Interface lang

please add the ability to select a localization in the app. I want to use the English interface instead of my phone's default language

Response from developer

This is possible in the iOS Settings app > Apps > Nautiline, and select "Preferred Language". I will consider adding a setting within the app though.

Great UI, quite a few bugs

Radio Stations - Audio cuts when starting a channel and frequent interruptions makes it harder to enjoy radio added through Navidrome.

Overall stability - Despite multiple reinstallations and even after restarting a new Navidrome instance, Nautiline is experiencing inconsitent streams, with songs becoming impossible to play for a few seconds up to a minute, forcing a few app reboots in order to bring it back. In these instances, quick/full sync does not help.

Also, i can frequently see m4a automatically switch to a lower bitrate AAC format, which is unwanted yet it still happens despite having strong internet connectivity. Same goes for FLAC which sometimes, for some reason, cannot reliably play all the time, with FLAC songs sometimes not wanting to play at all for a few seconds, much like the issue i pointed above.

I still give 3 stars because the dev has replied in a timely manner to my email regarding a certain question i had, which is appreciated.

I also refrain from giving more because the app felt more stable when i first purchased it.

Response from developer

Sorry about those issues, I'd like to hear more about them in an email so I can track down what's changed, since the overall stability of the app shouldn't have gotten worse over time. A few questions: What does it mean for a song to be impossible to play? Nautiline doesn't transcode anything to AAC, so what bitrates are you seeing when streaming m4a vs what you expect? Do all of these issues happen on strong connections? Are you connecting through a VPN, Tailscale, Cloudflare tunnel, or directly?

Great app

Switched from Amperfy to this app and it's honestly way more complete. No bugs and a great UI, that's all I asked for.

Good but…

Overall good and beautiful, but a few features missing:

1. Playlist auto download, so i don’t have to hit download every time i add a music to the list
2. Select multiple songs in all songs, then add them to a playlist, currently I have to move them one by one
3. There is no option to auto download or at least download all favorite tracks
