Not with an iPhone 8 you cannot. You would need a newer device. Apple's current iOS version is 3 major versions newer than iOS 16 and some developers, for various reasons, may stop developing for any but the two or possibly three most recent iOS versions. An iPhone 8 is just going to see fewer and fewer apps being updated for it. You would need at least an iPhone XS to download that app, but I wouldn't buy one of those because you'll likely find that it too will pretty soon drop off the list meeting the requirements for the next app version. I would look at getting an iPhone 11 at the very least.
Incidentally, iOS 17 isn't available at all now. If you had a device capable of upgrading to a higher iOS version it would go to iOS 18 at least.
I am completely unfamiliar with the app your need. I tend to run older equipment myself and sometimes you may find web-based versions available.
