Creating BoardBoss: A Mobile Application that Improves Boggle
How Making an iOS Application Inspired Roboflow
Before the Roboflow team was making tools for improving how developers apply computer vision to their problems, we were making our own computer vision applications. One of those applications, Magic Sudoku, even won Product Hunt's Augmented Reality App of the Year.

How to Convert Annotations from PASCAL VOC to YOLO Darknet
A bedrock of computer vision is having labeled data. In object detection
[https://blog.roboflow.com/object-detection/] problems, those labels define
bounding box positions in a given image.
As computer vision rapidly evolves, so, too, do the various file formats
available to describe the location of bounding boxes: PASCAL VOC
