Does Apple allow apps to be redownloaded for free if you get a new device?

Hi everyone my name is Mike. My wife suffered a stroke and brain aneurysm rupture three months ago. She was paralyzed on left side for awhile and she has improved with physical therapy. The stroke and rupture have left her unable to speak well and she had an emergency trache that damaged a vocal cord. She is still in a rehab care facility. Over the past week speech therapists have recommended that she get an iPod Touch so a communications application known as ProLoQuo2Go can be downloaded onto and she can use that to communication. I have already purchased the iPod and I'm going to download the application sometime within the next day. I heard somewhere that apps can be redownloaded for free if they get lost. Does Apple allow an app that was purchased to be redownloaded for a new iPod? I want to have an alternative planned out in case something happens to the iPod or if we have to replace it in a couple of years. My wife's therapists and doctors aren't too optimistic about her regaining her speech completely. So I'm planning this very carefully

Yes you can. It goes by itunes account, not device.
