Android Algebra Study App

I want to turn my high-school algebra notes into a focused Android application that learners can carry in their pocket. The app will present each topic—linear equations, quadratic functions, factoring, and so on—in a clean, distraction-free interface and keep track of how far the student has progressed through the material. The progress-tracking dashboard is the must-have feature: after every section the user should instantly see completion percentages and a simple visual indicator showing what still needs review.

Feel free to suggest elegant ways to store that data locally or in the cloud, yet keep the first version light so it runs smoothly on typical student devices. Although practice quizzes or step-by-step solutions might be interesting future add-ons, you can ignore them for this build and focus your time on a rock-solid reading experience, intuitive navigation, and reliable progress persistence.

Deliverables
• Full Android Studio project (Kotlin or Java) with well-commented source code
• Signed APK ready for Play Store submission
• Brief set-up document explaining how to update content and reset progress data

Acceptance criteria
• Topics load instantly, and progress bars update without glitches
• App installs on Android 7.0 and above with no crashes during a five-minute exploratory test
• Code passes a quick review for readability and uses standard Android architecture components

Let me know how you would structure the data model for tracking completion and what timeline you need to hand over the first test build.
