Cubo Ai or VTech baby monitor for grandparents who will not use an app?

What does each brand give you to look at?

This is a viewer comparison for a mum or grandparent who will not install an app. It is not a “which is safer” score and it does not reopen DECT-versus-Wi-Fi radio debates.

Why do testers say Cubo is a poor fit for some grandparents?

Mother&Baby’s Cubo Ai Plus panel (page updated 17 December 2025) recorded the exact babysitting problem: one tester said the product assumes everyone has a smartphone and is willing to put the app on it, that some grandparents are not confident with the tech, and that it is unreasonable to expect a babysitter to download the app for an occasional evening. The same tester asked for a dedicated monitor as well as the phone. Other testers liked watching on a phone — including from work — which is the opposite use case.

Which? (August 2021 features guide, still linked from its baby-monitor hub) makes the same industry point without naming Cubo: some smart monitors have no parent unit, so you rely solely on a phone. That is the fork for a grandparent sit: app-only versus handset-in-the-drawer.

Cubo’s current UK page still states Wi-Fi is required and a smartphone is required (iOS 16 / Android 9.0 or newer on the Monitor 3 footnotes). That is a product fact, not a judgement of any grandparent.

When is a VTech parent unit the simpler sit?

When the person in charge will not unlock an App Store account. A non-Wi-Fi VTech video set (Which? examples: VM3254, VM3263, VM7367HD) is a camera plus a charged handset: volume, LINK light, optional night light on the baby unit. No cloud login. Which? also tests VTech models that do add Wi-Fi (RM5766, RM7766, RM7766HD). Those still include a parent unit, so a grandparent can ignore the app and use the screen — as long as someone else finished any Wi-Fi pairing beforehand.

1. 1
   Ask who will hold the viewer If the answer is “whoever has their phone”, Cubo’s design matches. If the answer is “the handset on the kitchen side”, pick a set that ships a parent unit.
2. 2
   Ask whether the house Wi-Fi is trusted Cubo’s UK FAQ requires a stable, password-protected network (they mention 5 Mbps and WPA/WPA2). A grandparent’s cottage with guest Wi-Fi is a poor Cubo site.
3. 3
   Do a five-minute handover For VTech: show POWER/LCD OFF (screen off, sound on) and the LINK light. For Cubo: show how to open the live tile and who owns the login — or do not leave Cubo as the only viewer.
4. 4
   Leave a no-app backup if Cubo stays Mother&Baby testers mentioned keeping a cheap plug-in monitor for travel and for people who will not use the app. That is a household workaround, not a brand ranking.

Does a handset make one brand safer than the other?

No. Which? tests picture, sound, range, battery and (on Wi-Fi models) security. The Lullaby Trust says monitors do not prevent SIDS and do not replace a carer in the room. Cubo’s AI alerts (covered face, rollover) and VTech’s simple night vision are feature lists, not a clinical ranking. This page only answers: can a grandparent watch without an app? Cubo’s published answer is no. A typical UK VTech video box’s published answer is yes, via the parent unit.

In shortApp-and-Wi-Fi (Cubo) versus handset-you-can-lend (most UK VTech video sets). Choose the viewer the sitter will actually hold. That is not a safety verdict.

What still applies whoever sits?

Cables out of the cot, camera fixed so it cannot fall in, and a plan if the picture dies. The Lullaby Trust baby-safety helpline is 0808 802 6869. If the baby does not respond, call 999.
