Serious App - Can be the best out there!

I just started looking into HiDef Audio and started my collection. One of the key piece is to have a portable way of playing songs and this app is hands down one of the best.
However just a few things to improve there:
- UX/UI could be better (it’s a bit of a mess - I can tell I am a pro software PM/architect/UX/UI designer working for $$$ corporate apps), even if I am not a big skeuomorphic proponent I would love an interface that mimics classic audio equipments (the way the volume buttons are implemented by ex.), you can get the inspiration form the amazing you tuber channel Techmoan (I love that guy!)
- I have my HD files stored on iCloud (or other cloud service through the Files app), please find a way to use those instead of copying everything on the SSD
- For those of us who are using external DAC, please indicate what is the type/rate of the connection (I’d like to make sure I am using DSD all through)

PS: I can help you with those if you’d like...

The Best! The updates keep coming!

I love that they keep this app updated, adding things, working out bugs.. Last update fixed that sound cut off bug every time the shuffle button was pressed while playing music. The sound would abruptly cut off then back on, just a second but really noticable.

However there's something wrong with the player window that's viewed when the phone is locked. I'm not sure if it's the app or iOS but, the mini player that's used when locked doesn't update nor is it responsive. It'll show the name of a song I played days ago and it stays that way. The buttons do not respond, the only way it works again is if I reset the phone. I hope you guys can replicate this bug on your end, let us know if it's iOS. Thank You for this amazing app!

Awesome app

This app is awesome but you should exclusively work with Apple Music to make it where all settings such as equalizer can be used. Maybe charge a little more for the app at purchase. Apple and iTunes don’t have an adjustable equalizer. Presets are not as good as being able to adjust it yourself. Just whatever you do don’t do a subscription. Most people who use your app won’t want that. Paying a monthly fee to use features in an app makes no sense and not everyone can afford monthly.
