If you experience crashes like OutOfMemoryError, try with a lesser number of threads, as your device may not handle this big amount of multiple threads!
This is a Denial of Service Tool for Android !
You just have to enter the IP of the Server OR domain name.
Example: 192.168.2.103, example.com (without http and trailing / !)
Then configure the Power of the Attack (you have to experiment with the values) and press the Start Button!
OFS Stress-Tester uses a hash technology and sends them to the Server, which should struggle handling these requests and collapse.
# For whom is this App?
+ This App is for Server Administrators, who want to test their Server, if they can resist a DoS Attack.
+ This App is for Network Adminstrators, who want to check, if their Network can resist a DoS Attack.
+ This App is for Penetration Testers, who want to test a Server against DoS simply with their Phone.
# For whom is this App NOT?
+ For Scrippt Kiddies, "1337" or Criminals, who have fun with Crashing a Server.
USE WITH CAUTION!
Tested against a Windows 7 Ultimate Machine with 8GB RAM, i5 2nd Generation, 500GB SSD and the CPU Load turned up to 100% after 3 seconds of initiating the Stress-Test.
+ Internet Permission: To Access the Network and initiate the Stress-Test against YOUR Test-Server.
+ Wakelock Permission: To prevent the device from sleep while the Stress-Test runs.
This App is adfree and will always be, also no extra data or anything else will be collected!
It just does, what it should do!
Only for Educational Use, to test your Server, if it can resist a Denial of Service Attack.
It is FORBIDDEN to DoS Servers, which you do not own!
You have to ask the Owner for Permission first!
Im not guilty, if anything happens, you are warned!
The strength of the attack may vary from device to device!
If running against non-local-network targets, the strength varies as well, depending on your network connection!

You can use as a simple benchmark. The higher the number of WU(WorkUnit), indicates that the faster the CPU. Especially if you are equipped with Multicore, so I feel almost twice the value of the measured value =).
Quickly and accurately analyze the severity of stress concentrations in your designs and size your components more accurately before FEA or in-depth analysis. With built-in unit conversions, never worry about the unit scale again.
POST SECONDARY STUDENTS ( Mechanical, Aerospace, Civil Engineering, etc... )
Make your problem sets, labs and design projects a breeze with pre-written formulae which are commonly taught in engineering schools. Improve the quality of your designs by considering stress concentrations at the design stage quickly, and easily.
Simplify your engineering stress concentration calculations with:
- Pre-programmed geometry & loading scenarios
- Reference equations & diagrams
- Integration of sub-equations
- Dynamic calculation
- Built-in unit conversion
- Prominent tabbed output display
- Simplified main screen layout with icons for quick identification
The pre-programmed geometries and loading scenarios allow you to simply select a geometry which matches your own, input your dimensional and force values, instantly see the result and iterate quickly to minimize stress and improve your design.
Either for reference or for double-checking, conveniently view each diagram and equation at the bottom of each calculator's screen in an easy to read graphical layout like you see in reference textbooks.
With the integration of sub-equations, you can benefit from the added ease of determining critical design inputs through additional equations if you have not determined the specific value beforehand.
Dynamic calculation allows you to vary design parameters rapidly and see their result without ever having to re-calculate.
Input your parameters in standard units of measure in engineering without having to do your own conversions.
The prominent tabbed output display makes the answer always directly at hand by displaying the output(s) at the top of the screen. By grouping calculators that can output multiple design parameters in a compact and easy to use "tabbed" display, you can "swipe or tap" left and right on the output field and view all of your results.
The simplified main screen layout contains a easy-to-use list-view of the calculators, each with their own custom icon to make it even easier to identify the calculator you need and reduce the time you spend reading your options.

