Best app to find and disable startup apps?

[Grafx]

I have some non system apps which appear to load each time I turn on my phone. What app can show me which ones are loaded and how to disable them at start up?

Task Killers are a very bad idea. Download an app called Watchdog. It will sit silently in the background watching for apps that take up too much of your phones resources, and it will then give you the option of killing the app. If the same app repeatedly causes you an issue, you'll need to report it to the app author (otherwise they can't fix it).

Taken from here:

I develop Android apps so I though I'd explain why a task killer isn't needed on an Android system.

Activities
Android apps use activites to preform tasks. For example, if you use a file manager to send a picture via email, the file manager calls the send activity within an email app, passes the file name to it and the email app sends the picture.. not the file manager. This will result in seeing the email app as "running" even though the user didn't actually launch that email app.

Smaller apps
Using activites helps developers design smaller apps. A file manager app that contains every bit of code needed to do everything a file manager does would likely be so large that no one would want to install it. Developers know that an android phone more than likely has an email app so there is no need for the developer to include email code in his/her file manager to send a picture when he/she can call an activity in an existing email app to do the job. This results in a smaller file manager app since there is no need to include email code or any other code for an activity that can be done via an app that is already present on the phone. This also alleviates redundant code. When you install an app outside of the android market, also known as sideloading, the file manager app calls the package installer (already present in Android) to install the requested app.

Running apps vs. cached apps
The "Manage Applications" list included in many android devices lists running apps as well as cached apps. Cached apps don't use any CPU or battery, they're cached so they will load faster the next time you need them. Killing cached apps results in those apps requiring more time to load the next time they are launched.

System management
By default, every android application runs in its own Linux process. Android starts the process when any of the application

If that still doesn't work ,and your rooted(if not, gingerbreak is pretty easy,just make sure you have a freshly formated to default setting sd card,as it gets picky about that sometimes,and if it doesn't take the first try, try again)you can try App Quarantine. Select what you want to go into Quarantine one app at a time,press the menu key,select lock,and it moves it to Quarantine.I use this for the default browser and launcher.When I boot up the system goes straight to my launcher and when I need a browser it use's mine.I don't get the annoying box that makes me choose. This app should work on everything,just remember to do it one app at a time in case that app move messes up the system,you will know which one to move back.
