What this app is. What it isn’t. What you could build.

One-liner

A lightweight, free code editor for iOS that lets users open and preview HTML/CSS files, but suffers from critical data loss, performance issues, and lack of modern features.

Strengths

Strong organic visibility for core keywords like 'code', 'coding', and 'codex'
Free pricing model attracts users who want a no-frills editor for basic file viewing
Simple interface appeals to beginners or casual users needing quick access to saved web files
Built-in preview viewer (though inconsistent) meets a niche need for front-end file inspection
High rating (4.58) suggests strong satisfaction among a subset of users despite flaws

Weaknesses

Repeated reports of irreversible data loss with no undo/backup functionality: 'It deleted everything! Twice!'
Frequent crashes and freezing, especially on moderate-sized files: 'It takes 10 seconds to open a 14kb file'
Poor performance with larger files: 'It lags hard when scrolling through big files'
Missing essential features: can't turn off word wrap, clear recent files, or sync with iCloud/OneDrive
Inconsistent or broken preview viewer: 'the viewer would just appear blank'

Opportunities

Build a version with auto-save + local backup + undo history to solve the #1 user pain point
Optimize file handling for large files using lazy loading or streaming parsing to fix lag
Add cloud sync (iCloud, Dropbox) and export options to compete with modern editors
Introduce a clean, intuitive UI focused on beginner-friendly workflows without bloat
Position as a reliable, safe alternative to Koder by emphasizing data integrity and stability
