Chemistry APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is Chemistry free?

The APK is free to download, but the app offers in-app purchases through Google Play.

Is the Chemistry APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. It is signed with the same certificate as the other version checked. After downloading, check that the file's MD5 is d9ef9c77cf16722ec980db760eca552c.
