### 5/5 — landscape mode request, please and thank you~!

*2024-01-01, version 2.0*

I'm absolutely thrilled to give it a sparkling 5-star rating! I'm head over heels for how fabulous the analyzer's display looks and everything else. But, oh dear, on the iPad, there's no landscape mode, and it would be beyond amazing if that could be added so I don't have to keep switching to portrait to enjoy everything!

### 1/5 — Simply doesn’t work

*2024-03-19, version 2.0*

I tried doing a DNS look up multiple times and my screen goes blank. When I hit the start button I tried to do a land scan on my Wi-Fi and it flickered every time I hit the start button just ain’t working for me.

### 2/5 — You cannot find one single word about what you get on the pro version

*2024-01-21, version 2.0*

I dont get it. 
Its a nice free app and i use it to free some space on my ipad Ram. But it never stay for long , i tried to get some info of where all my Ram is working but you cannot get much info but title on where it used. 
I thought maybe the Pro version will give me some more info or option to fix things , but nothing , not on the app any not on the app store download page 
Shame

### 5/5 — 素晴らしいアプリをありがとう

*2026-03-16, version 26.0*

日本人ユーザーです。たくさん試した中で個人的に1番使いやすかったシステムリソース情報アプリです。広告の量は少なく、UIはモダンで分かりやすいです。開発者の方が日本語を読めるかは分かりませんが、いいアプリをありがとうございます！

追記 便利すぎてProも買いました。

### 5/5 — Tech level tools

*2026-02-26, version 26.0*

Retired call center Telecom Engineer; these tools provide deep insight to what is actually going on on inside your device…yes I would recommend to any tech wanna bee!  >tc-syr

### 5/5 — Crystal Clear

*2026-02-10, version 26.0*

Love the insight into the operation of my phone. It’s good to know what my processor is struggling with and what’s eating up my RAM. I wish I could use it as an overlay in my apps to see in real time what’s happening. Like PIP window in the corner. But honestly this is a great app. It gives me insight to how my phone is running.

### 5/5 — Try it out!!!

*2026-02-03, version 26.0*

If highly recommend this app for anyone looking to monitor different starts on your phone. It’s an excellent app in design and features imho.
