You can clap with your one finger on the screen.
Interval and loudness are able to be changed by the location on the screen.
When you use gloves or your hands are not free, you can use this app instead of your hands.
This is free version, so clapping time is limited for 5 seconds.
Clap Helper is no limitation and no Ad.
