Dark21

WHY USE DARK21:
• NO FEES: Dark21 uses your phone's Internet connection (4G/3G/2G/EDGE or Wi-Fi, as available) to let you message and call friends and family, so you don't have to pay for every message or call.* There are no subscription fees to use Dark21.
• SAY ANYTHING – End-to-end encryption (powered by Dark21 Protocol™) keeps your conversations secure. Privacy isn’t an optional mode — it’s just the way that Dark21 works. Every message, every call, every time.
• GO FAST – Messages are delivered quickly and reliably, even on slow networks. Dark21 is optimized to operate in the most constrained environment possible.
• MULTIMEDIA: Send and receive photos, videos, documents, and Voice Messages.
• FEEL FREE – Dark21 is a completely independent. Development is supported by users like you. No advertisements. No trackers. No kidding.
• FREE CALLS: Call your friends and family for free with Dark21 Calling, even if they're in another country.* Dark21 calls use your phone's Internet connection rather than your cellular plan's voice minutes. (Note: Data charges may apply. Contact your provider for details. Also, you can't access 911 and other emergency service numbers through Dark21).
• POWERFUL: You can create group chats with up to 500 members and 25 admins, share large videos, documents of any type (.DOCX, .MP3, .ZIP, etc.). Dark21 is the perfect tool for hosting online communities and coordinating teamwork.
• SAY NO TO USERNAMES AND PINS: Why bother having to remember yet another username or PIN? Dark21 works with your phone number, just like SMS, and integrates seamlessly with your phone's existing address book.
• QUICKLY CONNECT WITH YOUR CONTACTS: Your address book is used to quickly and easily connect you with your contacts who have Dark21 so there's no need to add hard-to-remember usernames.
• WHISPER IN THE SHADOWS – Switch to the dark theme if you refuse to see the light.
• AND MUCH MORE: Share your location, exchange contacts, set custom wallpapers and notification sounds, broadcast messages to multiple contacts at once, and more!
