Hedgie: Learn English Grammar
Hedgie is a mobile app that helps users learn English grammar through a light, game-like experience. Users complete quizzes, get clear explanations for their mistakes, track their progress, and improve their grammar step by step without being overwhelmed by theory.
What is the project about
Hedgie was created to make English grammar easier and more interesting. For many learners, grammar is the hardest and most boring part because rules feel too heavy and exercises get tiring very quickly. That is why we made an app with short interactive tasks, simple tests, and clear feedback instead of long theory. Our friendly character, Hedgie, helps users stay motivated and move step by step through the levels.

Customer's pain
English grammar is often perceived as difficult, dry, and repetitive. Users quickly lose motivation when they are faced with rules and similar exercises without clear feedback.
The client needed a focused, easy-to-use product dedicated specifically to grammar training: fast, regular, and free from the feeling of a traditional school textbook.
Solution
We created a mobile app where grammar is taught through short quizzes, game-based tasks, and clear explanations. Users can learn at their own pace, move through levels, see their progress, and return to topics that need extra practice.
The core focus was on three things: a simple interface, instant feedback, and motivation. Hedgie helps users do more than choose answers — it helps them understand the logic behind the language and gradually reinforce grammar through consistent practice.
The process of working on a project
-
Business analysis
We analyzed the target audience and competitors in the EdTech app market. Together, we defined the core MVP flow: the user takes a quiz, receives a result, sees the mistake, and continues learning at the right level.
-
Design
We created a clean, friendly, and lightweight interface. The visual style was built around the Hedgie character, playful elements, clear buttons, and quick transitions between exercises.
-
Development
We developed the mobile app with Flutter to release the product for both iOS and Android efficiently. The app included quizzes, levels, progress tracking, a lives system, subscription logic, and basic user behavior analytics.
-
Testing
We tested the correctness of the exercises, progress tracking, subscription flows, lives system, and interface behavior across different devices. We also checked edge cases, access recovery scenarios, and overall app stability.
-
App launch in the stores
We prepared release builds, descriptions, screenshots, and store listings. After launch, the team continued collecting feedback and releasing updates with fixes and performance improvements.
Challenges we faced during the project
-
Subscription and in-app logic
The paid version unlocks additional features, so it was important to connect subscription status, access rights, and the lives system correctly.
-
Interface simplicity
The app includes multiple learning scenarios, but users should never feel lost. We kept navigation minimal and made the main actions obvious.
-
Motivation without pressure
The lives, levels, and rewards system had to encourage users without making the experience frustrating. We designed the mechanics to support regular practice rather than punish mistakes.
-
Grammar without overload
We had to explain mistakes briefly and clearly, so users could understand the rule and apply it in the next exercises.
Application functionality
Hedgie helps users learn English grammar through short quizzes, game-based tasks, and clear progress tracking. The app is designed for self-paced practice: users choose exercises, answer questions, receive feedback, and gradually improve their results.
Main functions
-
Users can see their results, completed exercises, and learning dynamics. This helps them stay motivated and understand which topics need more practice.
-
After an incorrect answer, the app shows a clear explanation so users can understand the rule and avoid repeating the same mistake.
-
Users complete short English grammar exercises and instantly see their results. This format makes regular practice easier without long lessons.
-
Exercises are organized by level, allowing users to move gradually from basic topics to more advanced grammar structures.
Levels and topics
Learning in Hedgie is structured by level — from basic topics to more advanced grammar structures. This approach lets users progress gradually, avoid being overwhelmed by theory, and reinforce each concept step by step.
Lesson structure
Within each level, users see individual grammar topics and work through them one at a time at a comfortable pace. This keeps learning clear, makes it easy to revisit weak spots, and gives users better control over their progress.
Gamification and progress tracking
Lives, rewards, and levels make the learning process more engaging and encourage users to come back every day.
Hedgie character
A friendly character guides users through the learning experience, adds personality to the interface, and makes grammar feel less intimidating.
Subscription
Premium access unlocks additional opportunities for practice, more flexibility, and a smoother learning experience without limitations.

Customer feedback
Result
We launched an educational app for learning English grammar that combines the usefulness of a training tool with the lightness of a mobile game. Hedgie helps users practice regularly, understand their mistakes, and track progress without a cluttered interface. The product also received a strong foundation for scaling: new topics, levels, characters, exercises, languages, and personalized learning mechanics can be added over time.
