Turn Your iPhone into a Desk Clock: Fullscreen Faces with a Seconds Hand

Published 21 July 2026 · 3 min read · by Chalplex

Turning an old iPhone or iPad into a desk clock only really works if the clock itself is worth looking at, and most built-in options don't show a sweeping seconds hand at all. A proper fullscreen clock with seconds iphone app fixes that, and I've paired mine with a second app for anyone still learning to read a clock face in the first place.

One is built for adults who just want a clear, attractive clock on a spare screen; the other is aimed at children practising the basics.

A Fullscreen Clock with Seconds iPhone Owners Can Actually Use

An old phone propped on a desk or bedside table is wasted if the screen only shows a lock screen clock with no seconds hand and no way to change how it looks.

2 Clocks turns your iPhone or iPad into a fullscreen analogue or digital clock with a genuine sweeping seconds hand, fifteen different faces to choose between, and Home Screen widgets that can show two timezones at once. It works in light or dark, portrait or landscape, so it suits a bedside table just as well as a desk stand.

Learning to Read the Clock, Not Just Look at It

Displaying the time is one thing; understanding it is another, especially for children still working out how the hands relate to each other.

Clock Out teaches time difference through fun maths games, turning the abstract idea of hours and minutes apart into something a child can practise repeatedly rather than just be told once and expected to remember it. It's a natural companion to a fullscreen clock once someone's ready to move from watching the time to actually understanding it.

A clock worth glancing at and a clock worth learning from serve two different purposes, which is why they stayed as separate apps rather than one crowded one. Either works well on an old device that would otherwise just sit gathering dust in a drawer.

2 Clocks is free with ads and shows a fullscreen analogue or digital clock with a sweeping seconds hand; a one-time purchase removes ads and unlocks all fifteen faces.

Is there an app to help kids learn to tell the time on iPhone?

Clock Out teaches time difference through fun maths games, giving children a way to practise reading and comparing times rather than just memorising the clock face.
