LoFi Jazz Generator
Read full descriptionHide full description
Lofi Jazz Generator creates original smooth jazz, on demand. Every track is freshly composed — not streamed, not looped from a library. Just pure, procedurally generated music that breathes like the real thing. Inspired by the intimate warmth of Norah Jones, the soulful groove of Walter Wolfman Washington, and the modal elegance of David Gilmour, every session produces something genuinely new. WHAT MAKES IT DIFFERENT No two plays are identical. The generator composes original melodies, walking bass lines, jazz chord voicings, and brushed drum patterns in real time — drawn from jazz theory, not audio samples. Nine distinct chord progressions keep things harmonically interesting: - Classic ii–V–I and I–vi–ii–V turnarounds - iii–VI–ii–V and IV–iii–vi–V for soul and gospel flavor - A hypnotic Dorian modal vamp - The dark minor ii°–V–i - A bebop-flavored tritone substitution - And more CONTROLS THAT FEEL NATURAL - BPM slider — dial in anything from a slow late-night 60 to a brisk daytime 100 - Density slider — pull the music back to a few sparse, breathing notes, or push it forward into a fuller, busier texture - Mix sliders for Piano, Guitar, Bass, and Drums — shape the sound to your room and your mood - 8, 16, or 32-bar loops SAVE WHAT YOU LOVE When a seed catches your ear, star it. Your favorites are saved locally and ready to replay anytime — perfect for sharing a mood with family or rediscovering a session days later. SEED SYSTEM Every piece of music has a unique seed — a short code that recreates the exact same composition every time. Enter a word, a name, or any text to generate a specific piece, or go fully random and see where it lands. A Half-Eaten Toast creation. What's New: 1.0 - Initial release

Real musical ability lives in your ears — not on a page. Kritus is not music theory, and it is not lessons. It doesn't ask you to read, memorize, or recite. It trains the one thing every musician actually runs on — the ear. You hear a note, a chord, or a phrase, then find it on your instrument by sound alone. NO BACKGROUND NEEDED — AND NO WAY AROUND IT You don't need to read music. You don't need theory, or years behind you. But if you want to truly hear — to play what you imagine, pick out the music you love, and find your way through any song — there is only one path, and your ears have to walk it. Kritus is that path, from your very first note. PUT THE PAGE AWAY No sheet music. No fretboard diagrams. No keyboard maps. Kritus never shows you where to put your fingers, because reading the answer is not the same as hearing it. You listen, you search for it on your instrument, and you play it back — the microphone checks what you played, entirely on your device. WHAT YOU'LL PRACTICE - Single notes, intervals, chords, phrases, and full chord progressions. - Chords that open up: when one is hard to hear, its voices gradually separate so you can catch each on its own, then settle back into a single sound. - The River, which carries you through everything in the order real music actually uses it — practice and review woven together, always moving. - Guitar or piano, with reference sounds recorded from real instruments. A built-in guitar tuner, too. PRIVATE BY DESIGN Microphone audio is analyzed on your device in real time and immediately discarded — never recorded, saved, or uploaded. No accounts, no ads, no analytics.

Verdict
The clearest difference is in-app purchases: LoFi Jazz Generator at none against Kritus's 2. Kritus's advantage is update cadence (fortnightly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
