Child Silence Timer

Learning time sense and controlling vocal stimming

Child Silence Timer

This app is for parents who want to spend quality, quiet time with their children.
It's a fun way to practice being quiet with your child just by setting the clock-timer.

With this app, voice levels are measured simultaneously by the microphone function of the iPhone/iPad. If the volume of your child's voice exceeds the limit that you pr-set, it will wake up a scary dog and the dog starts barking. But don't worry, soon after the dog, a cute little girl will show up on its screen and cheer your kids up.

Usage example

When your kids are making loud noise at home and/or in public places, scolding them can sometimes cause more problems that it solves. With this app, keeping the sleeping dog from waking up can make quiet time fun for your kids! You can then, instead of scolding, praise the kids for doing well.


✔ You can pre-set the timer from seconds to minutes, or time-free mode.
✔ You can change its voice limit depending on the environment, e.g., outside or in the house.
✔ You can check the history of your challenge in graph form after the end of each session.
✔ The following options are also available.
- Immediate Termination: A session will terminate immediately after the volume of the child's voice exceeds the limit.
- Auto Retry: The next session will automatically restart from the beginning after the immediate termination, and kids can try it until they make it.
- Sounds on/off.

For children with developmental disorders

Children with developmental disorders such as Autism Spectrum Disorder or ADHD can often make repetitive vocal sounds known as Vocal Stimming or repetitive clapping. That can be disruptive in their day lives and may hinder their learning. With this app, children in the spectrum can practice controlling their voices/clapping effectively. This app can also be used as their time-aid because it's easy to check the remaining time of the session visually through the clock-timer.
