How-To: Fix Crashing Apps on Your iPhone and iPad
Nothing is worse than having an app that crashes on you every time you launch it. It can be more frustrating when that app dipped into your wallet before introducing you to the world of app irritation.
To help you use your app(s) without throwing your fancy Apple device across the room, follow the steps below. Be sure to check your app after each solution presented below. If your app starts behaving, you can stop and enjoy. If your app is still going all wonky, continue to the next step until it begins working.
Solution One: The Soft Restart
It sounds like a cliche, but just a simple restart can really solve some of your iPhone/iPad/iPod touch app issues. Those IT folks have been right all along.

Hold down the Lock button
To restart your iDevice hold down the Lock Button at the top of the device until you see the red arrow with the "slide to power off" prompt. Do what it says.
To turn your iDevice back on, just hold down the same Lock Button at the top until you see the fancy Apple logo.
Try your app.
Solution Two: The Hard Restart
If the regular soft restart didn't work, it's time to get hardcore with the hard restart.

Hold down the Lock and Home buttons
Hold down the top Lock Button and the Home button until you see the Apple logo. This will take a few seconds. In the meantime, ignore the "slide to power off" prompt--just keep holding those buttons down until you see the Apple logo.
This method involves a substantially longer restart than the soft restart mentioned in Solution One. We've seen an iPhone take up to 15 minutes to go from the Apple start up logo to being usable. Be patient.
Try your app.
Solution Three: Delete the App and Reinstall From Your Mac
Your app still isn't working? Okay, onward and upward.
Tap and hold on the app icon until it gets all wobbly.
Click on the X to delete the app. You can rate it if you want.
Tap the home button to stop the wobbly apps.
Plug your iDevice into iTunes and make sure the app is checked to be installed on your iPhone/iPad/iPod touch. Sync.
After the sync has finished, unplug your iPhone and soft restart it using Solution One. Some developers recommend restarting the iPhone/iPad/iPod touch after installing an app, and what the heck, it can't hurt.
Try your app.
Solution Four: Install From your iPad/iPhone/iPod touch
Okay, the install from iTunes didn't work. Lets try installing directly to your iPhone/iPad/iPod touch from the App Store.
Delete the app as described in Solution Three.
Launch the App Store app on your iDevice and re-download the offending app. Don't worry if it's a paid app. Apple records of all your purchases and won't charge you a second time to download it (unlike music from the iTunes store).
Give your iDevice a soft restart as shown in Solution One.
Unless the app is fundamentally flawed, or you have a larger issue with your iPhone/iPad/iPod touch, you should be golden.
Solution Five: Restore - The Nuclear Solution
Restoring your iDevice involves removing all of your apps and settings and reinstalling the OS. After that, you have to re-sync all of your stuff. It's not at all difficult, but it's a long process that could take all day if you have a high capacity device. This is definitely the solution if multiple apps refuse to launch and your iPhone is acting insane.

Plug your iPhone/iPad/iPod touch into iTunes. Right click on it in the left hand column and select Back Up.
Allow your iDevice to backup. You're going to need this latest backup to get it back to normal after the restore.

Right click your iDevice again and select Restore from Backup.

Choose the latest backup.
Get ready to have your iDevice unavailable for hours while it puts all your stuff back. Go get lunch, watch a movie, and build a bridge out of toothpicks. Find something to do, because this is going to take awhile.
After it's all over, your iPhone/iPad/iPod touch will be fresh and ready to party. Try the app, and hopefully, enjoy.
And if none of those solutions work and you're still having issues, check with the developer. They may have an update coming that could fix the app. But, chances are, you've already fixed it.

I have a 3G and updated to OS4. All apps worked perfectly for a month then started crashing. It was then I learned about closing apps in memory. This worked for about 3 days then they started crashing again. My company support folks did a restore and a reset which fixed the problem for about a day then the crashing started again. So, they gave me another 3G. I set it up and did not download any apps. I just synched my Exchange and Yahoo mail accounts and calendar. Safari and Email still crash. I downloaded the latest iTunes and Safari and Email only stay open for about 10 minutes then crash.
Since I am experiencing the same problem on with two different phones on the same PC could I be passing a virus down to the iPhone?
Thanks!

I figured out how to fix my iPad apps on this website:

Turns out airplane mode can cause some issues.

I admit I'm a convert from Windows to Apple, and a big fan of the iPhone. But. seriously, this article reflects an uncomfortable reality. Memory leaks are a real issue on the iPhone. I'm running OS 3.1.3 and the problem has gradually increased with each release. I use my iPhone 3G a lot every day. I probably do Web browsing 3 to 4 hours a day, plus am an avid Audible subscriber, listening to 3 to 4 hours of audiobooks and podcasts daily. I usually have to charge both my internal iPhone battery and my InCase Slider external battery daily. And, I find I have to hard boot the iPhone at least once a day - often two or three times - most likely due to memory leaks. Almsot all my apps are major players, and certainly the ones that I use most of the day are - like the iPod audio player, Safari browser, New York Times and Huffington Post. Also, I live in a county in Pennsylvania where there is no 3G service (often not even acceptable Edge). All the surrounding counties are 3G. When I go from my county to one of the others and back, I HAVE to reboot the iPhone, as it seems ATT can't seamlessly hand off the service. I have three months left on my ATT contrasct and can hardly wait until I can switch to Verizon.

I had an 8GB iPhone 3G for the better part of a year before upgrading to the 3GS. During that time I downloaded the System Activity monitor app to off-set the crashing app issue. My16GB 3GS, on the other hand, has had minimal issues with apps crashing. I used to think this was due to the lack of space.
After reading some complaints (which generally rings louder than a compliment) addition to Apple stating they would not be enabling the backgroundng feature in iPhone OS 4 for 3G due to the lack of sufficient memory, I now Have a better understanding about some of the causes. .
This is not to discount the fact that Apple is really good about addressing these issues by releasing software updates and new models.

To download another app such as System Activity Monitor, or FREE Memory -- each of these applications will allow you to "free up memory" by killing all running applications except for background apps such as Mail, Phone, and iPod. Nevertheless, some apps do provide a "Kill All Apps" feature which will include background apps such as Safari, Mail, and iPod. This last option is suggested as [use at your own risk]. Personally, I have used the Kill All Apps on occasion, but don't find it necessary as the basic function is more than sufficient. Furthermore, the above mentioned are iPhone apps, however, they will work on the iPad as well.

Just to verify...When I first received my iPad, I had several apps crash the very first time they ran, but the restart cured the problem in every case.Current 3D work: http://www.mikejamesmedia.com
