RIP DJ vs iOSamp

RIP DJ is a spectrogram tool for DJs. Drop in any track — MP3, FLAC, WAV, AAC, M4A, OGG, Opus — and RIP DJ analyzes its full spectrum on your device. A live spectrogram and waveform appear while the track plays, and a full-track spectrogram renders once the scan completes. Share the spectrogram image with track metadata to any app. The FFT runs entirely on your phone. No uploads, no accounts, no analytics. Files you analyze never leave the device. The app makes no network requests at all. https://www.ripdj.com/privacy https://www.ripdj.com/terms

iOSamp is a local music player for collectors, audiophiles, and anyone who trusts their own taste over an algorithm. Your files on your device. No subscription necessary, no account creation needed, no ads, ever. Built by a guy who grew up on Hotline servers, oth.net, hoarding FLACs, and caring way too much about ID3 tags.
