Are story

 

Hello App is a program that started in 2017, when it was called “Mobile Summer”. In its 6th edition it became the “Hello App”. In the last two years, the event that was in person, had to be postponed because of the pandemic. Now we’re back with the idea of ​​a fully online course, which can be taken at any time and adapted to the new reality of our world.
