Every APK here is signed by Vizion Technologies and served from our public GitHub releases, where each version lists its SHA-256 checksum. Sonus is open source, so it is built and released from its own GitHub page, also with a SHA-256 checksum for each version. Because these apps aren't from the Play Store, Android may show a warning before installing. Stuck? Message us on WhatsApp and we'll help.
