Project Overview
Leftify is a customizable note-taking app designed specifically with left-handed users in mind, while remaining fully adaptable for right-handed use. The app creates an inclusive, frictionless writing experience by addressing a long-standing accessibility gap in everyday digital note-taking tools.
The Problem
Digital Interface Friction: Existing note-taking apps lack reliable palm rejection, causing accidental palm touches and constant eraser triggers that interrupt writing rhythm.
Control Obstruction: Traditional top toolbars place primary controls (like color pickers and font selectors) directly under the resting palm/wrist of left-handed writers, causing constant screen blockage.
Paper & Digital Limitations: Physical notebooks cause hand strain and smudging, while existing digital apps lack personalized legibility options for messy handwriting.
The Solution
Leftify minimizes physical hand strain and digital interference through a fully customizable workspace designed for flexible, accessible note-taking:
Adaptive Top Toolbar & Mirrored Controls: Features a top positioned toolbar where key controls, such as the Color Picker and Font Size Selector mirror across the bar when toggling between left- and right-handed modes to eliminate palm occlusion.
Seamless Continuous Page Creation: Automatically appends a new page upon scrolling down, keeping the user in an uninterrupted creative flow without needing manual page-creation steps.
Deep Workspace Personalization: Customize background colors, paper line types, and fonts to fit individual writing styles.
Multi-Input Compatibility: Full support for stylus freehand drawing, typing, and external keyboard input.
Smart Handwriting Conversion: Instantly converts freehand writing into clean, legible text using custom fonts.

User Testing & Research
Unguided Usability Testing: Tested prototypes with left-handed users given specific tasks without pre-demo instructions to evaluate natural interface intuitiveness.
Iterative Fixes: Monitored task completion bottlenecks to optimize gesture sensitivity and layout control placement.
