### 1/5 — Stopped working

*2026-07-22, version 1.3.2*

Bought this when the twitter/ x hype was there and dev was pushing constant updates, now it’s in a state of abandonment. The dev is probably doing the next big project, but leaving behind a broken app disappoints me and makes me clench my wallet next time I try to get something other than terminus lol.

### 5/5 — 최고!!

*2026-07-10*

원격 SSH연결 후 AI Agent 사용하기에 최고의 앱!!!

### 4/5 — Toller SSH Client

*2026-07-08*

Ein perfekter, schlichter SSH, klein für iOS und iPadOS. Nutze diesen täglich und sehr gerne, es wäre allerdings dennoch noch klasse, wenn es eine Mac Version geben würde. Ich kann zwar die iPad Version auf dem Mac installieren, diese stürzt aber immer ab. Dann gibt es fünf Sterne.

### 3/5 — Really wanted to love this

*2026-07-06, version 1.3.2*

Mosh on my mac pro connect great, but the terminal experience is janky. Love that it was a one time purchase, but needs work.

The bad:

Can’t scroll backwards reliably, pls fix. Terminal ‘judders’ a lot.

Cant reduce font size below 10, which is still a bit too big for me.

The good:

Mosh works reliably, reconnects. SSH is less good, drops within a short time if you leave the app for a short while.

### 4/5 — please support herdr

*2026-06-21, version 1.3.2*

herdr ，switch panes plz support

### 3/5 — Beta at the minute

*2026-06-15, version 1.3.2*

OK, it has Mosh, and no subscription, but you can't even scroll back in the terminal - needs some work

### 3/5 — 会闪退

*2026-06-01*

连接上后会在多次使用cd命令后闪退

### 4/5 — -1 for Tap to Unlock

*2026-05-25, version 1.3.2*

Solid app but unlocking with Face ID shouldn’t require a tap. Really annoying when you have to jump between apps often.

### 5/5 — please add fullscreen mode

*2026-05-17*

please add fullscreen mode

### 1/5 — Most standard algorithms don’t work.

*2026-04-29, version 1.2.7*

Connection Failed
Connection failed: Could not agree on encryption algorithms with the server.
The server may require algorithms not supported by this app.
