About this app

EchoLoop is the ultimate loop player and voice recorder for language learners,
musicians, and anyone who learns by listening and repeating.

Set any A-B loop point, slow down the audio, and record yourself alongside —
all in one clean, distraction-free app.

━━━━━━━━━━━━━━━━━━━━━━━━━━
🔁 PRECISION A-B LOOP
━━━━━━━━━━━━━━━━━━━━━━━━━━
Tap A and B to mark any segment of audio or video. The loop plays that section
on repeat until you've nailed every word or phrase. No fumbling with sliders —
just tap, loop, and repeat.

━━━━━━━━━━━━━━━━━━━━━━━━━━
🎙️ RECORD WHILE YOU LISTEN
━━━━━━━━━━━━━━━━━━━━━━━━━━
The built-in recorder lets you speak along with any audio — perfect for
shadowing practice. Playback continues in the background while you record,
so you stay in sync the whole time.

━━━━━━━━━━━━━━━━━━━━━━━━━━
⚡ VARIABLE SPEED PLAYBACK
━━━━━━━━━━━━━━━━━━━━━━━━━━
Play at 0.5×, 0.75×, 1×, 1.25×, 1.5×, or 2× speed without any pitch distortion.
Slow down fast speech to catch every sound, or speed up to challenge yourself.

━━━━━━━━━━━━━━━━━━━━━━━━━━
📝 SUBTITLE SUPPORT
━━━━━━━━━━━━━━━━━━━━━━━━━━
Load external subtitle files (SRT, VTT, SMI, ASS, SSA) or use embedded
subtitle tracks from video files. Subtitles stay in sync even when you change
speed or loop a segment. Fine-tune timing with the sync offset control.

━━━━━━━━━━━━━━━━━━━━━━━━━━
🎵 PLAYS ALMOST ANYTHING
━━━━━━━━━━━━━━━━━━━━━━━━━━
Powered by LibVLC — supports MP3, M4A, AAC, FLAC, WAV, OGG, MP4, MKV, AVI,
and many more formats. Switch between multiple audio tracks in a single file.

━━━━━━━━━━━━━━━━━━━━━━━━━━
📂 SIMPLE LIBRARY MANAGEMENT
━━━━━━━━━━━━━━━━━━━━━━━━━━
Add individual files or entire folders to your playlist. Recordings you make
are saved automatically and appear right in your library. Each file remembers
its own loop points and last playback position.

━━━━━━━━━━━━━━━━━━━━━━━━━━
🔒 COMPLETELY PRIVATE
━━━━━━━━━━━━━━━━━━━━━━━━━━
No accounts. No cloud uploads. No tracking. Everything stays on your device.

━━━━━━━━━━━━━━━━━━━━━━━━━━
PERFECT FOR:
• Language learners practicing listening and shadowing
• Students reviewing lectures or podcasts
• Musicians learning by ear
• Anyone who needs to repeat, slow down, and really absorb audio

━━━━━━━━━━━━━━━━━━━━━━━━━━

Loop it. Record it. Master it
