Computer Vision Drives 20% User Growth for Rubik’s Cube App

21Moves: Past Client Gradient Insight


21Moves developed a Rubik’s Cube solver mobile app and was looking to augment their app features. They had a specific focus on refining the user experience.


  • Their initial build of the scanner was sufficient to get them off the ground, however had very limited capabilities.
  • The app struggled with accurately interpreting images affected by glare, leading to compromised results.
  • The scanner encountered difficulty in accurately recognising certain cubes, particularly due to variations in the size and shape of their individual pieces.
  • The app confused red and oranges on occasions, making it impossible to scan accurately.
  • Images with deep shadows presented challenges in extracting meaningful information.


  • The scanner now accurately interprets various cube configurations, even in challenging conditions.
  • Issues related to glare are effectively mitigated, ensuring precise results under all lighting conditions.
  • Accurately distinguish between colours, eliminating previous confusion between red and orange.
  • Deep shadows no longer hinder scanning accuracy.
  • Increase of users using the Computer vision app from 60% to 80%, solidifying its positioning in the market.
  • More than 500k downloads, over 25000 reviews and a 4.7 rating.


  • Analyze the customer’s image processing pipeline to identify potential points of failure.
  • Design a new image processing pipeline able to handle a wider range of situations making the APP easier to use and more reliable.
