*2019-09-28, version 1.4*

今まで見たことがないほど直感的に操作できます。ヘテロ原子を複数回タップで選択するというのが特に目から鱗でした。なぜこれほど評価数が少ないのか気になるほどですが、これから伸びるのが楽しみです。
