User reviews

Best mobile molecule maker Eva

Definitely the best molecule maker that I’ve seen on the App Store in a while. It lets you use any element, use positive and negative charges, and even name custom molecules that don’t exist in pubchem library! Would recommend to… everyone 😃

Problem with saving as a file

I tried to save the file in my ICloud but it keep saying that Network connection failed, Although My connection is okay. Also before that, it kept saying OSS key access you provided is not enabled or something like that.

Ridiculous

Long time ChemDraw user and thought I would try something free. This is horrible. Not intuitive at all. Just terrible to use. Don’t waste your time

aaaaa

特别好用

Amazing

Easy to use, perfect for organic chemistry
