I downloaded App Lock for Android and have been using it for a couple of days on my Moto E (2nd Gen) Lollipop v5.1. App Lock seems to list all apps on my phone as available to lock except for the "Google Settings" app (not the phone "Settings" app). Is there a reason why the Google Settings app is not included in the list?
Also, as a suggestion for future releases, would it be possible to allow longer PIN codes, e.g. up to 6 or 8 digits? It would also be nice to provide the ability to use alpha-numeric pass-phrases or pattern locks in addition to PIN codes.
Keep up the good work. I'm looking forward to future releases of the App Lock app.
