AnkiHeat

A beautiful heatmap widget that lives on your home screen. Connect AnkiDroid once, study like normal, and watch your progress fill in day by day.

This project took me through the full app development lifecycle and in to other business areas such as online marketing and customer support. App was made using spec-driven development workflow.

User Personas & Use Cases

Primary User: Dedicated Anki learners who use AnkiDroid for spaced repetition (students, language learners, etc.).

Core Use Cases:

• As a Learner, I want to see my daily review activity on my home screen so that I can maintain my study streak without opening the full app.
• As a Learner, I want to create a “study template” once (defining deck, colors, and fonts) and deploy it across different widget sizes on my home screen.
• As a Learner, I want to tap my widget to launch AnkiDroid immediately so that I can begin my daily reviews with zero friction.
• As a Learner, I want to archive old widget designs so that my main gallery stays focused on my active subjects.
