RectLabel 4+

I paid $0.99 when I first downloaded the app in March 2018, and now I am told to pay another $4.99 before the save function can be enabled. This is not acceptable! Though this is a good app, I won't trust the developer moving forward.

If you bought RectLabel before starting in-app purchase, you can ask us to send the version 1.96 which is just before the in-app purchase.
At first, restore purchase from app menu to make the app purchase receipt in your app to the latest one.
Then, zip and send RectLabel app(/Applications/RectLabel.app) to support@rectlabel.com.
We would check the original app version which you bought, the transaction id for your payment, and the date when your app purchase receipt was updated.
If we could confirm, we would send the version 1.96 to you.

Before launching the version 1.96, be sure to "Export settings file for the old version" from app menu.
Otherwise when you launch the version 1.96, the current settings file would be cleared because the old version cannot read the current format.
Import the exported settings file after you launch the version 1.96.

The new update version 2.58 was released.

Used this app for my Create ML object detection model. Does work well, albeit, could be better if certain things are less confusing.

I don't quite understand what the Projects thing in the Settings window is suppose to be.

But ignoring the quirks, it does deliver a workable JSON file for Create ML.

However, please update your app icon to be more Big Sur fitting. Can't stand the slightly big icon, compared to others on my dock.

Overall, keep it up on the good work!

UPDATE: Saw the update! Thank you!

Thanks for your feedback.

For the Projects tab, you can switch different objects and attributes settings for different labeling tasks.

For the app icon size, we made the app icon smaller.
We submitted the new update to Apple.
When the new update is released, we will let you know.
Thank you.

Update:
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.
