Senior phone or locked screen — what is the difference?

Four options tend to come up when an ordinary smartphone stops working for someone. They solve different problems, cost different amounts and need different amounts of upkeep. Here are the differences, plainly.

The four options, briefly

This is what there is to choose between today.

  • Picture landline: buttons with photos, sitting on a table. Simple and stable, but tied to one room and useless outside the home.
  • Senior mobile with speed-dial buttons: sturdy, often with physical keys, but the speed dials are numbers rather than faces, and the menus behind them are still there.
  • An ordinary smartphone configured by hand: costs nothing extra, but somebody has to maintain it, and one update or one wrong tap can undo the setup.
  • A locked calling screen on an Android phone: the phone becomes a calling screen with faces and cannot leave it. That is what CallByFace does.

What they cost

Prices vary, but the order of magnitude is roughly this: a picture landline usually runs from around a hundred to a few hundred pounds or euros. A senior mobile typically costs somewhere between a hundred and three hundred. Configuring an existing smartphone costs nothing in money, but takes time every time something changes.

A CallByFace licence costs {price} once per phone, and the phone can be one you already own. It is the only option here where the hardware is not a new cost.

What they handle in practice

Ask the questions in this order and the choice usually makes itself.

  • Does the phone need to work outside the home? That rules out the picture landline.
  • Are faces what is needed, rather than names or numbers? A senior mobile rarely covers that.
  • Does the person tap into settings or apps by mistake? Then a locked mode is needed — a hand-configured smartphone can always be navigated away from.
  • Does the person still need texting, banking or a browser? Then a locked screen is too narrow, and an ordinary phone is the right answer.

Who keeps it running

This is the point that usually decides things over time. A picture landline needs almost no upkeep. A senior mobile generally keeps working. A hand-configured smartphone needs someone to check regularly that nothing has changed.

A locked screen looks after itself in daily use, but photos and numbers are added by a relative or staff member through an admin menu. In CallByFace it opens by tapping the top bar ten times.

Common questions

Can you combine two of them?
Yes, and it is common. Many households keep a locked calling screen for everyday use and an ordinary phone in another room for banking and texting when help is at hand.
Can it be undone?
Yes. A phone running CallByFace can be reset to an ordinary Android. Nothing is permanent.
Does a locked screen work on iPhone?
No. Apple does not allow an app to take over the phone that way, so locked mode exists only on Android.
Does any of these replace a personal alarm?
No. None of them is an alarm system, and none replaces emergency services or a monitored personal alarm.
