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. No longer runs under Marshmallow, S7 edge :(
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.

Fine on old HTC G1/(GSM plan only) NOT GOOD on Droid 1w/CDMA ON. FC loops when loading apk.files.several attempts. Was able to get 10-20apps backed up