Clear application cache and dalvik cache to free even more space.
After the integration of new apps, if all is working OK, delete the backup file to free the storage (on newer devices, without the external SD card, the backup will occupy the internal storage space, and there will be the effect that the cleaner has not done its job well)
Root is required!
DON'T INSTALL AND DON'T RATE IF YOU DON'T HAVE A ROOTED DEVICE!!!!
It is highly recommended to make a nandroid backup before changing system files.
In case of errors, please send me the log that will show so i can fix the bugs and errors. Thank you
Updated system applications decreases phone internal memory, because the update is stored in /data/app and the original apk is still in /system/app.
System app cleaner will automatically:
- create a backup of the original apps
- integrate the updates in the ROM
- clear the dalvik-cache and application cache (optional)
By doing this, a considerable amount of internal memory storage will be freed.
How to use it:
- start the application
- let it check for updated apps
- start and let the application finish the work
- restart the device (preferable with deleting the dalvik-cache to free some more space if possible)
NOTE: the first restart will take longer time to rebuild the dalvik-cache(this is normal)
for this is *** ROOT *** required !!

IT IS ONLY TO TEST THE STABILITY OF YOUR PHONE!!!
This app is kinda simple...
It runs a very heavy stress test for your phone/tablet to see its stability.
If your device hangs or reboots or it doesn't respond anymore, that means that is unstable.
To see your CPU USAGE, use an app like URSafe CPU Monitor, because this app doesn't allow you to see cpu usage during the test
It should stop after 2 minutes theorically but it may not work this feature!
THIS APP MAY CAUSE SERIOUS DAMAGES TO YOUR DEVICE, LIKE OVERHEATING AND RANDOM REBOOTS WHILE RUNNING THE TEST!!
I AM NOT RESPONSIBLE OF ANY KIND OF DAMAGE OF YOUR DEVICE!!

If you're just curious of what that means, just go here: http://developer.android.com/reference/packages.html find any class defined here, copy the package name and class name, then paste it into this app. If the class is already installed on your device then it should come up with all of its variables.
An example of how this app can be used is if a Developer creates an app that uses unique features of an Android device that are not available for a particular device; then a user could request that particular app to be available on their device and use this app to assist the Developer in determining if all the needed classes would be supported.
Another example would be the app found here: https://market.android.com/details?id=com.digiwack.k8055Limited only supports Android 3.1 and later. However, a user with a heavily modified Android 2.2 device might be able to install it if they install this app and check for all the classes found in the android.hardware.usb package.
If you found this app at a site other than the Android Marketplace, Digiwack Software does not support any "features" that may have been added after it was scrapped from the Android Marketplace site. You can find the original source of this App here: https://play.google.com/store/apps/developer?id=Digiwack+Software
-Clear App cache
-Clear Partition cache (needs root)
-Clear Dalvik cache (needs root)

What is the App Cache?
Some data that gets saved to the internal memory by the apps you use.
What is the Partition Cache?
An area used by the Android system to cache files.
What is the Dalvik Cache?
Dalvik is the program needed to run apps on your device. This program optimizes each app you use by caching some files on your device.
Especially on devices with less or nearly full internal memory this app can help to boost your devices speed.

In addition it has the ability to mount your system partition as read-write for other applications and clear the Dalvik Cache without the need to go into a recovery menu.
AFTER CLEARING THE DALVIK CACHE YOUR PHONE SHOULD REBOOT.
If it doesn't then reboot manually ...
And tell me what error you got, it should work anyway.
Currently it doesn't pick up default values from the system, and doesn't scale well for some high res devices ... This is on my todo list.
Please let me know if you want anything added !!

Kyoro Stress V2 create Low Memory Killer situation on purpose!!
You think it so simple. just to make application to consume many heap.
but, it difficult that your thinking way.
- A. Android PF restrict application java heap per one process.
- B. heap comsuming application is killed by Android PF.
Kyoro Stress solved this problem.
[KyoroStressV2 's manual]
start consuming heap.
stop consuming heap. and release.
# num of big eater
booting process num.
# eatup java heap size
consuming heap size per one process.
# is retry
# show notification
if true, consume notification.
if true, mean low memory state
boundary low memory state.
if android:largeHeap="true" 's application available heap size.
if android:largeHeap="false" 's application available heap size.
now consuming java heap
now recovery another killed process.
# done all task
all task is end.
this app source is following
Kyoro Text is an application which can display / edit the text of size which is not settled in a heap.
# Kyoro Text can display / edit a big file.
# A screen separation can be carried out infinitely.
* The edit function was added. but, It is not stable yet.
Please do not use it seriously. It is bug-ridden.
* edit function was added. but now developing.
Kyoro Text have many bug about edit text function.
* The test of an edit function is due to finish by the end of this year ..
