WDYL - What Did You Learn

A beautiful and intuitive Flutter application for tracking your daily learning journey. Capture insights, discoveries, and progress with an elegant interface designed to make reflection a daily habit.

🎯 Purpose & Motivation

In today's fast-paced tech world, we learn small technologies, frameworks, and tools every day, but often forget these learnings when it comes time to update our resumes. WDYL solves this problem by providing a structured way to track your daily learning achievements.

The Resume Advantage: Export your learnings in PDF, CSV, and JSON formats, then feed them to any Large Language Model (LLM) to generate well-crafted resume paragraphs. Let AI help you articulate your continuous learning journey professionally and comprehensively.

Note: I created this app initially for my own personal use, but later decided to release it as open source because I found that there was no app which has simple WDYL and export function. I also wanted to keep it free from Google Services Framework (GSF) to maintain user privacy and independence.
