Every folder.
Your Music app.
One library.
Your music lives in a dozen different places. Rondio treats all of them as one library — the tracks you ripped from CDs, the tracks you bought, all playable in one go.

Leave your files exactly where they are.
You don't have to consolidate anything. Point Rondio at the places you already use, and it spans all of them as a single library.
Register up to 10 folders
On-device or cloud storage — if the Files app can see it, Rondio can register it. Pick one parent folder and everything beneath it comes along.
Reads your originals — never copies them
No second copy inside the app, so your storage doesn't double. Move or rename files later and your play counts and favorites follow them.
Your Music app sits on the same shelf
Tracks in the Music app line up as just another source. Ripped from a CD or bought outright, they play side by side.
Setup is: choose a folder.
Choose where your music lives
Pick a folder through the Files app. Folders on your device and cloud storage show up in the same picker.
No waiting around
Tracks are read in the background and appear in the list as they land. You don't have to watch a progress bar.
Add more whenever
New storage location? Add it later. Up to ten in total — the Music app counts as one of them.
High-precision Rondio Shuffle
When you tap shuffle, Rondio lays out the order for every track in the range first. Not just a mix: it spaces the same artist apart, pulls rarely played tracks forward, and spreads your favorites evenly before playback starts.
Lower play counts get weighted forward — as a tilt, not a strict queue order.
After the order is set, same-artist tracks are spaced apart — as are duplicate titles from different albums.
Favorites are spread evenly through the round — not front-loaded, just never far away.
Shuffle the album order and keep each album's own track order intact.
60 songs never played
60 songs never played
60 songs, 60 plays. Both sides play the same number of times — only the order differs.

Frequently asked questions
What about tracks kept in cloud storage?
They work once downloaded to the device. When you register a folder, Rondio asks whether to download the tracks that aren't on the device yet, and shows roughly how much space that takes. Tracks you skip aren't listed.
Does registering a folder double my storage use?
No. Rondio doesn't copy anything — it reads your files where they already are.
Does it stop working after 14 days?
No. It keeps working as a free player. Playable folders are limited to one, and shuffle becomes basic. Nothing you registered is deleted.
Can a registered folder stop working?
If the location disappears or access expires, that folder is flagged as needing to be re-selected. Pick it again in Settings and it's back.
Can I play tracks streamed from Apple Music?
No. Rondio plays files you own — ripped from CDs or purchased. Subscription-streamed tracks are protected and can't be handled.
Bring every track together.
Every track you already own, every place you keep them — one library. Start free.
