Developed for kids with their sensory needs in mind, but fun for everyone! Jellio’s Underwater World is an engaging way for kids to learn hand-eye coordination and nonverbal communication skills, while popping bubbles using augmented reality.

- Use free-play mode to decompress while counting your bubble pops
- Practice nonverbal yes/no communication using the thumbs up or thumbs down controls
- Customize your AR experience by enabling or disabling selfie mode, adjusting bubble speed and quantity, or switching to touch screen mode 
- No in-app purchases
- Privacy for kids in mind: Everything is on-device, nothing is stored in the cloud or elsewhere, and we will never record, track, or monitor your camera usage outside of our in-app hand-tracking AR technology.

This app was inspired by and made for those like our team member’s nonverbal son, who loves all things water and is learning to communicate with the world around him. Our mission is to foster independence in anyone that struggles with communication and motor skills in a fun, immersive, and regulating way. We would love your feedback to know if we are meeting the mark for you or your child!
