I’m stingy with notifications and use Focus and DND on my phone.
My active notifications are limited to Phone, Messages, Reminders, Find My, Clock, my bank app, my CGM apps, Nest, and Waze (for “time to leave” notifications only). Beyond that, I allow a few other apps badges, just so I know when they have something to say without being actively bugged by it. I turn on notifications for certain messaging/communication apps (FaceTime, Messenger, WhatsApp, etc.) only when I’m expecting a ping that I don’t want to miss, and certain other apps when using relevant functions (like DoorDash, Uber, and RunPee (an absolute must for moviegoers with overactive bladders!)).
Then I use Focus and DND to keep those apps’ notifications to a minimum when I’m doing something important (like working or sleeping). I always let notifications from my spouse and my elderly mother through. Medical providers are allowed during work, but not overnight. Everyone else can wait.
I also am very restrictive about allowing websites and services permission to text me. No, I don’t want you to send me marketing texts, ever. Marketing emails I’ll allow, because I don’t have email notifications active on my phone. But there is no “special sale” that is ever important enough to me for you to interrupt my day with a text message.
The one that frustrates me is my CGM. The official Freestyle Libre app cannot be completely silenced by Silent Mode, Focus, or DND. It offers a “silent delivery” mode, but it limits that to six hours at a time, which won’t last me through a full night’s sleep. (And “silent delivery” actually will generate spurious notifications that remind you you’re using “silent delivery”, just to make it worse!) I use a CGM only to monitor my hypoglycemic diabetes; I’m not on insulin, and my body will release more glucose after a sharp drop, just more slowly than it should. So I’m not going to go into a hypoglycemic crisis while I’m sleeping, and most nighttime low alerts are actually due to an unavoidable flaw in the design of CGMs (continuous pressure, such as when laying on them, can cause them to produce false low readings), not genuine low glucose episodes.
My only recourse for this is to turn off notifications for that app when I go to bed and turn them back on in the morning. I don’t use that app for my primary source of casual readings anyway—I use a third-party app called Sweet Dreams, which relies on the LibreLinkup feature that allows you to share your readings with family members, for that, because it offers a wider variety of alerts and actually has a widget and Live Activity. (Why any CGM app wouldn’t include a widget baffles me. Why should I have to unlock my phone and launch the app just to quickly check my glucose level?) But because LibreLinkup relies on data from a third-party server, it’s not reliable enough to leave the official app out of the loop entirely.
Everything else? Screw you, app. I don’t ever need notifications from a game app. I don’t want news alerts. Social media is for when I actively want to engage, only. If I want to know about a sale at some store, I’ll check it directly. Y’all can wait until I actually launch you.
