Remote arming/disarming

I don't yet have a Ring system but I'm considering buying the alarm. However through one particular Amazon review I've discovered that (despite what the website claims) the ability to arm/disarm the alarm through the app is only available to subscribers. This seems to be a recent change. I'm not really wanting to sign up to a plan but my question is: for those of you who *do* have this arm/disarm feature, how do you use it and do you consider it important/vital? For example, do you find it convenient to disarm through the app when you return to your house instead of having to go to the keypad?
