What's Inside
Everything Nobody Explained To You
The parts of the music business that cost independent artists money when they get them wrong.
Short, structured lessons
Royalties, splits, publishing, distribution, marketing, contracts — broken into lessons you can finish in one sitting instead of a 300-page book you never open.
A glossary that explains
A searchable A–Z of the terms that show up in deals and dashboards — mechanical royalties, PROs, ISRC, recoupment — in plain language.
Release checklist
A week-by-week prep list for your next release, with your progress saved as you tick items off. Stop learning about a deadline after it passed.
Search everything at once
One search box across every lesson and every glossary term. Type the word you half-remember and get the answer.
Save for later
Bookmark any lesson. Your saved list lives on your device and is waiting when you come back.
Q&A by topic
The questions independent artists actually ask, answered inside the topic they belong to.
Works offline
Lessons cache to your device, so the app still opens in a studio with no signal, on a plane, or on a tour bus.
Free, and honest about it
The app is free and ad-supported. All we hold is an email address and a password hash so you can sign in — and you can delete that from inside the app whenever you want.

What the app knows about you
Your email address and a password — hashed, never stored in readable form — so you can sign in. That is the entire list of personal information Poseidon collects, and you can delete it from inside the app under Account → Delete account.
Your bookmarks, checklist progress and cached lessons stay on your device and never reach us. We never pass your email address to an advertiser.
The app is free because it shows ads, served by Google AdMob. To do that, Google collects your device's advertising ID and device information — that data goes to Google, not to us. The privacy policy explains exactly what is collected and how to turn off personalised ads.
Want the full masterclass?
The app teaches you how the business works. The Poseidon Music Marketing Masterclass is the deeper, module-by-module course on actually growing a release — with a free tier you can start today.
