### 5/5 — Excellent App since around 2009

*2016-01-16, version 4.7.1*

I have it running on my iPhone 4s & 6 and iPad 1, 2 & 3. Support Team is one of the best of all of the Apps I ever used on both mobile & Mac OSX.

### 4/5 — Does fine

*2014-01-31, version 3.8.2*

Shows what I claims to. iPhone 5 multitasking screen usage is ok too.

### 5/5 — 穩定好用，但不包括釋放記憶體功能

*2010-07-06, version 0*

作為觀察iPhone內CPU負荷/記憶體佔用/常駐程式列表/電量回報的App，可以說是五顆星毫無問題
lite版跟收費版差異在能看到的資訊量，對一般user來說lite已經非常足夠

但是要注意這套「沒有記憶體釋放功能」，去看作者的blog可以發現他對記憶體的研究結論是：他不太建議用普通那種「按一下就清掉記憶體裡常駐App」的作法。

事實上iOS4之後，你可以自己一個一個關掉背景程式，HOME按兩下看清單就好了。

### 4/5 — Thanks !

*2010-02-01, version 0*
