Undumb is a short daily workout backed by a Harvard-educated forensic psychiatrist to keep your brain sharp when using AI regularly. Workouts help with creativity, critical thinking, and focus. We built Undumb because hard thinking is a skill worth practicing. In the modern workplace, AI tools can make work faster and are often becoming required by employers. We still want to read carefully, notice weak evidence, make our own calls, and explain what we think but the modern pace of work with AI doesn't always allow for that. Undumb offers short daily questions that help anyone deliberately train the parts of their brain that over-using AI impacts. Think of these puzzles as a workout or gym routine for your brain. Each puzzle is hand crafted with intention to help people experiencing AI-brain-drain. Your first seven workouts are free. Complete Workout 7 to unlock your Cognitive Profile, with starting scores for Creativity, Critical thinking, and Focus. As you progress further, you can see how your scores are trending over time. Membership unlocks new daily workouts after Workout 7. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
