Why this product exists
The hard part is not finding theory. It is turning theory into reps.
Most players already know scales. The friction is choosing one fast, hearing it over harmony, and staying inside a repeatable loop long enough to improve.
Hear it in key immediately
Move straight into playback with backing tracks and tempo control instead of searching for another loop somewhere else.
Keep the reps honest
Track streaks, minutes, and saved setups so practice compounds instead of resetting every session.
Credibility
Built from a working-musician point of view, not a generic lesson funnel.
The product direction is grounded in real genre practice and serious repetition. That is why the interface stays dark, direct, and focused on playing instead of gamified noise.
Pricing
Free keeps the loop open. Pro removes the ceiling.
Public v1 stays generous enough to prove the workflow. Pro is for players who want the full practice rig every time they open the app.

FAQ
The practical questions.
Who is Improvisr for?⌄
Intermediate musicians who already play, already practice, and want a tighter loop for improvisation. Guitar, bass, piano, saxophone, trumpet, and any other melodic instrument fit the workflow.
What makes it different from charts or YouTube backing tracks?⌄
Improvisr does not stop at reference material. It gives you a key and style, shows what to play, explains why it works, and lets you practice immediately without assembling three tools first.
Does it work offline?⌄
Yes. Public v1 is intentionally local-first. Recommendations, metronome, favorites, and session history stay available without an account.
What is in Pro?⌄
Full backing tracks, wider tempo control, guided routines, and unlimited favorites. Free keeps the core loop available while Pro opens the full practice rig.
