Tinitell is a wearable mobile phone for kids. A wristphone that enables peace of mind for parents, and lets kids be kids.

About this project


Tinitell works in every country in the world! (except N. Korea, S. Korea and Japan). Check out our FAQ for more information about subscription offers from network service providers.


Features And Functions


Tinitell is a Scandinavian designed and engineered mobile phone and we have intentionally stripped it down to feature only the most basic functions. Our philosophy: It should perform well and look cool — without being too pricey.

Managing Your Tinitell

Once you receive your Tinitell, insert a voice-ready SIM card of your choice (check out our FAQ for subscription options). If you have a smartphone, you can download our app (iOS / Android) for easier management. You can also manage your Tinitell from our website. 

 Making Calls

Your Tinitell is equipped with voice recognition software. To make a call you just push the button on your Tinitell, say the name you want to call - and the call is placed!

You save the contact list for your Tinitell on our app or website, which gives you full control of all the numbers your Tinitell can call. You can also monitor what calls are being made through the app or via the web.

If you don't want to talk with your Tinitell and use speech recognition, you can use the volume buttons to scroll through your Tinitell's contact list (Tinitell will play the recorded names accordingly). When you've reached the number you want to call, for instance "Mom" or "Dad", you just push the button and the call is placed.

Receiving Calls

Tinitell can receive calls from any telephone number, simply press the button to answer incoming calls.

It is easy to administer the telephone numbers that can call your Tinitell. You can limit incoming calls to a pre-defined set of telephone numbers from our app or website. You can also assign numbers that will be answered automatically by Tinitell, without the user having to answer with a button-push.

In short, the app and web dashboard give you full control — and piece of mind. Finally your kids can be outside exploring as kids should be. 

The App

It’s easy to position Tinitell from the app or website. Simply select which Tinitell you want to position, and see where it is on the map! Only the Tinitell administrator can position a specific Tinitell, but you can enable administrator access to others (for instance to neighbours or babysitters) if you want to.


Why are we turning to the good folks of Kickstarter to help us make this product come to life? Obviously we love technology and design, but being Scandinavians, we have this great love for the outdoors as well. Just look at how Amy digs into life when she is outside.

When possible, we want our kids to go outside and play. That's why we designed an affordable and durable product for a market that would otherwise only offer the same functionality in bulky or uncomfortable casing. Tinitell is wearable and enables play like no others!

... and we thought: Are we the only ones longing for a product like this? Maybe the Kickstarter community is as passionate as us and maybe even they want to put the Tinitell into production?


Please note: All rewards are subject to local VAT and import tariffs if shipped outside of the US. 


We want to get Tinitell in the hands of developers earlier than anyone else because we want make the final consumer version of Tinitell even better than it currently is. You'll get Tinitell's SDK if you want to re-program Tinitell, and make it awesome your way! Check out the rewards geared to you tech savvy artists.

"Best addition to the field I’ve seen so far. Nice work.” - Richard Feigin, Founder Creative Mornings

“My daughter is going to love it." Jeff Brecker, Managing Director RGA

Tinitell has been lauded as Sweden's most promising tech start-up in 2013, and the project is supported by Royal Institute of Technology in Stockholm.

We have also been granted funding by Vinnova for being one of the most innovative companies of year. We have invented and patented a new way for multiple devices to communicate in sync with each other.


We want to be transparent about the production cycle. It will be worth the wait, but we have researched various production alternatives so we know exactly how long it will take us before we can ship a Tinitell to your home! This is what has happened the past few months, and where we are heading.

Risks and challenges

Building a new kind of ”world’s-smallest” mobile phone is complex and time-consuming. We are humble to the challenge, and we know there are many pieces that will need to be put together for it to work. Getting to the point where we can ship Tinitell to your door from the point we are at now, involves the following:

1) Finalizing the design and construction for production. All the components must fit together, literally water tight. There is so much to take into regard when finishing this up. Fortunately, we have the construction experience of one of the formost plastics manufacturers to rely on, as well as the hardware experience from our ex-Sony Ericsson, CTO, Peter Lorentzon.

