Good questions, answered plainly.

An audio-first learning app. You pick a path — a short, ordered sequence of lessons on a single topic — and listen on your own schedule. The catalogue is curated and written to be heard, not scraped book summaries or a podcast back-catalogue.

Podcasts ramble, audiobooks are long, and online courses mostly go unfinished. A Catalyst path is sequenced day by day, written specifically for listening, and short enough that finishing it is normal — not heroic.

Most lessons run about ten to twenty minutes. You decide when, and how many — there's no schedule the app invented for you. Pick it up on the train, on a walk, while the coffee brews.

People who want to keep learning and keep growing — and put what they learn to use in their work and their lives. If you have a stack of books you meant to finish and a commute you'd rather not spend scrolling, it's built for you.

Tell Catalyst a topic you want to understand and it builds you a path on it — written, sequenced into days, and read aloud, the same standard as the curated ones. You set the length and the pace, and the path stays in your library.

Generating audio has a real cost, so it's metered in credits: one credit equals one minute of generated audio. Paid plans include a monthly allowance, and you can top up with credit packs whenever you like. The curated catalogue is never metered.

A small team. Every curated path is written and reviewed before it ships — no auto-published filler. The catalogue is the part we sweat over; generation is the part that lets you go beyond it.

Start free with a rotating set of introduction paths you can finish. The full curated catalogue is €7.99/mo. To generate your own paths, Learner is €17.99/mo and Professional is €29.99/mo, each with a monthly credit allowance. Credit packs are available on top.

Around five introduction paths that rotate each month, with full audio. Anything you start stays yours to finish, even after it rotates out of the free set. It's a real sample of the catalogue, not a locked demo.

Yes. Cancelling takes a couple of taps — no email, no retention maze, no questions asked.

If the price is the only thing in the way, write to info@catalystlearn.app with a sentence about your situation, and we'll work something out.

Catalyst is built for iPhone and iPad, iOS 16 or later. There is no store listing to point you to yet. What is open now: Day 1 of Stoicism: Foundations, free to read and hear, plus the essays and the topic guides. Join the mailing list and we will write when a new path lands.

Catalyst is on iPhone first. An Android version is planned — the quickest way to hear the moment it lands is to leave your email on the home page.

Day 1 of Stoicism is readable, with audio, at catalystlearn.app/lesson. The full library lives in the app.

Yes. On the Catalogue plan and up, you can download paths and listen with no signal — on a flight, on the underground, anywhere.

No. Engagement on Catalyst comes from finishing things and getting better at them — not from a streak you're afraid to break or alerts you didn't ask for. You can set one gentle daily reminder if you want it, and nothing if you don't.

Never. There are no ads, and we don't sell your data. We make money when the product is worth paying for — that's the whole model. See our privacy policy for the details.

On your device, and in your Catalyst account. Notes export to plain text and progress exports to a machine-readable file — no lock-in. You can take everything you've made with you, and ask us to delete it at any time. Our privacy policy spells out how.
