Support & FAQ

Answers to the most common questions about SoloTracks. If you don't find what you're looking for, get in touch — we read every email.

Getting started

How do I add music to SoloTracks?

There are two ways:

• From your device — tap the + button on the Home screen and pick MP3 or M4A files from the Files app, iCloud Drive, or anywhere else iOS lets you browse.
• Wi-Fi Transfer (Pro) — open Wi-Fi Transfer on the iPhone, then visit the address it shows you in any browser on your Mac or PC. Drag MP3s straight into the browser window. They transfer over your local network — nothing leaves your house.

What audio formats are supported?

SoloTracks plays MP3, M4A (AAC), WAV, AIFF, and FLAC files — the formats iOS itself supports. DRM-protected files (e.g., older iTunes purchases) cannot be played, by design.

Where does my music live?

All imported songs are stored locally inside the SoloTracks app's sandbox on your device. Nothing is uploaded to a server. If you delete the app, the imported files are removed with it — your originals on your computer are untouched.

Wi-Fi Transfer

The Wi-Fi Transfer page won't load on my Mac

• Make sure your iPhone and Mac are on the same Wi-Fi network. Many home networks have a separate "guest" network — both devices need to be on the main one.
• Some networks isolate devices from each other (common in offices, hotels, and cafés). Try a personal hotspot from your iPhone as a workaround.
• Type the address exactly as shown, including the port number (e.g., http://192.168.1.42:8080).

Can I transfer entire folders or playlists?

Yes — drag a folder of MP3s into the browser and they'll all import. Folder structure isn't preserved as playlists, but you can build playlists in the app.

Playback & player

How do I slow a song down or loop a section?

Open any song. Tap the speed button to change playback speed without changing pitch. Tap the flag button to drop A and B markers — the player will loop the region between them. Slowing things down and looping tricky parts are Pro features.

Does it play on the lock screen and Control Center?

Yes — and that's free. Play, pause, skip, and scrub all work from the lock screen and Control Center, with no subscription required.

The app stopped playing when my phone locked

iOS sometimes pauses background audio if a different app grabs audio focus (a phone call, Siri, a video preview). Re-open SoloTracks and tap play — it'll resume from where it left off. If this happens repeatedly, please email us with your iOS version.

SoloTracks Pro

What does Pro include?

• Unlimited library size (the free version is capped at 50 songs).
• Variable speed and A-B loop points.
• Wi-Fi Transfer from your Mac or PC.
• Smart Playlists (Recently Added, Most Played, Liked, Never Played).
• Sleep timer.

Is Pro a subscription?

No. Pro is a one-time purchase. Pay once, yours forever — across every device signed in to your Apple ID.

How do I restore my Pro purchase on a new device?

Open the app, tap the upgrade prompt to bring up the Pro screen, and choose Restore Purchases. As long as you're signed in with the same Apple ID you bought it on, Pro will reactivate.

I bought Pro but the app still shows me locked features

Try Restore Purchases from the Pro screen. If that doesn't work, force-quit and re-open SoloTracks. If it still doesn't unlock, email hello@solotracks.app with the email address tied to your Apple ID and we'll sort it out.

Can I get a refund?

Refunds for App Store purchases are handled by Apple. Visit reportaproblem.apple.com and select the SoloTracks purchase to request one.

Privacy & data

Does SoloTracks track what I listen to?

No. There's no analytics, no tracking, no ads. See our Privacy Policy for the full breakdown.

Will my library sync between devices?

Not currently. Each device keeps its own library. Cross-device sync is something we're considering, but only if it can be done without a server in the middle.

Troubleshooting

A song won't import

• Check the file format — DRM-protected files (older iTunes purchases) won't play.
• Very large files (over ~500 MB) can fail on older devices. Try splitting or re-encoding to a lower bitrate.
• Make sure you have enough free storage on your device.

The app crashed

Force-quit and re-open. If a specific song or action causes a repeat crash, please email us with the steps to reproduce — that's the fastest way to get it fixed.
