Ever picked up a guitar and put it down because it felt too hard? Crunch fixes that. Crunch is a beginner guitar learning app designed for people who want to actually play - not watch endless tutorials or grind through boring theory. Every lesson is 5 minutes or less. Every session ends with something you can show off. - LEARN THE RIGHT WAY FROM DAY ONE - Start with the Guitar Basics guide - 8 interactive pages covering how to hold your guitar, what every part does, how to read the strings, and how your hands should move. No assumptions. No skipping ahead. - BITE-SIZED LESSONS THAT UNLOCK AS YOU GO - Each lesson is one concept, broken into clear steps. Your first note. Your first power chord. Your first chord change. Your first pentatonic scale run. Every lesson you complete unlocks the next - so there's always a clear next win waiting for you. - BUILT-IN CHROMATIC TUNER - No need for a separate app. Crunch listens through your mic, detects which string you're playing, and shows you exactly how far off you are with a live needle display. Always sound great before you practice. - CHORD LIBRARY - Visual fretboard diagrams for 11 essential chords across three categories β€” power chords, beginner open chords, and intermediate shapes. Tap any chord for full fingering detail and step-by-step placement tips. - XP, LEVELS & STREAKS - Every lesson earns XP. Level up as you practice. Build a daily streak. Unlock 9 badges as you hit milestones β€” from playing your first note to surviving a full week of practice. Progress is saved on your device, no account needed. - WORKS COMPLETELY OFFLINE - No account. No subscription. No internet required. Everything is stored locally on your iPhone. Open the app, play, close it. That's it. - BUILT FOR BEGINNERS - Crunch is designed for people who have never touched a guitar before. No music theory. No sheet music. No jargon. Just a clear, fun path from total beginner to someone who can actually play songs. Pick it up. Plug it in. Crunch.
