Overview

A practical idea with environmental impact.

Problem

Shower time is easy to lose track of

People often use more water than they realize simply because time passes quickly in daily routines. Flowless focuses on making that hidden cost more visible.

Solution

An app that encourages awareness

As an Android app, Flowless is designed to help users pay attention to how long they spend showering so they can make more sustainable choices.

Impact

Small habit changes can save resources

The project connects software with environmental responsibility, showing how a simple tool can support better long-term habits.

Why It Matters

Flowless reflects a science-minded approach to everyday behavior.

Technology meets sustainability

Flowless uses software as a way to address a real-world environmental issue rather than treating coding as an abstract exercise.

Behavior change through measurement

By focusing on shower duration, the project turns a daily habit into something users can notice, manage, and improve.

A strong real-world project direction

The project shows Annabelle combining scientific thinking, app design, and practical problem solving in one focused idea.

Project Direction

Flowless turns awareness into action by helping people see how a few minutes can become meaningful water savings.
