Android - How can you tell which version of an app is on your Android phone?

Go to Settings > application settings > manage application then tap on the app. It'll say the version you are running under the name. You shouldn't have to check though; If the app in the market doesn't say "Installed" then you don't have the most recent version.

Play app

Android 5.1.1 Xperia Z3:

• find app

• permission details

• right at the top is shows:

  Version XXX can accesss
  

Note: this may not work for some "magic" apps, like the Play App itself.

Device settings

Settings > Apps > Downloaded > App name

and the version is shown at the top of the screen.

I was not able to search by the app name, so get ready for some scrolling.

Going under Running instead of Downloaded did not work: if you find your app there, it shows only runtime stats.

adb

Better method if you've got it setup.

Discussed at: https://stackoverflow.com/questions/11942762/get-application-version-name-using-adb

The best command so far is:

adb shell dumpsys package com.google.android.apps.photos | grep versionName

How to get the package name: View app's full package name?

But this method is not perfect, as they can give multiple results because of the Hidden system packages: section.

Feature request for Google Play Store

Those would be ideal places for it:
