Disclaimer: I do not provide the direct download link if the tool is not developed by me. I only provdie the links where you can download or where the developers posted the download links.

What's this?

So far, I didn't see any place where most essential tools shown in one place. So, I'm trying to show the links for the most useful tools. You may don't need to post the same link everytime to let someone know the place where he/she can download the tools.

I use all apps or tools below except CPU Spy Plus and DS Battery Saver as my daily driver and it's all about my phone... (Of course, I use many other apps for office, photos, browsing, etc. But the below apps are everything for Battery, backup/recovery, system monitoring)

System Tools - Backup, recovery tools, Recovery Kernel, etc....

Mobile ODIN - v3.65 - Chainfire - here

It's been said millions times. "Must Have" app. Use this app to flash Kernel, ROMs, etc. I keep this app always installed in my phone.

SuperSU - v1.25 - Chainfire - here

Enable you to run the system as a super user permission. "Must Have" app. I always keep this app in my phone. I also created flashable zip file for E4GT Stock based rom users - here

CPU Spy Plus - v0.5.54 - realgpp - here

"This is a simple app to display the time the CPU spends in each frequency state. This can be a useful tool in diagnosing battery problems or tweaking your overclock settings. It also displays the current kernel information and some other CPU informations. The app is a massive upgrade of Brandon Valosek's version with a bunch of new features." - Giuseppe Baglio

I use System Tuner Pro and BetterBatteryStats instead of this app but many other users use this app to simply display the CPU usage.

System Tuner Pro - v2.5.10 - 3c - here (free version also available at playstore)

I only use this app to set/change few values - auto kill & startups. CPU usage, lots of tweaks (which I do not use but I use this to check my tweak values are correctly reflected), governor changes, etc. Very useful tool. I turned on this 24x7

Android Tuner - Beta_0.8.10 - 3c - here

This Android Tuner is a combined version of Battery Monitor Widget Pro and System Tuner Pro. This has almost of functions of both two apps but I still see some improvement needed. Not using this app until I see what I want to see - battery consumption graph is not fancy...

Kobridge's Universal Init.d Enabler - Kobridge

This enables you to run the init.d script. Check the previous post for more details and download link.

ROM Toolbox Pro - v5.8.1 - JRummy Apps Inc. - here

Lots of system tools like startup, ad block, CPU control, kernel tweak, buildprop editor, etc. I use this tool mostly to monitor my tweak values, change the DPI, Terminal emulator, etc. Running this 24x7. No direct tweak values changes thru this app.

Odin (PC)

Current version is v3.07. Can be downloaded from Samsung Updates site (check the left bottom side) - here

Triangle Away - here

Titanium Backup - here

Battery Tools - Monitoring, Saving, etc..

BetterBatteryStats- V1.13B3 - chamonix - here

Very useful to check the applications which consumes battery and causing the wakeup alarms, etc. I turned on this 24x7

Battery Monitor Widget Pro - v2.7 - 3c - here (free version also available at playstore)

Useful to calibrate the battery, measure the battery consumption showing it based on multiple graph, I turned on this 24x7

Deep Sleep Battery Saver - v1.9 - Root Uninstaller - here

I do not use this app but Shadow_God is a big fan of this app. It appears that it works great when the screen is off and you can schedule the time to kill the unnecessary apps.

Other Tools - Any other useful tools

XDA Premium - v2.2.1 - xda-developers - here

Very convenient access to XDA Developers forum thru this mobile app. From this Premium version, you can give unlimited "thank you". There are free version also available.

Tapatalk Forum App - v2.4.13 - Quoord Systems Limited - here

Access over 40,000 forums easily thru this single app. XDA is one of those forums. If you have a user of lots of forums, then this would be very convenient tool access multiple forums thru single gateway.

Root Explorer (File Manager) - v2.21.1 - Speed Software - here

You know what this is. To access the system partition, this would be the most convenient (this may not convenient but most successful tool) tool. Very useful to change the permission. If this tool provide the access to ftp or remote host (server), I even don't need ES file explorer. Because of this reason, I'm using both ES File Explorer and Root explorer.

7Zip (PC) - here

Notepad++ (PC) - here

AFV - here

Speed Test - here

AnTuTu Benchmark - here

USB Switcher - here

This tool is very convenient if USB does not show as a mass storage. This tool still works on JB and ICS.
