While the “Ok Google” commands require either wifi or data to work, they can be very helpful if you know how to use them. Here are a few examples:
“Do not disturb until [time]”
Let’s say you have a meeting that ends at 12:30 pm, and you don’t want your phone to ring if you get a call or text. You turn on “Ok Google” and say “Do not disturb until 12:30 PM”. The “PM” part isn’t necessary– usually smart phones will figure out what you mean.
“Take me to [address]”
Activates Google Maps and takes you to said address. You can also specify the name of a business, such as “Take me to Arby’s”.
“Set an alarm/timer for [time]”
“Set a timer for [m] minutes”
Alarms are designed to be able to repeat daily or weekly. Timers are designed to be used once.
Either way, you can set them to go off at a specific time. “Set a timer for 2:00 pm” for instance.
You can also do commands such as “Set a timer for 30 minutes”.
These are ones I use frequently. If I learn more I will update.
