Tommee Tippee Groclock vs Connected Sleep Trainer

Both Tommee Tippee clocks can show a silent light or sound an alarm, and both need the plug to work. Groclock is set on its own buttons; Connected is set up and changed in the Tommee Tippee app over Wi-Fi, which lets you change it from another room and adds sleep sounds, a nap timer and several alarms.

Groclock is set on the clock; Connected needs the app and an account

Groclock is set entirely on the clock, with no app, account or Wi-Fi, and its saved times run without the internet.

Connected Sleep Trainer is set up in the Tommee Tippee Smart app, with an account and Wi-Fi. You can then change it from your phone or on the clock itself.

A nap wake-up time, or a nap timer and several alarms

Groclock stores separate wake-up times for the night and for a daytime nap. You switch each mode on at the clock, and the light changes at the time you set.

Connected starts its night when you press the Sleep button on the clock: Tommee Tippee keeps that one control off the phone on purpose. The morning comes from up to four alarms, each set in the app for the days you choose, and a double tap on the same button starts the nap timer. Tommee Tippee does not say whether the wake-up light itself can differ by day.

Both remember their settings but stop in a power cut

Groclock freezes its time and settings during a power cut, so its clock falls behind by the length of the cut. Connected keeps its settings and its link to the app, but Tommee Tippee does not say it runs while unplugged.

Tommee Tippee does not say whether Connected’s saved times keep running when the internet is down. If the clock must keep working, and stay easy to change, without the internet, Groclock is the safer choice.

Connected adds sounds; Tommee Tippee does not say if it needs a subscription

Connected has built-in sleep sounds; Groclock has none. Groclock’s time display can be switched off; Tommee Tippee does not say that Connected’s can.

Groclock’s wake-up light needs no subscription. Tommee Tippee does not say whether Connected needs one, so the matcher leaves it out when you need a clock with no fees.

Buttons or app, and how each does naps

Choose Groclock for account-free local controls and a second clock-time mode for naps.
Choose Connected for changes from your phone, a nap timer, several alarms and built-in sounds.
Neither keeps running on a battery, and both come with a USB cable but no wall plug.
