Loopdrill vs TuneSlider

Loopdrill is a music practice player for anyone who learns songs by ear. Bring in a track from Files or Apple Music, slow it down without changing the key, mark the passage you are working on, and loop it until it sits under your fingers. Core playback tools are free. There are no ads and no subscription. SLOW DOWN WITHOUT CHANGING THE KEY Play anywhere from 25% to 200% speed while the pitch stays exactly where it was. Slow a solo down to hear every note, then bring it back up step by step. LOOP THE PART YOU ARE PRACTISING Set A and B on the waveform and the section repeats until you stop it. Drag either handle to adjust the range. Long-press a handle or the playhead to move it at one-tenth speed with a magnified view, so a loop can start exactly on the downbeat. SEE THE SONG The full waveform shows the shape of the track. Tap to jump, drag to scrub, and use bookmarks to mark verse, chorus, bridge and solo so you can get back to them instantly. TRANSPOSE IMPORTED FILES Shift the pitch from -12 to +12 semitones to match your tuning, a capo position or a more comfortable vocal range. A 10-band equalizer with presets such as Bass Boost and Vocal helps you bring the part you are copying to the front. APPLE MUSIC AND YOUR OWN FILES Play songs from your Apple Music library, or import MP3, AAC, WAV, AIFF and M4A files from the Files app. Speed control, loops and bookmarks work with both. Pitch shifting and EQ apply to imported files; Apple Music playback does not allow these two controls. IPHONE, IPAD AND MAC On iPad the library and player sit side by side. On Mac you get keyboard shortcuts for play, seek, loop and lyrics, and file import from Finder. One download covers all three, and the Apple Watch companion controls playback from your wrist. LYRICS PRACTICE PRO (OPTIONAL ONE-TIME PURCHASE) Follow timed lyrics, hold to select consecutive lines and loop a passage, and edit timestamps or the sync offset. Import multiple audio files or folders with matching LRC files. Try all Pro tools for 7 days using your own audio and LRC files that you have permission to use. Start the trial explicitly; there is no subscription or automatic payment. Your audio, lyrics and edits remain after expiry. Continue with an optional one-time Pro purchase at the displayed local price, or restore an existing purchase with the same Apple Account. Restoring does not restart the trial. Pro and trial availability depend on your App Store region. Pro includes practice tools, not a lyrics catalog or AI transcription. Who Loopdrill is for - Guitarists, bassists, pianists and drummers copying parts by ear - Singers working on phrasing and timing - Students preparing pieces for lessons and exams - Transcribers who need to hear every detail - Language learners who repeat audio in short sections Privacy: your audio, lyrics and bookmarks stay on your device. Usage statistics are shared only if you opt in.

TuneSlider changes a song's speed without changing its pitch, and its pitch without changing its speed — down to the cent. Built for practicing, transcribing, and slowing down the hard parts. No subscription, no account, no ads. THREE DIALS, ONE JOB EACH Speed, pitch, and fine tune are always independent, and always color-coded the same way everywhere in the app, so you never lose track of which one you're touching. • Speed — 25%–200% of the original tempo in 1% steps. Pure time-stretch: the pitch never drifts, even at half speed. • Pitch — ±6 semitones, a full octave of transposition, in whole-step jumps, without ever touching the tempo. • Fine tune — ±50 cents around whichever semitone you've picked, enough resolution to correct a recording that's just a hair off. BUILT FOR REPEAT PRACTICE Real library features, not just a single-file player. • Per-song memory — speed, pitch, and fine-tune are saved per song and restored automatically the next time you open it, across app relaunches. • Favorites & playlists — heart a song to favorite it, or build named playlists: reorder, rename, and organize the pieces you're actively working on. • Play All & full transport — queue an entire playlist and auto-advance through it, with back / rewind 15s / play-pause / forward 15s / next, on-screen and from the lock screen. • Keeps playing, locked or backgrounded — full lock-screen and Control Center transport controls, and playback survives the screen locking or another app opening. SEE THE MUSIC, NOT JUST HEAR IT Three full-screen visualizers, each driven by the actual live, post-speed/pitch audio, not a canned animation: • Waveform — raw time-domain trace • Spectrum — FFT frequency bars • Pulse — radial burst, by loudness NOTHING TO SIGN IN TO. NOTHING TO SEND ANYWHERE. TuneSlider has no account, no analytics, and no ads. Every song, setting, playlist, and favorite lives only in local storage on your device — the developer never sees any of it.
