About Molly
Molly is a hardened version of Signal for Android that connects to Signal's servers to chat with existing Signal contacts. It is updated every two weeks with Signal features and fixes, with security patches applied as available. Two builds are offered: Molly and Molly-FOSS, the latter without proprietary Google components. Downloads are available from GitHub Releases and the Molly F-Droid repo, with Molly-FOSS also on Accrescent. UnifiedPush requires a MollySocket server and is unavailable for linked devices.
Pricing is not clearly stated.
