Philosophy, one short reading a day.

Who it is for

Most people who want to read philosophy own a copy of Meditations and stopped around page forty. The problem is not motivation — it is that a book of aphorisms with no context, no order and no one to ask is a bad format for learning. thinkr is built for a few minutes a day instead of a reading project: one idea, applied to something real, with somewhere to take the follow-up question.

What it does

• A daily reading. One short passage from Marcus Aurelius, Seneca, Epictetus and others — enough to think about, short enough to finish before your coffee goes cold.
• A daily challenge. Five quick questions that apply the day's idea to something in your actual life, so it does not stay abstract.
• Guided courses. 151 short lessons in one clear order, from Socrates and the Stoics to Nietzsche. The first unit is free; Pro opens the rest.
• Ask the thinkers. Read sample conversations with ten thinkers for free. With Pro, ask any of 44 your own question and get an AI-written reply in the style of that thinker, not their own words.
• Watch them argue (Pro). Set two philosophers against each other on a question you care about and read the disagreement play out.
• A library. Public-domain texts and quotes you can browse, search and save. Free users get a preview; Pro opens the complete library.

Read it here first

Everything below is the substance behind thinkr, published in full and free to read without installing anything.

Common questions

Is thinkr free?

It is free to download, and some of it is free to keep: the first course unit, the daily challenge, the daily thought, sample conversations with ten thinkers, the first passage of each source text and a library preview. Pro adds live AI chat with 44 thinkers, the full 151-lesson course, councils, debates and letters.

Do I need to know any philosophy already?

No. Every passage comes with plain-English context, and Pro lets you ask a follow-up question whenever something does not land.

Is it only Stoicism?

Stoicism is the centre of gravity, but the library and the thinkers span existentialism, ancient Greek philosophy, Eastern traditions and modern thought.

Does thinkr track me?

Your reflections, saved passages and history are designed to stay on your device. The AI features send your question and recent context to the server to generate a reply; nothing is sold. The app's privacy manifest declares no cross-app tracking, and the app does not show a tracking permission prompt or use the advertising identifier. It does declare device and user identifiers, purchase history and usage data, collected for analytics, app functionality and ad-campaign measurement. The App Store listing's App Privacy section is the authoritative list of what is collected.

What makes it different from a quote app?

Quote apps give you a line a day and no way to go deeper. thinkr pairs each idea with context, a question that applies it, a course that builds on it, and a conversation you can actually have about it.
