Hints & Tips

Cayla will only pair with one device at a time.

Cayla will pair with the device she’s been most recently paired with first. If this is not the correct device, turn off Bluetooth on the incorrect device and re-try. Once Cayla is paired with one device she cannot accept a connection with an additional device at the same time.

What kind of devices/hardware is Cayla’s app compatible with?

Cayla is compatible with smart phones and tablets running iOS and Android operating systems.

The minimum specification is:

  • Memory: 200Mb free space for installing the app. 64Mb free space for the app to run.
  • Bluetooth: 3.0 or higher
  • Android: 4.0.3 or higher. Not compatible with Kindle Fire.
  • iOS: 7.1 or higher
  • Processor: x86-64 or ARM; 1GHz or above.

Where do I get the App?

You can get it either on iTunes app store or Google Play like any other app. Search for “My Friend Cayla” or follow the link at the top of the website.

Is there any charge for the App?

There is no charge to download the app for the primary language in your country. Other language apps (e.g. French and German) can be downloaded for a small charge. Check with the relevant app store for your device to see what’s available.

There are no in-app purchases available.

Are there any monthly services or charges to play with Cayla?

On Android: If you are using Wi-Fi there are no additional charges to play with Cayla. The only possible extra charges could be from exceeding your data limit if you are on a cellular network and not Wi-Fi.  It’s a good idea to use Wi-Fi when playing with Cayla’s app whenever possible as this should give the most reliable connection.

On iOS: Cayla comes with 3000 free voice transcriptions sent over the internet (taking a voice and converting it to text so it can be understood by the app). After 3000 voice transcriptions it will be necessary to add more if you desire. Additional voice transcriptions require a small fee and may be purchased through the Apple App Store. As with Android, there are no data transmission fees for using Wi-Fi.

Note: 3000 voice transcriptions is quite a lot and should be plenty for months and months of play. If someone were to ask Cayla a question every minute, they would not stop for 50 hours!

Internet use

Do I need an internet connection to play with Cayla?

An internet connection will be required to download the free app which unlocks all of the fun things which Cayla can do. Some functions, such as searching for information on the internet (famous people, places, time, weather, etc), require an internet connection. Cayla can do lots offline, like having conversations, playing games, reading stories, and exploring her photo album. In fact, most of the interactive play requires no internet connection at all.

If I am on a cellular network and not Wi-Fi, how much data does she use in an hour?

This depends greatly on how many times she looks for information online.  However, as the information is mainly text and not graphics, audio, or movies, the amount is generally very small.  Still, it is recommended that if you use Cayla’s app you should either have an unlimited data plan or be on Wi-Fi to avoid unnecessary additional charges to your phone bill.

Online Safety

Will my child be safe when Cayla is using the internet?

There are four levels of safety features built in to protect children when using Cayla online.

1) Cayla’s software system, called Violet, checks for any offensive or sensitive words against a pre-set blocked word list. If the question or answer contains any words on the blocked word list Cayla will automatically tell the child she cannot talk about those things.

2) Online safe-search filters will also scan responses for inappropriate content.

3) No website links, images, movies etc. will ever show up in the app. There is no ‘data mining’ or storage of any personal information.

4) Additional words or phrases can be added to the blocked list via the app. Please note that once a word is added to the blocked list this cannot be undone and the list cannot be viewed.

Playing with Cayla

Does the room have to be completely silent?

Cayla’s Violet software can filter out a lot of background noise such as other people talking in the background, air conditioning, TV programs, and other minor noises. Cayla works better when only one person talks at a time.

How far away can I be to talk to Cayla?

The best distance would be close enough to hold the doll or be next to her.  Normally, that’s about 25-40 cm.  But, if you talk louder and clearly, it can be over a metre. It’s important to speak to Cayla like you would another person.  That is, speak as if you wanted someone else in the room to hear what you have to say.

Does she have an On/Off switch?

Yes. Cayla has an on/off switch on her back. Also, you can use the App to stop her program at any time. And, if left alone too long, the app will close itself.

Can I adjust her volume?

In the app there’s a page to adjust not only her volume but how “chatty” she is. If you want her to talk more quietly or want her to talk less you can easily adjust it.

