Study Ratna 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 the Study Ratna APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. It is signed with a debug certificate, which is meant for testing, not for published apps. After downloading, check that the file's MD5 is d0ce85161e724c7b45b4e4d40d00610d.
