Press Show Panel button to enable dashboard. You can drag floating window over the screen or double tap to open settings. See video and screen-shots for details.

This application allows you to:
- Easy diagnostic problem processes that consume resources excessively.
- With Cool Tool you can monitor full-screen applications (games, video players, browsers).
- Monitor your Internet traffic without closing the browser window.
- Make your battery level always visible, with accurate percentage scale.
- Monitor how good your CPU governor switches between CPU frequencies in idle/stresses

Tips:
Customize the appearance of the panel using color picker dialogs. Also you can adjust transparency and size of the panel in Sliders section.
Tons of gauges could drain your battery very quickly. Uncheck the features that you do not need. Btw, Cool Tool went to sleep and do not draw anything when your display turns off. It is for power save.

ps: If you want to help me localize app into your native language, let me know.

I realised, that I've been using the free version for a long long time, and have never had any issues with it. So I purchaced the pro version simply to show my support for your work. (probly wont use logging fuction in pro vs free myself) The only issues I have ever had, is getting the current ma value's for charging on a few devices as they hide it all over the place. Unfortunally, they seem to be migrating to cvar valuses instead of text locations, and I havent figuerd out how to pull thoes yet. Keep up the awsome work!

Really like this app. It is helping me to diagnose an issue I have with a different application. Customization to put only the data I want to show and exactly where I want to show it on the screen is amazing. One issue I had is that the app disappeared off the screen while doing my testing of the 2nd application. Any ideas why the app would disappear until I restarted the cool tool app? This is the only time it has done that.

Infinitely configurable, output looks great, performs well without causing major processor or battery drain. Also the only app I know of that can show the activity of all 8 CPU cores with a single gauge.

by D####:

DO NOT BUY! Too many values or readings don't work or are dead wrong, at the least including available RAM and GPS. This app is theft, pure and simple. (Google, get rid of devs and apps like this which are only ripping off customers.)

H70%
by H####:

Really is a cool little app. The customization possibilities are endless. Been using it for years on multiple devices. Oddly it doesn't always run on startup despite "Run On Startup" being selected. Runs on startup maybe 50% of the time. Not a big problem though.

Fantastic app, was just wondering if it was possible to monitor GPU activity with it

Fix permissions like DigiHUD did. On my Note 7 I constantly have to turn off CoolTool while accepting permission changes in other apps. Very frustrating. Back to 5 Stars when fixed. UPDATE: Android 6.0.1 on my Note 4/S7 Edge doesn't do this. Note 7 (Verizon) TouchWiz maybe?

Doesn't keep a log unless the graph overlay is displayed.... as if I want THAT in all my screenshots :( ...also the Pro icon needs to be labelled as such (no way of telling apart)

I really like this app, I first installed it when Google Play Music stated skipping on my brand new LG V10. I was able to track down to culprit and remove the offending app. No performance or battery life issues that I can tell our that I have perceived. My only quibble preventing a five star rating is once I upgraded to Marshmallow the Cool Tools graph stays on top of full screen apps. It's not a big deal for me but will probably (greatly) annoy some people.

Giving this app two stars for an issue that has little to do with it. Screen Overlay warning happens with almost anything that's an overlay. A ROM's own circle appbar will trigger that. It's a tapjacking security feature of your ROM. If it can't be disabled in your settings then you'll have to deal with it. There's nothing to fix in CoolTool.

Great system monitoring tool. One of the best app in google play. I can choose many system properties. Display of each property can be customized in many ways. It is displayed on top in custom place so you can always see it. It is even more amazing on rooted phone. . . . . Unforfunatelly battery current does not work on Android 7 anymore.

I love this application and the awesome control interface is genius. I only found 1 issue that disappointed me and it can be easily fixed. The Battery Total Current status value shows over 4A for a longer than expected duration and is unrealistic value when the CPU has a light load and the clock is less than half. I also tried a simple test adjusting the display brightness to see if Total Current would change but it didn't go up or down

The app started great, then it just starts sucking down battery power.

When exiting full screen mode, the overlay is moved several pixels to the right... having it shown in full screen is the only workaround. The label on the far right always likes to disappear/reappear.

It's a favorite and I finally rated it. Well written app. Very useful. Configurable beyond my wildest expectations.Wish they were all this good. I can see what's going on with my device without diving into menus. A must have for device geeks. I can't imagine not getting the paid version.

5 stars per the free version. decided to buy so can support the dev. just installed it, so far so good, and it picked up my previous settings from the free version. wondering why the internet access is needed for ad banner though (per description) as this version shouldn't have any ads...?
