Q: Where I can download Tumblr app for iOS 6.1? In Store, they have Tumblr app only for 7.1 and higher. Thanks!

You can try the information in this support document, Install the latest compatible version of an app on an earlier version of iOS or OS X - Apple Support  but that will only work if the older version is still available from the developer. What iPhone are you using that needs iOS 6.1?

There is currently no way to download older versions of applications.

Hi Just like Apple ios the Apps get updated the old one will be no longer available . Cheers Brian

Yes, there is a way to download older versions if the developer choses to make them available. Please read the link in Chris's post just above yours.

Go to the link in my post. IF there is an older version available, you will be able to access it that way. If not, there isn't anything you can do. As mentioned, it is the decision of the app developer to determine what versions they keep available, not Apple.
