As of August 2026, the top pages that answer this exact question give almost the same list of steps as each other, and none of them says when to reach for which one.
Cake points toward hiring a geriatric care manager. Growing Gray lists five things to try, unordered, ending with a call to the police. An AgingCare forum thread suggests giving a neighbor a house key and paying them a daily stipend to look in on your parent personally. I'm Alive, itself a competing daily check-in app, argues the anxiety is the real problem, and that most missed calls mean something harmless. All of that can be true at once and still leave you standing in a kitchen at minute forty with no idea what minute forty is supposed to mean. Read together, the pattern is unmistakable: every one of them agrees on the toolbox, and none of them sequences it. What follows doesn't replace calling 911 the moment you already know something is wrong; it's for the far more common case where you don't know yet.
It has been zero to two hours
A missed call in this window is almost never the story anyone fears. A parent who's dozed off, in the shower, or has Do Not Disturb on by accident explains most unanswered calls, and none of it needs a stranger involved yet.
Try again once or twice, spaced a while apart rather than stacked back to back. Five calls inside five minutes reads as one missed call to whoever eventually notices the phone. A single text saying you called gives them something to answer once they do notice.
Cost: nothing. No one else needs to know yet.
It has been two to six hours
This is the window where it's worth glancing at whatever you already have set up, without calling anyone. Our guide to the free Android signals covers how to turn each of these on; here they're ranked by how much each one tells you rather than by how easy it is to glance at.
A text sitting on delivered without turning to read is the most useful of the four, because Google's own documentation makes read receipts something both people have to opt into, while a delivered marker reflects something closer to the network's real-time state (per Google's RCS chats FAQ, current as of August 2026). Below that is a last-seen indicator in whatever messaging app she uses, telling you when the phone was last opened rather than whether she's fine. Below that is the timestamp on a shared-location dot, since a location shared an hour ago carries different information than a pin frozen since last night even when the map looks the same. Least useful is Find Hub's last-known-online time, which only updates while the phone still has a connection, so a phone that's been dead since dinner and a phone that's simply stepped out of Wi-Fi range for an hour can show the exact same stale timestamp.
That order is a judgment call rather than a fact, and it rests on one specific piece of sourcing: because read receipts require both sides to opt in, a message parked on delivered could mean she hasn't glanced at her phone, or it could just as easily mean read receipts were never turned on to begin with. The icon alone can't tell you which.
And that's the ceiling on all four signals together. A phone that's switched off, one with a dead battery, or one sitting with no signal all produce identical evidence from where you're sitting, so none of these checks can tell them apart. That's the whole reason this rung ends in a decision to wait a little longer instead of a diagnosis.
Cost: still nothing. It spends the ten minutes you'd have used refreshing your phone anyway.
It has been six to twelve hours
Past six hours, waiting stops being the obvious default, and the ladder shifts from checking screens to asking people. Call whoever is closest and would notice something off: a neighbor, a building manager or super, the friend she plays cards with every week. Ask them to look in on your parent in person rather than phoning the house themselves; a second unanswered call tells you nothing new.
This rung costs something real, even when it turns out to be nothing: someone's afternoon, and a small debt of gratitude you'll owe them whether or not it was warranted. Weigh that against what you're afraid of before you spend it, and be plain with the person you're asking, so they know it might be nothing.
If what's keeping you up isn't a silent phone but the fear of a sudden medical event, a fall, chest pain, a stroke's first slurred sentence, this whole ladder is the wrong shape of tool, because it's built around elapsed time rather than an alert that fires the moment something happens. A monitored medical alert pendant with a live dispatcher is built for that fear instead: press a button and a person answers, with no hours to wait through first.
Medical Guardian's basic in-home plan runs $27.45 a month on an annual plan, with automatic fall detection available as a $10-a-month add-on (per Medical Guardian's own pricing page, checked August 2026). That's real money for a device that only helps while it's being worn, but it buys something an elapsed-time ladder cannot: a person on the other end of a button before a single hour has passed, let alone six.
It has been twelve hours, or something already feels wrong
Twelve hours is roughly where the outside advice on this converges on the same last resort: a call to your local police department's non-emergency line, asking for a welfare check. Call sooner than twelve hours if something else about the day is already off: a plan she confirmed and then went silent on, or a pattern that's new for her rather than an unanswered call in isolation.
What an officer typically does once that call is made, whether forced entry is on the table, how to ask for a callback: that's covered fully in a companion piece on requesting a welfare check. What belongs here is only the decision to make the call at all, and the fact that a false alarm at this rung is a survivable embarrassment, while a real one delayed past it usually isn't.
A ladder like this only exists because most families have no baseline for what's normal, so every gap in contact gets re-litigated from scratch, by hand, under stress. A passive signal that simply notices when a phone that's normally used has gone quiet removes that guesswork instead of replacing the ladder outright. It's the specific gap our own dashboard at CareBridge is built to sit in, for the families who want one less thing to reason through at hour three.
The ladder, to screenshot
Save the shape of it, not the exact hours, since your own read of "normal" for your parent should move these lines around:
- Zero to two hours: try again, spaced apart, then send one text.
- Two to six hours: glance at delivery status, last-seen, location timestamp, and Find Hub, in that order.
- Six to twelve hours: ask someone nearby to look in on them in person.
- Twelve hours, or something already off: call the non-emergency line for a welfare check.
