Jamful Looper vs Lofi Engine

Jamful is a looper app for musicians. Record a loop, overdub layers on top. • Each layer draws as a colored ring, filling live as you play • See your whole arrangement as color-coded rings, one per layer • Trim layers for a tighter loop • Everything autosaves to the library • Share a mixdown as an audio file

Lofi Engine generates endless lo-fi music in real time — entirely on your device, no internet required. Every session is unique. No playlists, no downloads, no repeats. The engine composes live piano, beats, and vinyl crackle from scratch, so the music never runs out and never sounds the same twice. Choose from 10 atmospheric scenes — ocean waves, night rain, city lights, server room hum, and more. Each scene pairs a curated ambient texture with generative music produced locally on your iPhone or iPad. FEATURES • Endless generative lo-fi — never the same session twice • 100% offline — works without Wi-Fi or mobile data • 10 ambient scenes with matching visuals • Control mood, key, BPM, and musical scale • Environment mixer: blend rain, thunder, fire, and jungle layers • Auto DJ: let the engine evolve the music on its own • Presets: save and recall your favorite configurations • Sleep timer with smooth fade-out • Background audio playback • No subscription, no ads, no streaming
