Ango Hub App

Use the Ango Hub App to label and review classification and data collection tasks from iOS and Android devices.

The Ango Hub App is the mobile version of Ango Hub for iOS and Android. It lets users work on assigned projects from their phone or tablet, label classification tasks, review tasks, collect photos, videos, and audio through upload boxes, and track uploads until they are submitted.

The app is designed for workflows where a mobile device is the natural place to collect or review data, for example field data collection, handheld video capture, audio capture, and quick classification work away from a desktop computer.

The Ango Hub App is not publicly available yet. This documentation describes the app's planned functionality and will apply once the app is released.

The Ango Hub App is not a full replacement for the Ango Hub web app. Project setup, ontology setup, user management, imports, exports, and advanced annotation workflows are still performed from the web app.

The Projects tab shows the projects assigned to the current user in the selected organization.

What you can do from the app

From the Ango Hub App, users can:

• Sign in with their Ango Hub account, Google sign-in, or SSO.

• Complete two-factor authentication when it is enabled on the account.

• Switch between organizations they belong to.

• See assigned projects and open project details.

• Start labeling or reviewing from accessible Label and Review stages.

• Open individual tasks from the task list.

• Answer mobile-supported classification questions.

• Capture or select photos, videos, and audio for upload-box questions.

• Save drafts, submit label tasks, accept or reject review tasks, and skip tasks when skipping is enabled.

• View project instructions, task attachments, task information, stage history, and task issues.

• Create issues, reply to existing issues, and resolve issues.

• Monitor pending uploads, pause and resume uploads, and retry failed uploads.

What the app supports

The mobile editor supports image, video, audio, PDF, and text assets for viewing. It supports the following classification tools:

• Radio

• Checkbox

• Single-select dropdown

• Multi-select dropdown

• Tree dropdown

• Text

• Upload box

The app also supports nested classifications and repeatable classification groups when the underlying classification type is supported on mobile.

What still requires the web app

Use the Ango Hub web app for:

• Creating projects and configuring workflows.

• Creating or editing the project ontology.

• Importing assets.

• Exporting annotations.

• Drawing annotations such as bounding boxes, polygons, segmentation masks, entities, relations, and other non-classification tools.

• Projects using required classification tools that are not yet supported on mobile.

• Projects with custom JavaScript label validation enabled.

• Asset types that the mobile app cannot display.

If a project or task uses a required feature that is not supported on mobile, the app will tell the user to continue from the web client.
