### 1/5 — It has never worked

*2026-06-08, version 7.4.0*

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

### 5/5 — Probably the best iOS XMPP app

*2026-01-18, version 7.3.3*

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.

### 5/5 — Decent alternative to Monal

*2025-11-25, version 7.3.3*

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

### 1/5 — Auskunft

*2025-08-10, version 7.3.3*

Registrierung unmöglich Support finde ich nicht

### 1/5 — Cannot activate account and crashes

*2025-05-05, version 7.3.3*

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.

### 5/5 — GREAT xmpp messenger!

*2025-04-06, version 7.3.3*

The styling is impressive and they have both dark and light mode automatically. They have easy user friendly (considering you’re into this stuff it’s user friendly) interface that is helpful if you’re stuck. They even have an in app way to join their support server.

I would REALKY recommend this app since it’s really great and supports almost all you need with xmpp. Once you get the hang and feel of it it’s a great tool.

P.S. they also have push notifications which is crazy helpful.

### 3/5 — Notifications + Audios don’t work

*2025-02-17, version 7.3.3*

The app is blasting me with notifications which makes it unusable for now

There’s also a problem with the audio sending, the buttons to stop or send the recording don’t work on my iPhone, I can’t close the recording UI and I have to restart the app. 

That’s too bad cause I prefer your UI than monal, but thanks anyway for your work ❤️ Free software will free us all

### 1/5 — crashes during sign up to tigase.im

*2025-01-22*

crashes during sign up to tigase.im.
Don't waste my time. Good bye.

### 3/5 — Chatverlauf kann nicht gelöscht werden

*2025-01-09, version 7.3.3*

Eigentlich ein super IM Client. Leider kann man den Chatverlauf nicht löschen. Sogar nach löschen und wieder installieren der App ist der Verlauf wieder da. Damit ist die App für mich nicht benutzbar. Sehr schade! Bitte korrigieren!

### 5/5 — good but some features not there

*2024-11-10, version 7.3.3*

good software for foss instant and secure messanging

in this version i cant send screenshots directly from iphone, only gallery
it says not supported from xmpp server
