Transcribe+ combines high quality tempo and pitch-shifting with on-device AI that splits a song into vocals, drums, bass, guitar, piano, and other instruments, so you can isolate and hear EXACTLY what you are transcribing by ear. Now on iPhone, iPad, and Mac! Adjust speed and pitch effortlessly with simple swipe gestures. Tap the waveform to pause the track, then drag to listen at your chosen pace, even one note at a time! Attach chord charts that follow the form of the song, mark song structures or add personal notes using customizable flags on the waveform, and practice specific sections repeatedly by defining looped areas. Key Features: • Speed adjustable from 0.25x to 2x without affecting pitch. • Split tracks into 2, 4, or 6 stems (vocals, drums, bass, guitar, piano, other). • Easy pitch modification by +/-12 semitones. • Fine-tune pitch adjustment slider with 1 cent increments. • Interactive waveform interface for real-time scrubbing and listening note by note. • Chord charts from MusicXML, ABC, iReal Pro, or pasted text. • Beats, bars, tempo, and key detected automatically. • Consolidate and practice loops in a single location with Loop View. • Smart Loops can automatically increase speed or shift pitch with each loop. • Load videos for enhanced visual understanding. • Intuitive 10-band EQ toolbar for refined frequency adjustment and additional isolation possibilities. • Mark and annotate waveforms for efficient review. • Easily export loops or entire tracks in eight formats. • Multiple windows and split-screen multitasking for efficient iPad use. • 11 attractive themes with elegant icons. • Keyboard shortcuts compatible with foot pedals for easier control during practice. • Integration with popular cloud storage services. AI Vocal Removal & Stems Separation: Remove or isolate vocals, drums, bass, guitar, piano, or other instruments on ANY track (without DRM). Use this feature to focus on the instruments you're interested in, or create a play-along track. Stems are split entirely on your device, with no uploading and no limits. If an instrument isn't in the song, its stem is hidden instead of filled with leftover noise. Export any combinations of stems and remix them as you like! Chord Charts: Import common chord chart formats you find online. The chord changes run under the waveform, following the actual form of the song. Transcribe+ listens to the whole song on your device and suggests the exact beat where the form starts. If a bar is stretched or squeezed, or the song is heard at double or half tempo, it offers a one-tap fix. Loop View with "Smart Loops": View all your loops in the loop view. Simply tap the loop icon to start or stop a loop. You can set parameters for a metronome count-in before each loop or auto-increase speed or shift pitch with each repetition. Link loops as you learn, starting with small chunks and joining them together with a tap. EQ ToolBar, Channel Mixer, and Fine Tuning Slider: Further isolate or enhance the part you're listening to with the EQ toolbar or the Stereo Channel mixer. You can also finely adjust the overall pitch of the track in increments of 1 cent. Transcribe+ for Mac: Transcribe+ now runs on the Mac, with a full menu bar, keyboard shortcuts, and all of the same features. Apple Music Support: Transcribe+ integrates with Apple Music, letting you adjust the tempo and add flags and loops to any song in your Apple Music library. Please note, due to DRM music streaming limitations, some features are unavailable on Apple Music tracks. iCloud Sync: All of your flags, loops, chord charts, and settings for each track you load are automatically saved to iCloud. These settings also sync automatically across all your devices. Six stems require a device with 8 GB of memory or more; other devices split 4 stems. Beat detection and chord charts require iOS 27 or macOS 27. Terms of Use: https://dynamicappdesign.com/tos.html

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.

ReceptionRating · Positive reviews · Number of ratings

Slow Down Music | Transcribe+ holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Slow Down Music | Transcribe+ has 5.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 64% of Slow Down Music | Transcribe+'s written reviews are positive against 100% of Loopdrill's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Slow Down Music | Transcribe+ ships an update every 2 weeks, Loopdrill every 5 days. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
