# Analysis tools at a glance

Every Onform analysis tool in one place: slow motion, drawing tools, angles, Compare, Voice-over, transcripts, the 2D skeleton and golf 3D, and which apps have each.

Works on: iPhone, iPad, Android and web. The iPhone and iPad app has every tool; Android and the web app have fewer, as the tables show.

Open any video to use these tools. **Yes** means the tool is there, **No** means it isn't, and **Not confirmed** means we're still checking. For every other feature, see [What works on which app](/how-onform-works/what-works-on-which-app.md).

## Playback

| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------- | ------- | --- |
| Slow motion    | Plays the video slower or faster. On iPhone and iPad, tap the speed button and pick from 2× down to 1/8×.                                                                                                                                         | Yes             | Yes     | Yes |
| Frame by frame | Steps the video one frame at a time, so you can stop on the exact moment: impact, take-off, release. On iPhone and iPad, use the arrows either side of play, or drag across the video. On the web you can also use the left and right arrow keys. | Yes             | Yes     | Yes |
| Loop           | Plays the video over and over.                                                                                                                                                                                                                    | Yes             | Yes     | Yes |

## Drawing tools

On iPhone and iPad, tap the pencil to open the drawing toolbar. It holds five tools at a time, plus **Undo** and **Clear**. Tap any of the five to swap it for another tool and choose its color and line thickness. Double-tap a color to change it. The toolbar remembers what you picked.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.onform.com/how-onform-works/analysis-tools.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
