Store screenshots supplied by the developer.
scylla is a new Hi-Res audio player app featuring “Easy”, “A Lot”, and “Comfortable”.
“Easy”
Already there are a lot of good audio player apps, but they are a little difficult and complex.
scylla was developed with a focus on being simple.
Of course controllable from CarPlay and Apple Watch.
If you want, scylla tells the artist name and title of the now-playing song.
“A Lot"
Additional to your music library, you can import your songs from iCloud Drive, Dropbox, …
Also FLAC *1, DSD *1, and OggVorbis is supported.

scyllaWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
