Question about FiiO JM21

Good day I am looking for a device for an elderly person. Until now she has been able to use an iPod. I came across this device because she also likes to listen to podcasts. But she can't use Spotify etc. 1 Is it possible to (install) and use podcast apps such as Podcast.de? 2 Is it user-friendly or is the NW-E394 model from Sony, for example, easier to use? https://www.digitec.ch/de/s1/product/sony-nw-e394-8-gb-mp3-player-portable-audiogeraete-5838217
