RectLabel Pro 4+

This app has so many capabilities and it's very easy to use. I mainly recommend this app over others becuse it can 1) output in COCO format (Json file), 2) can do keypoint and mask annotations and 3) can overlay depth maps to images. I love how there are so many shortcuts for most actions, and I can always change the shortcuts to my liking. I also use this app with Apple's side car to label on my iPad. I gave a tutorial- "how to use RectLabel" to 8 of my undergrads, and they all thoguht it was intuitive and easy to use. Customer service has been responsive, super helpful and has always addressed a lot of questions/concerns. The app is ALWAYS getting new bells and whistles added to it. The company listens to my feedback/needs and is willing to add new capabilities accordingly. I am very pleased with RectLabel, and would highly recommend it.

Thanks for writing the review.
In the latest version 2024.09.20, we improved exporting features of Create ML, Classification, COCO, YOLO, DOTA formats so that you can resize images and split them into train/val/test folders at once. You just have to drag and drop each train/val/test folder to Create ML.

We have tried a number of online labeling tools but none of them is as immediately powerful and performant as RectLabel. Having it run locally makes it extremely responsive, and the developers are quick to respond to any questions or issues.
For the price, this tool is a steal!

When annotating you cannot change classes. Take the proper steps in the UI and it still won't change the annotations class label. Makes the application useless.

Thanks for writing the review and we apologize that changing the object class does not work for you. If you were using 1-click buttons on the label dialog, the problem was fixed in the latest version. For other cases, could you write the problem on our Github issues page?

Update:
In the latest version 2024.09.20, we improved the YOLO format so that you can save object names combined with attributes in "_name.txt" file. When train, use Export YOLO feature and check on the "Export only used names" option, all "_name.txt" files are scanned and the new objects table created, based on the objects table, each object index is written in each YOLO text file.
