Spinlane: DJ Mixer & AI Stems

Spinlane is a DJ app and music mixer for Android, built so the music answers your hands the moment you touch it. Mix your own music files on two decks, pull a track apart into vocals, drums, bass and the rest with AI stems, learn to DJ step by step, or let the party automix run the room. One payment unlocks Pro. No subscription, and never an ad while your music is playing.

MIX ON REAL DECKS
• Two decks with crossfader, 3-band EQ and filter on every channel
• BPM and musical key detected for every track, with one-tap sync
• Hot cues and auto loops that land on the beat
• Six core effects free, every effect in Pro
• A low-latency audio engine designed for ordinary phones, not only flagships
• Headphone and Bluetooth guidance: Spinlane tells you when a wireless connection adds delay

AI STEMS: VOCALS, DRUMS, BASS, OTHER
• Separate any track from your library into four stems
• Vocal remover: mute the vocal for an instant instrumental, or keep only the vocal for an a cappella
• Drop the drums out for a breakdown, bring them back on the one, and remix live
• Stems are saved on your phone, so they play offline afterwards
• Free: 3 tracks a week, plus extra tracks by watching an optional rewarded ad
• Pro: about 300 tracks a month under a fair-use limit

LEARN TO DJ
• Short, hands-on lessons, from your first fade to your first full mix
• Beatmatch trainer: match tempo and phase by ear, with a live score
• Practice phrasing, EQ blends and clean transitions at your own pace
• The first five lessons and the beatmatch trainer are free

PARTY AUTOMIX
• Pick a playlist and Spinlane mixes it for you, beat-matched, with smooth transitions
• Take over at any moment, then hand it back
• Pro adds advanced transitions that use stems, such as a vocal handover between songs

RECORD YOUR MIX
• Record what you play and share it anywhere
• Free: mixes up to 10 minutes. Pro: unlimited length in lossless WAV

AN HONEST FREE TIER
The free version is a complete DJ app, not a trial. It shows a silent banner and, only after you save a recording, an occasional full-screen ad. There is never an ad during playback, and no ad ever makes a sound over your mix.

PRIVACY
Your music stays on your phone. When you ask for AI stems, that one track is uploaded to our own servers, separated, and deleted after processing; the stems are sent back to your phone and expire on our side. No account needed. Ads are served by Google AdMob with your consent choices respected.
