### 4/5 — Useful but could use some enhancements

*2026-08-15*

This app is great for troubleshooting http issues from your phone. It even follows redirects! It could implement more options found in the curl cli, but it’s a solid 4/5 app!

### 5/5 — Perfekt!

*2025-12-15, version 1.17*

Just works. No ads. Gamchanger!

### 5/5 — Super

*2025-09-17, version 1.17*

Einfach perfekt um schnell Informationen von Extern über das Ausliefern der Zertifikate zu haben. Danke.

### 5/5 — Weltklasse!

*2025-02-19, version 1.17*

Das ist ein Tool welches ich so auch auf dem Desktop haben möchte! PERFEKT! DANKE!

### 4/5 — Missing search and font setting

*2024-12-17, version 1.17*

Otherwise it’s great.

### 4/5 — Way better than the other ones.

*2024-09-04*

This is way better than the other ones. The only issue is it chokes on any download that is greater than 200k which is pretty common nowadays.

### 5/5 — iPhoneでcurlとか便利すぎ！

*2024-06-11, version 1.17*

細かいオプションもあるし、ちゃんと動きます！

### 5/5 — Clean and Productive.

*2024-02-07, version 1.17*

Second all of the points from @Banjor_ 8/13 review.

Very usefull and clean interface.

Thanks for making this Jason Cox!

### 5/5 — Thorough and Complete HTTP transaction logs

*2023-08-14, version 1.17*

What I hate about most HTTP transaction parsers is that they try to sweep under the rug a lot of what is going on behind the scenes. Jasosn's iCurl is great because it logs everything, so even though it can be a bit slow when parsing a whole lot of data (look at what a simple HTTP GET against Google.com gets you for various user agents for instance) you get to see all of that. This is enormously helpful when trying to do low-level network troubleshooting at the layer just above packet capture. When combining the log from iCurl with a PCAP packet capture, it helps to show exactly what is being loaded across the network which is a big part of the answer "why is it taking so long?" when diagnosing a slow connection. This is especially important for API and troubleshooting scenarios, I consider this tool a hidden gem that I utilize when investigating network shenanigans. I use this on my MacBook Pro with Apple Silicon in addition to my iPhone and iPads, I love that it works on all platforms. A great app, so much value and I'm so glad that Jason Cox decided to make it available. Thanks!

### 5/5 — Works well!

*2022-08-21, version 1.17*

Works as intended
