how can I transfer data from my Samsung s5 to my new iphone

Welcome to iMore! What kind of data other than memos?
About the only thing I know to do with memos, is either email them to yourself, or use Box or Dropbox.

If your service provider has an app/service try that... or find a 3rd party cellular sales/repair provider that has a CellBrite machine that provides the service.

It would also be helpful if you describe what desktop platform you are using.

Definitely try the Android to iOS migration tool. My results have been mixed (It worked for my mother-in-law), but Google Drive or Dropbox is a good alternative as well.
