I have recently purchased a Galaxy S5. I would like to root it, but so far, it seems that the "Towelroot" approach does not work on my model (purchased in Japan from Docomo), and other options are at this point too complicated for me.

So, my old phone, an S2, is rooted, but my new phone, an S5, is not.

Cut to today when I discovered that the calorie counter app I preffered, Calorific, is no longer available, and has been replaced with a feature bloated new version that ruins everything I liked about the previous version.

I still have that previous version on my old phone, so, if possible, I'd like to move that app over to my new phone.

Of course, I've looked on this forum for solutions, but [other questions][1] I've seen so far presume either that one's phone is rooted or that one is trying to completely recreate all settings from phone to another.

I would like at this point to just move one app. Is that possible?

My previous phone has Titanium Backup Pro, if that helps. [1]: How to backup an Android device?
