Hear what a lesson sounds like
Callee: Why do you think the Moon looks different every night? ... It is the same Moon, but we see a different part of its sunny side. Let me show you on the screen.
An example of a lesson, not a recording of a real call.
What will my child learn?
Pick your child's age to see a few of the skills waiting on the trail. Every child starts where they are, not where their age says.
- Day sky, night sky
- Our planet Earth
- Moon shapes
- Planet or star
- Stargazing
- Spacesuits
- Sun, Moon and Earth
- Rocky planets
- Comets
- Satellites
- Stars and space
- Other moons
- Stars across the night
- Mars missions
- Moon and tides
- Nebulae
- Life of a star
- Scale of the universe
The trail keeps going up to secondary school level, so a child who races ahead never runs out of road.
How a journey works
- 1
It starts where your child is
The trail starts from your child's age, and you can move the starting point. From there every lesson adjusts to what your child actually shows.
- 2
Every call is a planned lesson
Callee picks the next skill on the trail, teaches it by talking, and practices it with questions, games and pictures on the screen.
- 3
Skills light up as they stick
A skill counts as solid only once your child shows it, more than once. Skills that wobble come back for practice later.
What your child sees, and what you see

For your child: a world to explore
Islands and trails on their own map show how far they have come and the next hill to climb.

For you: the whole trail
Every skill marked as solid, needs practice or up next. Tap any skill to see what the lesson covers, call now or book a call for later.
Made for children. Run by you.
No ads, ever
No ads in any lesson, and we never sell your family's data.
You decide when it calls
Pick the days and the time, and Callee rings your child then. You can start a call any time too.
You see every lesson
After each call you see what was practiced and which skills lit up on the trail.
Always the right level
Lessons follow what your child actually shows, so they are never stuck and never bored.

Questions parents ask
What is a journey?
A journey is one subject laid out as an island with a trail of skills, from the first steps to secondary school level. Every lesson call moves your child along it, and Callee plans the next lesson from exactly where they are.
What ages is it for?
Ages 4 to 12. The trail starts from your child's age and you can move the starting point, so a child who is ahead or behind starts in the right place.
Which devices does it work on?
Any phone, tablet or computer: the Callee app on iPhone, iPad and Android, or the website in a browser.
Which languages?
Lessons work in any of our 100+ languages, and a language your child is learning becomes a journey of its own.
What does up to 20 minutes a day mean?
A pass covers journey lesson calls up to 20 minutes a day for each child, as many calls as fit. The time comes back every day.
Can I cancel?
Yes. A monthly pass renews every month and a 3-month pass every 3 months, and you can switch renewal off at any time. Your child keeps calling until the end of the period you paid for.
I have more than one child.
All journeys covers up to 4 children: $89.99 for the first child and $49.00 for each extra child, for 3 months. Every child gets their own trail and their own 20 minutes a day.
Does a pass help me get the robot?
When robot reservations open, every family with an active journey pass gets the invitation 48 hours before the rest of the waitlist.
