General :: Automatically Disable Screen Lock At Home Or Work

Is there a simple setting that will automatically disable my screen lock when I'm at home or at work? If not a setting, is there an app you recommend?

Long version: I'm fairly new to "devices". I got my first, a wifi-only Samsung tablet about 6 months ago and use it sporadically, mostly when traveling, but also it's become my semi-permanent music player at home. I got my first smart phone, a MotoX about 2 weeks ago. Love the MotoX and feel it's exceptionally well designed, easy to configure, and useful, but I have nothing to compare it to other than my wife's IPhone 5.

I have done a web search for this information. I have also searched and scanned around these forums, but didn't find anything I felt comfortable with in terms of how fussy or current the set up steps are or how current the app recommendations are. The two apps I've come across are, IIRC, called "Delayed Lock (trial or paid)" and "Unlock with WiFi".

My question is - today, mid-October 2013 - how do you recommend disabling screen lock while at certain locations. I imagine I'll be using it strictly at work or at home, both of which have wifi I connect to automatically. I might want to disable screen lock while driving, but so far have found my MotoX's Assist driving mode to work very well. I might get a Bluetooth device and at that point would probably want to disable the screen lock while that bluetooth device was connected.
