Vocly

Vocly is an Android app that separates audio and video on a phone into vocals and instrumental tracks using on-device AI. Standard mode separates vocals from instrumental, while Advanced mode can also identify drums, bass and other sounds. It accepts MP3, M4A, WAV, FLAC and OGG audio. In the mixer, users can mute, solo and balance stems, loop sections, adjust tempo from 75–125%, shift pitch by ±6 semitones and compare with the original. Users can add and sync their own lyrics for karaoke. Vocly can export an imported MP4 or MOV with only vocals or music while retaining the picture; audio exports include M4A, WAV and FLAC, with options for separate stems or a custom mix. Separations are saved locally, and a batch queue supports multiple files. After a one-time model download, the app works offline. The free plan costs nothing and includes ads. The developer says media, lyrics and exports are not transmitted, though the free tier uses Google AdMob, which may collect advertising ID, device information and ad interaction data.

Vocly offers stem separation, mixing and karaoke tools, with processing available offline after its initial model download.

Vocly may suit singers, music students, teachers, choirs, band members and creators who want to separate or remix audio on Android. Its karaoke and video export tools may also fit people making karaoke tracks or editing videos.

Vocly is an Android stem-separation and practice app for singers, music learners, worship teams and creators who want to work with audio on a phone. It is especially suited to people who value local processing, karaoke preparation and flexible mixing more than a desktop workstation. Its free tier is unusually capable, while the paid tiers matter if you need video export, higher-quality processing or unrestricted use.

Overview

Vocly turns audio and video files into usable stems on the device. Standard mode separates vocals from instrumental backing; advanced mode further divides vocals, drums, bass and other parts. That range serves both a quick backing-track job and more focused rehearsal or remix work.

After a one-time model download, processing runs offline. Projects are saved locally so they can be reopened and remixed, and a batch queue handles multiple files. The privacy policy says audio, video, lyrics and exports are not uploaded or transmitted. No account is required, and the app has no analytics or crash-reporting SDKs. The free tier does include Google AdMob, which may collect advertising ID, device information and ad-interaction data; Google Play Billing handles purchases, with the developer receiving entitlement status rather than payment details.

Key features

Separation and mixing

Audio separation supports MP3, M4A, WAV, FLAC and OGG. The mixer can mute, solo and balance stems, loop sections, change tempo from 75–125%, shift pitch by plus or minus six semitones, and A/B compare the result with the original. These controls are practical for learning a song, finding a comfortable singing key or checking an arrangement, rather than merely generating isolated tracks.

Karaoke and video

You can paste and synchronize your own lyrics and play them with the instrumental, making Vocly useful for rehearsal and karaoke-track creation. Imported MP4 or MOV files can be exported with only vocals or only music while retaining the original picture. That is a meaningful advantage for video editors and creators, although video export is reserved for Pro.

Exports and workflow

Exports are available as M4A, WAV or FLAC, with choices for vocals, instrumental, separate files or a custom mix. Local project storage and batch processing reduce repetitive setup when working through a set list or a folder of source files.

Pricing

Free

The Free plan costs nothing and is supported by ads. It includes separation, the mixer, karaoke mode and the stem library, with no account or sign-up. It is the sensible starting point for occasional practice and for deciding whether phone-based separation fits your workflow.

Pro monthly

Pro monthly has custom pricing and is billed as a monthly Google Play subscription. It removes ads, adds the HQ model, all export formats, video export and unlimited separations. Choose it if you regularly process files or need the video and higher-quality options without making a permanent purchase.

Pro lifetime

Pro lifetime also has custom pricing and is a one-time lifetime Google Play purchase. It carries the same ad-free, HQ, export, video and unlimited-separation benefits as monthly Pro, making it the better fit for sustained use when the upfront cost suits you.

Platforms

Vocly is available on Android. Its on-device model and offline operation are useful on a phone, but there is no desktop or iOS version for users who need cross-platform projects.

Who it's for

Singers, worship teams, choirs, music students and teachers can use the stem controls, looping, pitch shifting and lyric sync for focused practice. Band members, cover artists and producers gain separate parts and custom mixes, while YouTubers, podcasters and video editors benefit from preserving the picture during vocal-only or music-only video export. It is less suitable for teams that require shared cloud projects or non-Android access.

Pros and cons

Pros

• Strong free feature set: separation, mixing, karaoke and a local library are included without an account.
• Private offline workflow: processing and saved projects stay on the phone after the model download.
• Useful practice controls: tempo, pitch, looping and A/B comparison support real rehearsal needs.
• Flexible output: M4A, WAV and FLAC exports include stems or a custom mix.
• Video preservation: Pro can export vocal-only or music-only MP4/MOV files without removing the original image.

Cons

• Android only: iPhone and desktop users cannot use the app.
• Ads on Free: the no-cost tier includes AdMob data collection related to advertising.
• Key capabilities are paywalled: HQ processing, unlimited separations and video export require Pro.
• No shared account workflow: projects are local, which limits collaboration across devices.

Alternatives

See our AI Voice Isolators list for more options. Pick AudioShake if you need Android plus broad desktop, web, API or self-hosted coverage, a free 200-credit starting allowance and files up to 10 minutes. LALAL.AI suits users who want a cross-platform service with a free relaxed queue and preview results, though its starter tier limits uploads and full downloads.

Choose Denoise for focused noise reduction on Android or iOS rather than full stem work. clir Focus and clir Hearing are iOS alternatives for their respective hearing-focused use cases. Krisp Voice Isolation is the better direction for enterprise or server-side batch processing. Music Separator offers Android and iOS access with unlimited vocal separations on its weekly plan. AIVoiceSeparator is a web/API choice with three free songs per month and studio-quality export options.

Verdict

Vocly is a strong choice for Android users who want private, offline stem separation plus serious rehearsal and karaoke controls in one app. Its free plan covers the core workflow, and Pro adds the features that make it viable for frequent processing and video work. Look elsewhere if you need iOS, desktop collaboration or a cloud-based multi-device setup.
