Mobile App Development Process: KelimEZ Experience

As a teacher, I've observed the challenges my students face for years. One of the biggest issues was maintaining vocabulary learning motivation. To solve this problem, I decided to develop my own mobile app called KelimEZ.

Why I Built My Own App

There are many vocabulary learning apps on the market. However, finding one designed for Turkish learners that effectively uses gamification elements and is user-friendly was difficult.

💡 Key Lesson: Before starting an app idea, question whether it solves a real problem. I observed this problem for years — so my motivation never faded.

Technology Choice: Why Flutter?

I chose Flutter because:

  • Single codebase: Build both iOS and Android apps with the same code
  • Hot Reload: See changes instantly when you modify code
  • Performance: Near-native performance
  • Rich widget library: Rapid prototyping with ready components

Development Process

1. Planning and Design

Before writing code, I clearly defined what the app would do:

  • Flashcard system
  • Spaced repetition algorithm
  • Daily reminders and streak system
  • Gamification elements (badges, levels, points)

2. MVP (Minimum Viable Product)

Instead of trying to do everything at once, I released a version with only the most essential features. This allowed me to test quickly and get real user feedback.

🚀 MVP Principle: If your first version isn't embarrassing, you've launched too late.

Publishing to App Stores

Apple App Store

  • Apple Developer account: $99/year
  • Privacy policy required
  • Review process: 1-3 days

Google Play Store

  • Google Play Console: One-time $25
  • AAB format upload
  • Content rating questionnaire

Key Lessons Learned

  1. Start small: Begin with MVP
  2. User feedback is gold: Act on real data, not assumptions
  3. Consistency matters: A little work daily beats occasional sprints
  4. Write documentation: You might not understand your own code after 3 months
