Deleting and reinstalling apps on iTouch

[annie108]

I purchased an expensive app, and would like to be able to take it off my iPod when I am not using the app. ( Communicuation device software for AAC)
Is it possible to do this? Can I install and uninstall apps numerous times on the iPod touch using my iTunes account?
Thank you for any help. It was VERY expensive, and I don't want to lose the app.

yes, if you buy an app you can delete it and reinstall it free of charge. i do it all the time

Instead of deleting the app you could stop syncing it. So you don't have to redownload the app afterwards.

Just remove the check mark beside it. Check it again when you want to reload it.

I appreciate all your responses. It helped immensely. I did not want to make a costly mistake with an app.
