About this app

Full description

Stop playing flat G-strings. Please.

Note'Em is a music theory utility for people who actually want to practice their instruments and study music instead of being tracked by data-hungry corporations (looking at you “G” and “A”👀). Most music apps want to harvest your digital soul to sell you overpriced sneakers. We just want to stay in your pocket (without sniffing around).

We’ve stripped away the "growth hacks," the "gamification," and the aggressive notification pings. What’s left is a fast, offline, and surprisingly honest set of tools for the modern musician.

WHAT’S INSIDE (OR: THE STUFF YOU ACTUALLY NEED):

AN HONEST TUNER: Our instrument tuner uses your microphone to tell you that you're out of tune and save you from sounding like an apocalyptic siren. It processes audio locally, because we don’t want to hear your butchered version of "Stairway to Heaven" any more than your neighbors do.

A NON-JUDGMENTAL METRONOME: Keep the beat with a standard metronome, or get weird with Polyrhythms and Polymeters. It stays steady even if your rhythm doesn’t.

SCALE & CHORD CALCULATOR: Identify that cluster of notes you just played or find out which scales actually fit that one weird chord.

PROGRESSION ANALYZER: Explore functional harmony without needing a PhD. Tonic, Subdominant, Dominant—it’s all here, color-coded and explained simply.

HARMONIC SERIES EXPLORER: Dive into the physics of sound and discover why some intervals sound like home and others sound like a dental drill.

WHY NOTE’EM IS BETTER (OR AT LEAST DIFFERENT):

NO TRACKING: We don’t know who you are, where you live, or what your favorite tea is. We don’t have a backend, because servers are expensive and we’re lazy.
GLASSMORPHIC DESIGN: It looks premium because we spent way too much time tweaking backdrop blurs instead of practicing our scales.
OFFLINE FIRST: It works in basements, subways, and remote cabins where you go to "find your sound."
ACTUALLY READABLE PRIVACY POLICY: We wrote a privacy policy you might actually enjoy reading. It’s a low bar, but we cleared it.

Note'Em is free, ad-free, and ego-free. If it helps you realize just how out of tune you really are, our work here is done.

Download Note'Em. Stay in tune. Stay isolated from data vultures (but connected to friends).
Finally, a music theory tool that isn’t trying to sell you a subscription.
