Tempo Loop: Video Slow Downer
Music practice: loops & pitch
Free · In‑App Purchases · Designed for iPad
The ultimate practice tool for musicians and music students.
Load any audio or video file and work on the piece like in a professional studio: slow it down to decipher the hard passages, change the key to match your instrument or voice, and loop exactly the bar that resists you — all with professional audio quality and without altering the pitch.
SPEED WITHOUT CHANGING PITCH
• From 25% to 200%, with high-quality native processing
• Perfect for transcribing solos, working up fast passages or ear training
CHANGE THE KEY
• Transpose in semitones (±12) without altering speed
• Fine tuning in cents (±50) for old recordings or non-standard tunings
PRACTICE LOOPS
• Press and hold on the waveform and drag to create a loop instantly
• A/B button to mark the start and end while the music plays
• Loop edges adjust precisely and snap to your markers
UNLIMITED MARKERS
• Mark the intro, the chorus, the solo... and jump between sections with one tap
• Name them and move them with your finger
VIDEO TOO
• Load videos and study watching the performer's hands in full screen
• Tap the screen and the controls disappear so nothing gets in the way
BUILT FOR PRACTICE
• Music keeps playing with the screen locked, with lock screen controls
• Your library and markers are remembered between sessions: every song keeps its speed, key and loops
• Built-in reference piano to check notes instantly
• Open files directly from the iOS Share menu
FREE FOREVER, WITH A 7-DAY FULL TRIAL
Download it free and use ALL the features for 7 days. Afterwards, the player, loops, markers and piano remain free forever; speed and pitch shift unlock with Tempo Loop Pro (monthly or yearly subscription, or one-time lifetime purchase).
Made by musicians, for musicians. If you study an instrument, sing in a choir, play in a band or prepare an audition, Tempo Loop Pro is the tool you will use every day.

Same app, clearer name. Tempo Loop is a video slow downer for musicians: load audio or video, drop the speed without wrecking the pitch, change the key, and loop the bar that keeps beating you. This update refreshes the App Store listing so people can actually find it — the app itself is unchanged. Thanks for practicing with us.
