We've upgraded our firewall to provide better protection against potential threats. This update strengthens our security infrastructure and helps safeguard your data with improved filtering and monitoring capabilities. No action is required on your part—the upgrade is now live.

We're excited to introduce dark mode across the entire app, giving you a comfortable viewing experience in any lighting condition. Whether you're studying late at night or in a bright environment, you can now choose the theme that works best for you. We've also added a new study streak tracker that helps you build consistent study habits. Set daily goals, track your progress, and view detailed weekly statistics to stay motivated and accountable. Finally, we've completely redesigned your dashboard to organize progress by AP exam topic area. This makes it easier to identify which subjects need more attention and celebrate the topics you've mastered.

We've added a powerful new spaced repetition system to help you master calculus formulas and theorems. The flashcards cover limits, derivatives, integrals, and series, using proven learning science to optimize your study sessions. The system intelligently tracks your mastery for each topic and sends timely reminders before concepts start to fade from memory. This ensures you retain key material long-term while spending your study time efficiently on areas that need the most work.

We've resolved a critical bug in the integration by parts solver that was causing incorrect signs to appear during the second iteration of calculations. Your step-by-step solutions will now display the correct mathematical notation throughout the entire solving process. Additionally, we fixed an issue where u-substitution steps were disappearing on mobile devices. All solving steps are now properly visible across all screen sizes, ensuring a seamless learning experience whether you're studying on a phone, tablet, or desktop.

We've added a powerful new interactive graph plotter designed specifically for calculus students. You can now visualize derivatives and integrals with real-time feedback as you explore different functions. Drag points directly on the graph to see the slope of tangent lines update instantly, giving you immediate visual insight into how derivatives behave. The plotter supports polynomial, trigonometric, exponential, and logarithmic functions, covering the full range of calculus coursework. This tool transforms abstract concepts into tangible, interactive learning experiences, helping you build deeper intuition for calculus fundamentals.

We're excited to introduce a comprehensive AP Calculus AB practice exam designed to prepare you for test day. The exam includes 45 multiple choice questions and 6 free response questions, mirroring the actual AP exam format and difficulty. The practice exam features a proctored timed mode set to 3 hours and 15 minutes, giving you an authentic test-taking experience. Our auto-grading system instantly evaluates your responses and provides a detailed score breakdown organized by topic, helping you identify strengths and areas for improvement. Use this resource to build confidence, refine your test-taking strategy, and focus your final study sessions where they matter most.
