Developer Uses Claude AI to Build PosturePal Posture Scanner App

A developer has shared their experience building PosturePal: Posture Scanner, an iOS app that uses AI to analyze posture from side profile photos. The developer credits Claude AI with playing a significant role in getting the app across the finish line, particularly useful for a solo developer wearing multiple hats.
How Claude Was Used
According to the developer, Claude assisted in several key areas beyond just coding:
- Validating the initial app idea
- Writing approximately 99% of the code through "vibecoding"
- Thinking through product decisions and feature implementation
- Refining how the app communicates feedback to users
- Writing clear, non-alarmist copy for health-related content
- Discussing edge cases that hadn't been previously considered
App Features
PosturePal offers several specific features:
- AI analysis of posture from side profile photos
- Posture scoring system
- Breakdown of specific posture issues including forward head posture and rounded shoulders
- Daily exercise generation tailored to individual findings
- Weekly check-ins to track progress over time
The app is currently available for free on the Apple App Store. The developer built the app solo and found Claude particularly helpful for handling multiple aspects of development simultaneously, from technical implementation to user experience considerations.
