Blub Blub developed the Speech Blubs application to monitor the development and therapy of children’s speech. An increase in children's use of smart devices is, according to some studies, blamed for a 70% jump in the occurrence of speech development problems. One in four children (or 230 million worldwide) needs help with normal speech development and the number of therapists doesn't meet the rising demand.

Speech Blubs is a solution consisting of several self-help applications and a service that connects parents with a speech therapist.
