Kodomo Manabi App

A Flutter kanji-learning app built for my own children.

Flutter · Dart

Problem

Off-the-shelf kanji drills are built for a general audience, so they never match where a specific child actually is.

Approach

Built and maintained the app solo in Flutter, shaping each feature around how my own children actually use it.

Outcome

Hands-on QA on real devices caught UI bugs automated tests missed — text overflow, and a setting that failed to apply consistently across screens.

Detail

A kanji-learning app for my children, built and maintained solo with Flutter.

QA is hands-on: after implementing a feature, I install it on a real emulator or device and use it the way a child actually would, which has caught real UI bugs (text overflow, settings not applied consistently across screens) that automated tests missed.
