For HighLoad++ Serbia we have mobile app.

Q: Why do I need this app?
A: The app partially duplicates the website: it has a schedule, a description of the talks and speakers, a list of partners, the F.A.Q. But there are things that are not on the website: general chat, social networking, reminder notifications for the talks you selected. There's also our support on the app.
The important thing is that the app displays the schedule even without an Internet connection

Q: Where can I download the app? What is it’s name?
A: The app name is Event.Rocks and it is available on the AppStore and PlayMarket. Here are the link to download it: admin.eventicious.com/eventrocks.

If you didn't enter your e-mail address during registration, if you don't have a personal account on ontico.pro, or if you can't find your pin code, please contact our support via Telegram @HighLoadIntSupport or e-mail support@ontico.pro.

Q: Can I communicate with speakers via the app?
