### 1/5 — Can’t make it to work

*2026-01-14*

“No route to host” error. Every other app connects fine

### 5/5 — Всё работает.

*2025-11-14*

В серверном режиме точно работает, в клиенте не проверял.

### 2/5 — Perfekt leider nicht auf AppleTv

*2025-11-03*

Hallo die App ist super einfach zu bedienen und das UI ist perfekt. Auf dem iPhone gibt es die Möglichkeit „Customize Arguments“ wo man dann auch —udp testen kann um Packet loss zu finden. Die Option fehlt leider auf dem Apple TV. Deshalb keine volle Punktzahl. Bitte asap auf Apple TV. Danke

### 1/5 — Не работает

*2025-09-05*

Никуда не коннектится

### 5/5 — Works great

*2025-07-09*

I was suspicious because the last updated is 2 years ago and all the (very old!) negative ratings. But I gave it a try and didn’t nit regret. Works great with iOS 18.5

Also this is the only app I found for iPhone which is able to start iPerf in server mode.

### 1/5 — Halbfertig

*2025-02-03*

Die Idee ist gut, der Programmierer hat aber nach der ersten Integration aufgehört.

### 5/5 — Works well

*2024-11-01*

Works as both server and client!

### 1/5 — For IPhone 15 Iperf tool is not working

*2024-08-06*

Tried the tool with IPhone-15 where not able to run any TCP/ UDP traffic’s.
With Iphone14 this issue is not there.
App need to be updated for compatibility with Iphone15 as well immediately

### 4/5 — tcp -M not work...

*2022-09-24*

何とか対応して頂けるとありがたいです！
任意コマンドが使用出来るのは非常に有能ですね。

### 4/5 — please upgrade to latest iperf

*2022-09-19*

please upgrade to iperf 3.11 and add more option features.
