In case you needed someone nagging you to get a certain chore done, Google Now has an occasional reminder feature that lets you set recurring alarms for a particular task. It can also be a one-time reminder based on your time or location (like it will remind you to buy milk if it senses you are inside a supermarket). We’re not sure how frequently the alarm will sound off but if you really need that extra push, this might be a good feature to utilize.
