The application allows you to quickly create short 15-second video notes. In cases where there is no time to take text notes, it is very convenient to quickly open the application and record a short video. Believe me, 15 seconds is enough! In 15 seconds you will have time to say much more than type. The application has the simplest and at the same time very all the necessary functionality. There is nothing superfluous in it and absolutely no connections to the server! Everything happens only on your device! This is the main reason why in this version of the application I have limited the number of possible notes - I don't want to clutter up your device!
And of course, it's completely anonymous! The application does not send any information at all. Only local work!
