## What is Touch Annotator?

Touch annotator is an image annotation platform for object detection. It automatically manages formatting the annotations. Touch Annotator also has some other useful features:

1. the ability to delete bounding boxes by holding them.
2. the ability to rename label by holding label. This renames all previously created bounding boxes.
3. the ability to select a label by tapping on a bounding box that belongs to it.

1. Create ML
2. Turi Create
3. CSV with the origin on the top left corner
4. CSV with the origin on the bottom left corner
5. CSV with the origin on the bottom right corner
6. CSV with the origin on the top right corner
more formats are going to be added over time. To request a format, please reach out to us at support@intersection.software

### 5/5 — amazing app!

*2020-05-27, version 1.4*

very good format and easy to use, very helpful. thank you!

### 1/5 — Doesn’t really work

*2019-10-30*

Ok so it’s not usable due to the data being wrong? Why when I place a box on the left edge does it not have a x coordinate of zero? Failed :(

**Developer response:** Hi Dean,

I’m sorry to hear that you’re having issues with the app. It would be great if you can send us the image and the annotations file so we can track down the issue. Did you experience other issues that made the app unusable to you?

Please send your feedback to support@intersection.software

### 5/5 — Great!

*2019-10-25, version 1.0*

Fantastic app that makes my life so much easier.

### 5/5 — Easiest Annotator to use!

*2019-10-24, version 1.0*

The Touch Annotator is my saviour. I have to create a lot of annotated images of the human body in detail for teaching purposes. It is incredibly easy and intuitive to use.

### 1/5 — Poor experience

*2019-10-24*

The application works bad with voiceover on. Please research accessibility in iOS and update your app. It is very easy to do and I see no reason for omitting accessibility labels. Also the bounding box is to thin which makes it difficult to see.
