The question every parent facesIs my child ready for a smartphone — or is there something in between?
Why we created KidNavi
Because Growing Up Should Feel Safe.
KidNavi was created by parents, for parents. Like many families, we wanted our children to enjoy more independence, but we weren't ready to hand them an unrestricted smartphone, with open internet, social media and endless screen time.
So we looked for something in between: a watch that lets children call home, share where they are and enjoy useful, age-appropriate features, while parents keep the reassurance they need.
Reassurance for parents
Location, calls and an SOS button, all managed from one app on your phone.
Independence for children
A first step into technology, built around staying in touch rather than social media.
Shop by age
The right watch for every stage
Every child is different. Younger children need something simple and sturdy, while older children want a design that feels grown-up. Choose by age, then compare the details.
Ages 4–10KN24
Younger children
A first smartwatch with the essentials: GPS location, 4G voice and video calls and an SOS button, in an IP67 water-resistant design.

Why KidNavi
More Than a Smartwatch. A Smarter Way to Grow.
Everything a family needs to stay connected, without handing over a smartphone too soon.
Stay connected
Voice and video calls over 4G, so your child can reach you and you can reach them. Just add a nano-SIM with a data plan.
Know they're safe
See their location in the SeTracker2 app, get an alert if they leave a safe zone, and let them send an SOS alert at the press of a button.
GPS accuracy depends on signal and can be lower indoors.Technology with purpose
Games, learning features, alarms and everyday tools give children something useful to do, rather than endless scrolling.
Features vary by model. See each watch for details.Support you can count on

The watch works reliably and has a simple, user-friendly system. Everything is stable. The easy operation and child-friendly design make it an excellent choice for parents. The location feature gives us, as parents, a sense of security. The sound quality during calls is clear and crisp.

Birthday gift for my 6-year-old daughter and a second watch for my son — they both love them! It was very easy to set up, and my daughter was able to use it right away.

Need Help Choosing the Right Watch?
Our team is here to help you find the perfect KidNavi for your child, and to help with setup once it arrives.
Does the watch need a SIM card?
Yes. Every KidNavi watch needs a nano-SIM with a data plan for calls, GPS location and the app. A SIM isn't included, so you can choose a plan that suits you. Most UK networks are compatible. If you're unsure about yours, message us on WhatsApp before you order.
Which watch is right for my child's age?
KN24 is designed for ages 4–10 and KN25 for ages 5–12. KN30 and KN40 Pro are designed for teenagers, with more mature styling and AI Assistant Jarvis. Compare all models.
How does GPS tracking work?
The watch shares its location with the SeTracker2 app on your phone. You can see where your child is and set safe zones that alert you if they leave. Like all GPS devices, accuracy depends on signal and can be lower indoors or in built-up areas.
How long does the battery last?
It depends on the model and how the watch is used. Video calls and frequent location updates use more power. KN30 has a 950mAh battery and KN40 Pro an 800mAh battery. We recommend charging the watch overnight, like a phone.
Is the watch waterproof?
All four KidNavi watches (KN24, KN25, KN30 and KN40 Pro) are rated IP67 water resistant, so they can handle rain, splashes and hand-washing. They are not designed for swimming, baths or showers.
Is it easy to set up?
Yes. Insert the SIM, charge the watch, download the SeTracker2 app and follow the quick-start guide in the box. If you get stuck, our team can help on WhatsApp, Monday to Friday, 9am–5pm.
How much is delivery, and how long does it take?
Standard UK delivery is £8, or free on orders of £100 or more. Express delivery is £17. Orders are usually dispatched within 1–2 working days (1–3 in November and December), and most arrive within 5–7 working days of ordering.
What if it's not right for us?
You have 30 days from delivery to request a return. Faulty items are refunded in full, including return postage, and unopened items can be returned if you change your mind. Read our returns policy.
