Please don’t buy it!

The app is a joke. Don’t buy it unless you want to waste your coins. It does nothing even the things highlights in the preview. I love chemistry apps. Unfortunately most of them are prepared by scammers. This is one of them. They don’t provide what they showed in the preview.

I wish I can show you the pictures what the app can do. I tried to past some pictures in this review. But it didn’t allowed me to do so.
