I designed Berkanan app to be a general-purpose messaging app that you can use to connect with nearby users, be it your contacts or new friends. I think it's most useful at festivals, airplanes, or in emergency situations when there is no Wi-Fi or cellular connectivity.
The idea isn't something new. The most notable competitor is probably FireChat. However, in my opinion, FireChat is too complicated, is centralized, requires you to register for an account, and, most notably, appears to be abandoned by its developer.
The app is free and contains a non-consumable in-app purchase which allows you to customize your profile, like your name or photo. Don't hesitate to contact me if you want a promo code for this IAP! I have 100 of them.
If you have questions or feedback then share. I'm here and try to answer them. Thanks!
