ReZu Audio Player

ReZu is an audio player that focuses on simplicity, folders and bookmarking.

What's new in version 2?


Volume reset button and volume menu reset

ReZu warning icon

If the volume is above 40% a red volume icon appears as a reminder (if your screen is larger than 3 inches)

Tapping it will reset the device's media volume back down to 10%

A "reset volume" menu item is always present since the icon bar may need to hide


Continue playing after a phone call ends


ReZu will pause and autobookmark (if enabled) when your phone rings and while you are on a call. A new setting is available in the settings section to enable resume playing after a phone call ends


Default folder tap


ReZu default folder tap

Choose what to do when tapping a previously added folder. For example, resuming from the folder's last bookmark is now an option rather than asking with a dialog

My favourite is to set "Run folders auto bookmark"


Equalizer improvements


ReZu equilizer

New preset equalizer settings may now be available. Items like "pop" or "classical" may appear depending on your device's hardware chipset

Extra base is now an option if your device supports it


Lots of room (show full file name)


ReZu extra room for filename

A new setting to hide all non essential things on the interface to make room for really-long-file-names-that-go-on-and-on-for-detail-dot-extension tracks


Pause from notification


ReZu audio player notifies with pause

You can now pause directly from the system notification. (if your device is android 5 and above)


Bookmark details


ReZu Audio Player

Holding down on a bookmark will now show filename, folder, and position details for system and additional bookmarks


Fade in


ReZu fade in


A gentle fade in was added when the player first starts because I thought it was pleasant


Font size


ReZu can now handle fonts of various sizes gracefully. Setting fonts in your device's "Settings" (not in ReZu's settings) will be applied throughout the application


Plays nicely with others


Various improvements were made to be a good citizen on your device


Speed improvements


A general set of speed optimizations




Core features :


Bookmarking :


ReZu bookmark interface

ReZu can automatically store a resumable bookmark per folder


You can tell ReZu to store as many resumable bookmarks per folder as you like, whenever you like


ReZu can delete resume points, individual or all bookmarks, and forget remembered folders (all stored data)


Bookmarks are shown and separated on a per folder basis. This allows you to leave "Folder a", resume "Folder b's" position, and then go back to "Folder a" to resume "Folder a's" position. It's a unique way to do things. This is best demontrated with "Run folders auto bookmark" setting enabled. You can find this option under the "My folders" button located ReZu's Settings and requires bookmarking behaviour button set to "Keep an automatic bookmark per folder"


If you have ever used Rockbox, you should feel right at home with ReZu's bookmarking features

Choose to purchase, or get the Ad supported free version below



Click/Tap the Google Play image to get the free version



ReZu Audio Player


Why AdSupport?


This is an older full version. Other than the fact that it's an old version, the difference at this time is the splendid icon, the need for internet access, and the advertisements. It's still pretty good though


Since I work on this version in my spare time, it may not contain all of the full versions features listed above. I will try to keep it synchronized with the paid version but no promises






Click/Tap the Google Play image to purchase



ReZu AdSupport


Why buy?


It has all the features listed above.


More space on smaller device's. This version won't hide parts of the interface to make room for the ads (Since there aren't any advertisments in this version)


Privacy. ReZu paid (full) version does not need internet access and has the least number of permissions that I could use without compromising features


Using less resources the full version will give you more battery life


The paid version does not replace the AdSupport version. They will peacefully coexist but blissfully be unaware of each other

Frequently asked questions :

(tap on the question for an answer)


Ok, so I installed it, now what?

ReZu seperates adding a folder and choosing a folder into seperate tasks.
Before you can play stuff, you need to add a folder first. There are 3 little dots on more recent phones in the top right corner that represent a menu. From there you can select "Add a folder". Once you complete that task, you can find the folder you just selected by going back to the three little dot menu in the top right, and selecting "Previous Folders". Click the folder for further options. Some phones however may not have the dot menu, so in this case you should look for a physical button at the bottom of your phone


I tried to add a folder but ReZu says that there doesn't seem to be any folders here and that there doesn't seem to be any playable files here. Now what?

ReZu defaults to your phone's internal storage. Please ensure that your playable files are in your phone's default music folder.
If you want to access your additional memory card or some other folder, select the "Settings" menu option located in the three little dot menu in the top right corner. In ReZu's settings, select the "Default folder path" and wipe out the word "Default"(no quotes), and put a "/" in (no quotes). This will give you access to all unprotected folders available on your device. Now go to the "Add a folder menu" and navigate to your desired folder.
Your memory card is usually in the /sdcard or /storage folder


I want ReZu to delete all resume points and bookmarks and forget all the folders I have selected. How do I do that?

There are 3 little dots on more recent phones in the top right corner that represent a menu. Tap that and then select the "Settings" menu option. Once you are there, select the 3 little dots menu again. From there you can see the "Delete all bookmarks" menu option and the "Delete all folders" options.
Please note that deleting all bookmarks will also delete all resume points as well.


I tap the dots in the top right but the menu I am looking for is missing. What gives?

The "three dot" app menu that your phone usually shows in the top right corner of the application changes based on what you are doing and can be used for navigation. Please check there for relevant options. Tap the "Settings menu" and then tap the "three dot" app menu again for a complete list


My bookmarks and resume points are all gone. I don't think I did anything so what happened?

ReZu needs access to your device's storage to retrieve its data. It seems android blocks access while the device is plugged in to a computer and a file transfer is in progress. Unplug your device from your computer, restart ReZu and everything should return


The equalizer is driving me crazy! Why does the equalizer keep shutting down?

The problem may be in the file. I have had reports that suggest the file playing may contain errors. Try replacing the file with a fresh copy. In the mean time when the track changes, the equalizer will reinitialize. If you want to initialize the equalizer instead of fiddling with the equalizer settings, you can press pause, then play


Why can't ReZu see my file/folder? I know they're there

On newer devices you may need to enable permission to read you storage. You should check your devices "Settings->Apps->ReZu Audio Player" and check that "Permission->Storage" is enabled. If your permissions are enabled or there isn't any permission settings it might be because you have a strange character in the file/folder name that ReZu doesn't like. Try renaming things so it contains only simple names, and/or underscores and/or numbers


Where did all my buttons and stuff go?

ReZu figures out what can fit on the screen and tries to keep the most important interface elements that your screen size supports. Setting your phones font size in your phone settings will also effect what ReZu thinks it can fit on screen. Try reducing your phone font size, or tap the song title to switch Rezu out of "Lots of room" mode. Finally, the AdSupport version contains ads which take up space. So for more space rather than buying a bigger device maybe try buying the full version?
