Cons
Con Last update was 2021
Con Buggy
There are little annoyances here and there, from dark theme problems making text unreadable to crashing and missing notifications.
Con Lacks features compared to other offerings
Con No web interface (yet)
Currently there is no web interface to send message using your computer. Project leads have teased screen shots of the web interface.
Con Few users currently
Allo was just released in September, 2016 and it doesn't have a very large following yet. We haven't yet seen how popular it's going to be.
Con Exclusive
If your contacts aren't on Allo it is worthless, and no one is on Allo. Tried it after Hangouts fail, discarded it within days.
Con History deletes on sign in
If you uninstall the app or migrate to a new phone your messages history is deleted. This, despite the fact that Google keeps a copy of your messages permanently for data crunching.
Con Single device
Part of reliably saying if one saw your message, and having it tied to a phone number, is that you cannot have the same Allo account on two phones.
