Product Description


The Groclock is one of our most highly recommended products. Parents have always struggled with children who are early birds and until the Groclock we didn’t have a reliable solution. The Groclock has an amazing success rate with teaching children to sleep in. Or if they don’t sleep longer, they do learn to stay in bed and not wake up their parents!

How does the Groclock work?

How do you get your children to understand when it's time to get up? It's easy- “stay in bed until the blue sleepy time stars and hearts have disappeared and the screen turns yellow. The sun will have woken up and it's wake up time for you too.” 

The Groclock uses fun images to communicate when to go back to sleep and when it's time to spring out of bed. For older children, they can learn to read the digital time, as well as looking for the sun to wake up. You can also choose to set an optional audible alarm as your child gets older.

Blue Light

There is a lot of information out there around the affects of “blue light” at night on sleep.  The blue light discussion generally relates to blue light waves emitted from LED screens of TVs, computers, smartphones, video games and some light bulbs. When we’ve asked our customers for feedback about the Gro Clock’s blue illuminated face the responses suggested that it has little or no negative impact on their child’s sleep.  

However if it is a concern and you still want the benefits of a reliable sleep trainer clock you can adjust the brightness of the screen. If you don’t want the blue light visible at all at night (e.g. your child prefers sleeping in the dark) the Groclock can be adjusted to “00” which means no light at all, right up to the brightest setting which works well as a nightlight. 

When it’s time to wake up the Groclock's screen will light up in yellow and the sun icon will appear. 

Please note - The sleep trainer clock is powered by USB cable (1.8m length) so there’s no need for batteries. It excludes adaptor plug but compatible with most USB plugs used as phone chargers. We suggest using a good quality adapter to power your Groclock.

How to Use

Frequently asked questions

If the power is turned off, does the Groclock remember the correct time?

When the power goes off, the Groclock freezes all its settings, including the main time, wake up times and brightness. If the power goes off for a few seconds and then comes back on there will only be a few seconds’ difference. But if the power was off for a longer period of time, then the time will be out by the same length of time and you will need to reset the Groclock.

How is the Groclock powered?

The Groclock is mains powered using a 3.5mm (1.8m length) micro-USB cable and adaptor plug. The adaptor plug is not included when you purchase a Groclock, but the included micro-USB cable is compatible with most USB plugs that are used as phone chargers.

If I need to keep the power on to maintain the correct time, won’t that use a lot of electricity?

No, your Groclock uses LEDs so it’s naturally energy efficient. It also has a built–in energy saving mode. One hour after the wake-up time, the clock automatically turns off its coloured LED lights and runs on a tiny amount of electricity. Just press any key and the colour LEDs will come back.

What is the difference between the night–time and day–time nap mode?

Your Groclock clock works the same way in both night-time and day-time modes. Once you’ve set the getting–up time, the clock will count down and Ollie the Owl will wake up at the time set in each mode. The Groclock has a night-time and day-time mode so that you can set different times for your child to sleep during the day and at night, and save having to reset your Groclock every time you want them to go to sleep.

Can I make the alarm sound at any time and in any mode?

Yes. You can set the Groclock alarm separately from the night–time or day–time nap modes. For example, you can have the sun coming up silently at 7am and then the alarm sounding at 7.30am.

How do I know if the audible alarm will sound?

An alarm bell icon appears alongside Ollie the Owl when the alarm is switched on.

How can I stop my child from playing with buttons and changing the settings?

Very easily, by using the key–lock function, which is similar to the function on mobile phones.

Is there a demo mode so I can show my child how Ollie the Owl changes from day to night?

Yes. There is a built–in demo mode which runs through all the Ollie the Owl transitions. Press and hold the UP button for three seconds and the clock will show all the transitions on a continuous loop. To turn off the Demo mode, simply press and hold the UP button for three seconds.

My screen has frozen and is not responding to any controls.

Switch the clock off at the mains, wait a few seconds and switch back on.
