Installed this years ago on a previous phone. Rarely used it as it was quite sparse content-wise, seems to require you to have contacts who already it the app (rather than an open platform like Twitter). Worst of all, after copying everything to a new phone - with the same phone number - it seems to have wiped my account! It's insisting I "sign up", with no login option... I even applied the most recent update to the app...it seems my account is now gone...?!?
