I know this request is not related to Usenapp for macOS, but I would love to see this happen!
I currently use NewsTap as my newsreader and NZB for iOS to download binaries on my phone. The latter has not seen an update in years and hence is not optimised for modern iDevices, making it a little clunky to use as it lacks proper integration with the Files app. Using par2 parity files to verify and repair downloads requires yet another separate outdated app by the same author. All features could be consolidated into one app for the sake of usability. An elegant, all-in-one solution like Usenapp for iDevices would be a dream come true!
Will you ever consider this?
