#SimpleX came close, however it was let down by several factors (some may have changed since):
- is funded by Jack Dorsey of Twitter (big red flag),
- issues with group messages arriving out of order or not at all, and getting de-sync'd
- is written in Haskell so harder to contribute or write bots for
- is a memory hog on both mobile and desktop
- poor UX including onboarding (private routing? incognito mode?)
- poor multi-device support (must have mobile app running to use desktop)
