Reco puts a complete set of audio tools in your pocket. Cut songs, trim voice memos, convert formats, merge clips, extract sound from videos and craft custom ringtones — professional audio tools that run entirely on your iPhone, no computer needed. Most audio tools on desktop are overkill for a 20-second cut, and most mobile audio tools want your files on someone's server. Reco is different: every one of its audio tools works 100% offline. No account, no upload, no waiting. Your audio never leaves your device. YOUR COMPLETE AUDIO TOOLBOX • Audio cutter and trimmer with a zoomable waveform • Ringtone maker with ready-to-use M4R files • Voice recorder with live waveform monitoring • Audio converter: M4A, MP3, WAV, AIFF output • Audio extractor: pull the soundtrack out of any video • Audio merger: stitch clips into one seamless track • Fades, volume and speed — sound-shaping tools built in FREE AUDIO TOOLS — YOURS FOREVER • Precision trimmer: cut on the waveform down to a tenth of a second, with pinch-to-zoom, a real time ruler and 0.1s nudge buttons • Keep the highlighted part, or cut a section out of the middle • Fade in, fade out, volume and speed controls — included, not paywalled • Microphone recorder with live scrolling waveform • Ringtone maker: one-tap M4R files plus a simple setup guide • M4A (AAC) export that plays everywhere • Unlimited clips, organized with waveform previews • Every free tool stays free. Forever. PRO AUDIO TOOLS — ONE OPTIONAL SUBSCRIPTION • MP3 export at 128, 192 or 320 kbps — real MP3 files, encoded on your device • Lossless WAV and AIFF export for studio-grade quality • Merge: combine several clips into a single track • Video-to-audio extractor: grab the sound from any video in your library MADE FOR REAL EVERYDAY JOBS • Turn the chorus of a song into your ringtone before your coffee cools • Trim the silence off a voice memo and send just the good part • Convert a WAV recording into a small M4A for chat apps • Pull a quote out of a lecture video as an audio clip • Cut a sample, slow it down, fade it out — and export it as MP3 PRECISION YOU CAN FEEL The editor is built around a waveform you can actually work with: pinch to zoom into a single beat, drag two handles with haptic feedback, scrub the playhead with your finger, and fine-tune each edge by a tenth of a second. Loop your selection until the cut is perfect, then export. PRIVATE BY DESIGN Audio tools should not need your data. Reco asks for no account, collects nothing, and works in airplane mode. The only network feature in the entire app is subscription validation for Pro. HOW IT WORKS 1. Import a song or video, or record something new 2. Drag two handles on the waveform — zoom, nudge, loop until it is right 3. Export in the format you need, or save it as a ringtone Reco Pro is optional: a weekly plan with a 3-day free trial, or a yearly plan. Prices are always shown in the app before you pay. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID settings. Everything in the free tier stays free — the audio tools you start with are yours for good.
