quite reliable useful to backup most (but not all) apps prior to installing an updated version. occasionally FC's. Doesn't run in background or eat battery. highly recommended. Doesn't resize to fit tablet screen and not especially pretty, but it's only used occasionally so that's not a big deal. Still runs under KitKat. Still useful.
Great, reliable, multi-version backup I've used this a lot. Several times I've gone back to a backed up older version. A life-saver!
Great app Reliable app that just does what you want to do.
