About FastenAR

FastenAR is a professional-grade measurement tool that brings the power of augmented reality and LiDAR technology to your iPhone. Designed for mechanics, DIY enthusiasts, and anyone who works with fasteners, this app eliminates the guesswork from finding the right socket or wrench size.

The Technology

The app leverages cutting-edge iOS technologies:

  • ARKit: Apple’s augmented reality framework provides real-time camera tracking and scene understanding
  • LiDAR Sensor: Measures precise distances to fasteners for accurate sizing
  • CoreML: Custom-trained machine learning model detects fasteners with high accuracy
  • Vision Framework: Provides robust fallback detection using geometric analysis
  • Computer Vision: Advanced algorithms identify hexagonal and square fasteners automatically

Key Features

Multi-Sample Averaging: Unlike simple measurement tools, FastenAR takes three consecutive measurements and averages them, ensuring consistent and reliable results every time.

Dual-Path Detection: The app uses a sophisticated ML-first approach with automatic fallback to traditional computer vision, ensuring high success rates even in challenging conditions.

Comprehensive Database: Includes 23 metric socket sizes (6-36mm) and 16 imperial sizes (1/4"-1 7/16"), covering virtually all common fasteners.

Privacy-Focused: All measurements are stored locally on your device. No cloud sync, no analytics tracking, no data collection.

Device Requirements

FastenAR requires:

  • iPhone 12 Pro or newer (requires LiDAR sensor)
  • iPad Pro 2020 or newer
  • iOS 16.0 or later
  • ARKit capability
