I think somebody read your post.

Just got my invite an hour or so ago...Simple has a big section on "what's in the pipeline" for them.

• Android: click the link above and fill out your info through the "device" step. We'll reinvite you as soon as it's ready! • Joint accounts: Sign up with Simple now and add your partner when we're ready! • Mobile check deposit: Coming soon–sign up now and you'll have it as soon as it's ready! • So much more!

Interesting coincidence.
