What's New in thinkr
1.2.1
July 22, 2026
Thank you for thinking with thinkr. This update goes deeper on the learning side: • Five new course units — Medieval & Islamic thought, Epistemology, Logical Fallacies, Modern Justice, and Metaphysics. The course now spans 14 units and 165 questions. • The Timeline — see every thinker in the library laid out across 2,500 years, from Pythagoras to the present, and tap any name for a short bio. • New question types — put thinkers in chronological order, and sort ideas into schools. • Teach cards that introduce each concept before you practice it. • Earn drachmas as you learn, and spend them to refill hearts or bank a streak freeze. New here? Open to Today's Challenge — five quick questions a day — then work through a guided course from the Stoics to the existentialists, and reason with history's greatest minds.
