The music app for children ages 3 to 5. Two friends, three sound journeys around the world, thirteen instruments. No reading, no ads, no subscription.
One price. Everything included.
It begins this simply
The app opens with two faces. No menus, no letters. Your child taps a friend, and their world opens up.
holds the music
Every song as a big painted picture, three sound journeys around the world, and a mixing deck with two spinning discs.
shows the music
Thirteen instruments like friends, a world of light full of quiet creatures, games with no losing, and a treasure chest for your own recordings.

Take a look inside
Big shapes, warm colours, nothing blinks and nothing rushes. Everything is painted to be touched, and every tap makes sound and light.

Under the hood · The sound
Most kids' apps sound thin and shrill. After the third time you turn it down. Gruvi is built differently: under the hood runs a real sound engine. Every finger tap lands on a note that always fits. And everything runs through the same finishing as a real piece of music, warm and round, never harsh. Your child can play wild, and you still enjoy the sound.
Every tap is musically quantised. Wherever the child taps, it stays music. No frustration, no off note.
Every sound runs through the same chain as a studio master. Full, round, never shrill, never clipped.
Every tone is generated in the app itself, no cheap canned sounds. Warmth like good wooden toys.
The theme song. Forty seconds of Gruvi.
The sound journeys · all three included
Each journey is its own room, and the whole screen is an instrument. Its own songs, its own instruments, its own music player per region. Have a listen.
A big djembe under the evening sky, a kalimba, a jingle ring. Your child plays it all, even shaking rattles. Nine songs from highlife to mbube, to sing along and as karaoke.




Koto strings to pluck, a singing bowl that swells under your finger, a taiko by the shore. Here even silence is part of the music. Ten songs from guzheng to singing bowl.
Fairy lights over the evening square, clave and tumba as stepping stones, a güiro that rasps under your finger. And the device itself is the shaker: shake it to make the groove. Ten songs from samba to salsa.


All three journeys are included in Gruvi. No extra purchase, no subscription.
When the day grows quiet
Gruvi knows the time of day. In the evening a quiet, warm light settles over the whole app, and in the world of light four still picture-book worlds wait, full of creatures that glow to the music. Made for the hour before sleep.

Made with love
71 song motifs, drawn by hand, warm and muted like a good picture book. Your child recognises their songs by the picture, long before they can read.
Also for streaming
In the car, at bedtime, on the go without a screen. The music from Gruvi lives outside the app too. Have a listen where you listen anyway.
Honest and one-time
pay once, never again
Less than a picture book. And it makes music when you shake it.