2) Fitting the electronics into such a tiny shell. This is no small feat. Even though we have functioning prototypes we are still working on the development of the mobile phone. Reconciling the technical requirements of a GPS system, GSM system, and a minature computer in the size of a square inch is demanding. We have two very experienced hardware engineers on our team to make this happen.

3) Setting up a logistics and quality assured manufacturing chain. In every step of the production, our manufacturers need to have strict guidelines and tests to sort out the good units from the bad as early as possible. To assist us with this, we are leveraging the knowledge of people that have done this multiple times in projects before Tinitell.

4) Getting all the pieces of the firmware in place and working without problems. There is a big difference between having a functioning prototype that makes and answers phone calls and gathers GPS data (which we do) and having it function properly under adverse conditions out in the field. Again, our team members have built both hardware and firmware for mobile phones before.

We are not shying away from any of these challenges. While we take them seriously we are determined to overcome any problem. We are committed to getting Tinitell on the market (lots of kids and parents need them) and have all the skills needed to do so. With the help from the Kickstarter community we can have the resources to move into production while also completing all of the tasks above!

  • Your pedge is a one-time expense to us. Tinitell is an unlocked mobile phone. To be able to use Tinitell, you will need to install and pay for your own SIM card and service subscription. Tinitell is built on a 2G platform (GSM 850/900/1800/1900 MHz), and works in any country in the world, except N. Korea, S. Korea and Japan.

  • To be able to use Tinitell you will have to get your own SIM card and service plan. We don’t offer subscription plans.

    The most suitable plans for Tinitell, as we see it, are the pre-paid or pay-as-you-go plans. In most countries they usually cost around 10 USD per month and should cover your calling and positioning needs.

    We see Tinitell as a new solution for making quick calls and positioning, which is why we recommend the smaller subscription plans.

    Here are links to service providers that offer pre-paid subscriptions that will work with Tinitell.













    Other Countries

    Tinitell works anywhere in the world, except N. Korea, S. Korea, and Japan.

  • To be able to position Tinitell the user must use the Tinitell app. When you request Tinitell’s position from the app, the position request is sent to Tinitell. When Tinitell is given the request it retrieves its position from the GPS satellite network. When Tinitell has its position, it sends it back to the smartphone app. That way, parents can position their wild ones, and see where they are.

    And technically speaking, how does Tinitell communicate with the smartphone?

    There are two ways Tinitell will communicate with smartphones. The first way is by data traffic. That is by far the cheapest. The amount of data involved in sending a GPS is very small. There are some plans that do not support data, however. If Tinitell is not able to send the position data via a data connection, it will send it via SMS.

    Last updated:
  • Forwarding calls will be made available by our development team when we ship Tinitells in April. You can use the forwarding calls functionality so that you can leave your smartphone in your pocket, or you can leave your smartphone at home! Tinitell is a stand-alone mobile phone that communicates on the 2G cellular network. It has been easy to program call forwarding thanks to a protocol stack standard in all GSM networks world-wide.

  • Tinitell's voice recognition is not "universal", but it does work with any language in the world - even animal languages.

    When the user says the voice-label of the person they want to call, the voice recognition software matches the said voice-label with a pre-recorded voice-label. This way the voice recognition software doesn't have to understand every word and dialect in the world, it only has to match said voice labels with pre-recorded voice labels.

    For this set-up to work the Tinitell user must use the app. For each contact the user wants to have in their Tinitell's contact list they have to pre-record the "voice-label" for that contact in the app. The voice label is then pushed out to Tinitell via bluetooth. We are also looking at ways to push out voice labels via the cellular network, but have not verified that method yet.

    If your Tinitell lacks voice labels then the only way to make calls is by scrolling through Tinitell's contact list with the volume buttons. As the user scrolls through the numbers an embedded text-to-speech software says the name of the contact in question. When you arrive at a contact you want to call, press the button, and your good to go!
