Brilliant music player


Way better than VOX with Loop and similar services. Pay Dropbox instead and have your own choosing of apps. This app has 24-bit audio support (disabled by default) and very neat library building with online tagging and album covers.
And you can reach your NAS in local network via Samba as well and add files from there to your library and for offline use.
No problem with displaying UTF-8 and UTF-16 chars. So no gibberish and funny looking characters in song names.
Navigating thru your library could have been better organized (say you go under an artist but cannot list albums, just songs) but still the best app among what I have tried (pretty much everything in the App Store) so far.

Excellent MP3 player app

Holland Daly

As a new user to iOS I was becoming very frustrated with Apple’s weak Music app and it’s need to be tethered to iTunes on your desktop if you hope to play your MP3s. I turned to the App Store for another app capable of playing mp3 files and became even more frustrated with the slew of apps that prioritize spamming ads more than anything else. Just as I about gave up I found Flacbox and it’s literally everything I ever wanted the native Music app to be. I can easily download an mp3 from a site and play it in Flacbox or access my library from my Dropbox.

If I could give the Flacbox devs a tip and a big smooch I would. 5/5 bless you Flacbox.

Mega AND ogg support!


If you have music you paid for in a mega account, and it happens to be in ogg format because most everything can play oggs while being open-source, and their not copy protected like mp3s, this app can do it.
In fact I'm having a hard time finding many apps that support mega at all, and strangely, even security conscious open source mega does not play ogg files for some lame reason, even though you can stream other formats of music. So imagine my surprise when I'm just playing around in the app, no music on this new phone to even play yet, and low and behold I see the mega icon under cloud support.

Vlc has cloud support, but no mega. Mega has an audio/video player, but no oggs. This can't be that rare of a situation can it? In fact I see you guys just started supporting oggs recently.

So thanks devs. Open-source (ogg) and security (mega) imo, go hand in hand, maybe I'm just crazy. This is the one perfect app for both. When I finally pay for some apps in a few weeks, this will absolutely be one of them.
