Fixed bugs.

User reviews

It has never worked

Tried it a few times with different updates and it has yet to ever work. Always get an error trying to register.

Probably the best iOS XMPP app

Great XMPP client. The interface might be a little dated, unpolished, and a bit buggy sometimes, but it’s probably the best iOS XMPP app you can find. Hasn’t been updated in a while though. Would like to see some more development on it.

Decent alternative to Monal

Monal has some issues that need fixing but it’s taking forever for the team to do it so I moved to Siskin and it’s pretty decent. Monal used to drain my battery a lot but no such problems with Siskin

Auskunft

Registrierung unmöglich Support finde ich nicht

Cannot activate account and crashes

I tried to register two accounts with sure.im but got no activation e-mails (yes, I checked my spam folder!). I tried logging into those accounts with another client but the response was that the accounts had not been activated.

When I looked at my account settings and touched my account name, the app crashed. I tried again and again but it does this every time with both accounts.

I thought I'd try XMPP having watched a video about how easy it is supposed to be!

I'm on an M1 iPad Pro, if anybody is interested.
