Signal beta update adds new features targeted at ex-WhatsAppers

The beta release isn't restricted to cosmetic updates. Also included is a low-data mode for calls and the option to set file destination settings to enable automatic file download, which is another feature directed at the newer audience.

Existing users are also incentivized to invite friends and family with a new feature that makes it easier to send shareable group chat invites.

WhatsApp-converts used to the service's group calling feature will appreciate Signal's enhancement to it. The maximum number of group call participants have now been increased from five to eight in total.

Also, the app now has its first official sticker pack. Signal adds its own power-user twist by allowing desktop app users to create animated stickers, which can then be shared with friends.

Signal's unique proposition is its non-profit nature. Unlike traditional messaging services, whose business model revolves around selling your data to the highest bidder, Signal operates on donations and private funding.

Tesla CEO Elon Musk recently admitted to donating to the Signal Foundation. This doesn't come as a surprise since he tweeted it as an alternative for users upset by WhatsApp's ham-handed approach to privacy.

The recent WhatsApp controversy regarding its privacy policy prompted an exodus of users from the service. This resulted in Signal registering a stupendous 9,483 percent growth following Musk's Twitter endorsement.

The deluge of new users was so severe that the service experienced everything from total outages to encryption hiccups. The beta update replicating WhatsApp features and UI optimizations is indicative of this trend.
