## What is Jazz Improv Practice & Scales?

Blank-page paralysis kills more practice sessions than a lack of talent. You sit down, pick the same key you always pick, noodle the same licks, and call it a day. Jazz Improv Practice & Scales fixes that with one tap: it deals you a complete improv prompt — key, scale, tempo, mood and duration — so the decision is made and the only thing left to do is play.

Most practice apps hand you a metronome and a chord chart and leave the hard part to you. This app is built around the prompt. Five cards, each one a real musical constraint. Lock the ones you want to keep, reshuffle the rest, and every session lands somewhere you would never have chosen on your own.

WHAT YOU GET
• Sit down and start playing within seconds — no more deciding what to practise
• Stop hiding in C Major: 12 keys × 12 scales dealt at random, biased toward your instrument
• Grow one variable at a time — hold your favourite key and let the scale, tempo or mood change
• See the exact notes of any scale in any key, with intervals and a plain-English character sketch
• Set the groove before the first note with a visual, haptic and click metronome at the dealt tempo
• Keep the prompts that sparked something, add a note about what worked, and find them again by search

PERFECT FOR
• Guitarists and pianists who want to escape the two scales they always fall back on
• Horn and string players building fluency across every key before the next gig
• Jazz students working through modes, harmonic minor, whole-tone and diminished
• Bands and duos who need a shared constraint to jam over in rehearsal

WHY NOT JUST PICK A KEY YOURSELF?
Because you will pick the comfortable one. A dice roll has no habits. The app pairs a random draw with per-card locks, a tempo feel label from Ballad to Burning, and a session history you can rewind — structure that a coin flip or a scrap of paper will never give you.

PRIVATE BY DEFAULT
The app works fully offline. There is no account, no sign-in, no ads and no tracking. Your saved prompts and notes live on your device and nowhere else.

FULL ACCESS
The app requires a subscription or a one-time purchase. Choose a weekly plan, a yearly plan or a lifetime purchase to unlock unlimited prompts, per-card locking, the complete 12-scale library, the metronome and unlimited saved prompts. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your App Store account settings.