How does Cayla understand what I say?

The Violet software in Cayla’s app uses Google’s and Apple’s voice recognition software. The question asked to Cayla is picked up in her microphone and sent in real time over the internet to a server in ‘the cloud’. There, it is transcribed into text and then sent back to Cayla’s app to be used to answer the question. All this happens in less than one second (depending on the speed of your internet connection). Both operating systems have the best voice recognition capability in the world- and in many languages with many different dialects and accents.

What kinds of things can Cayla talk about?

Cayla can be asked questions about herself (“Tell me about your brother”) or personal questions (“What’s your favourite ice cream?”) or questions about things to do (“Should I paint my nails”).  In addition, you can ask her virtually any maths question (“What’s 22 times 47″?) any question about people, places, and things (“Where is the Eiffel Tower?”), spelling, and even the weather.

Can I change her clothes?

Cayla is compatible with most 18 inch (45cm) doll fashions.  You can change the clothes, shoes, and do the hair like any other 18 inch doll.  She weighs the same as a normal doll.

Can I play games with her?

Cayla’s app comes with different games that the child can play either with Cayla or against Cayla.  More games will be added over time.

Does Cayla ever have "a bad day"?

Cayla is always a warm and friendly person to talk to who loves to laugh and giggle. She will brighten anyone’s day – like seeing any good friend would.


My smart device can’t pair with Cayla when Bluetooth® is turned on

Check that you have downloaded the correct app. The Cayla app will not work with a Chloe doll and vice versa.

Make sure there is only one doll trying to connect to the smart device, and that the doll you are trying to connect isn’t already connected to another device.

Try replacing Cayla’s batteries.

Please refer to the manufacturer’s guidance for your smart device regarding Bluetooth connectivity.

What is the minimum specification for my mobile device?

Memory: 200Mb free space for installing the app. 64Mb free space for the app to run.
Bluetooth: 3.0 or higher
Processor: x86-64 or ARM; 1GHz or above

Minimum operating systems:
Apple – iOS 7.1 or higher
Android – 4.0.3 or higher
Please note: not compatible with Kindle Fire.

The light on Cayla's necklace doesn’t turn on but the app appears to be working.

It’s likely the microphone isn’t turned on. Here are some tips, although these might not be applicable to all devices. We recommend you consult the manufacturer of your device if you continue to have this problem.

Open the Google search app. Open the option selection menu (usually found at the bottom of the screen, probably denoted by three dots). Select Settings and then choose “Voice”. Disable the “Bluetooth headset” setting by unticking the box next to it.

Go to Settings, Privacy, Microphone. Turn on the Microphone option for the Cayla app.

Cayla doesn’t understand my question

Sometimes Cayla may not hear you the first time, especially if there’s a lot of background noise which might confuse her. Ideally you should be less than a metre away from Cayla.

She is capable of understanding languages in different accents, but you need to be clear just like when speaking to another person.

Please be patient and repeat the question again when the light in her necklace is shining.

Make sure there isn’t anything blocking the microphone in her chest. (The clothes she came in shouldn’t cause any interference.)

Here are some recommendations for how to ask Cayla questions:
Don’t start the question by saying Cayla or Chloe’s name. e.g. “Who is Queen Elizabeth?” not “ Cayla, who is Queen Elizabeth?
A Place: “Where is the Eiffel Tower?” “What is the population of Paris?”
A Thing: “What is an aeroplane?”
Spelling: “Spell rhinoceros”
Maths: “What’s 24 plus 7?” “What’s 8 minus 5?” “What’s 32 divided by 8?” “What’s 43 times 5?”
The Weather: “What’s the weather?”

Try to start questions with ‘who’, ‘what’, or ‘where’. Please be aware that Cayla doesn’t know the time or date.

There are some questions which Cayla will not answer as they’ve been blocked by the safety filters.

Cayla answered a question incorrectly

Cayla looks on the internet for the answers to many questions and she cannot tell if the information is incorrect. She also might have misheard the question.

The app stopped or froze.

Hit the pause/play button on the home page twice and try again. If that doesn’t work try re-starting the app.
