He's working on an iOS version too. Plus, it's open source so other people can write clients for other operating systems if they want.

26th June: "Just sent first successful surespot encrypted message from iPhone to Android."

It's open source. Fund it and it'll get ported to other platforms =)

I don't see how hemlis is worse though? It's even better since it's funded.

It's worse because:

  1.) It's not open source
  2.) They want to charge for certain features that are free in surespot.
      (on top of the $100k they're already asking for)
  3.) They wont let you run your own server

#1 and #3 does not make it worse. #2 might not either depending on what that feature is.

For an encryption app? I'd almost argue that not being able to access the source code makes it a non starter. There's no way to guarantee a lack of backdoors otherwise.
