# CMTremorResult

A result object that contains data about the presence and strength of tremors during a one-minute interval.

```
class CMTremorResult
```

## Overview

The following equation is always true: [`percentUnknown`](/documentation/CoreMotion/CMTremorResult/percentUnknown) `+` [`percentNone`](/documentation/CoreMotion/CMTremorResult/percentNone) `+` [`percentSlight`](/documentation/CoreMotion/CMTremorResult/percentSlight) `+` [`percentMild`](/documentation/CoreMotion/CMTremorResult/percentMild) `+` [`percentModerate`](/documentation/CoreMotion/CMTremorResult/percentModerate) `+` [`percentStrong`](/documentation/CoreMotion/CMTremorResult/percentStrong) `= 1.0`.

## Topics

### Reading the Time Interval

[`var startDate: Date`](/documentation/CoreMotion/CMTremorResult/startDate)

The result’s start time and date.

[`var endDate: Date`](/documentation/CoreMotion/CMTremorResult/endDate)

The result’s end time and date.

### Accessing Tremor Data

[`var percentUnknown: Float`](/documentation/CoreMotion/CMTremorResult/percentUnknown)

The percentage of time when the algorithm couldn’t make a determination.

[`var percentNone: Float`](/documentation/CoreMotion/CMTremorResult/percentNone)

The percentage of time when no tremor was detected.

[`var percentSlight: Float`](/documentation/CoreMotion/CMTremorResult/percentSlight)

The percentage of time when a tremor was likely, and the displacement amplitude was slight.

[`var percentMild: Float`](/documentation/CoreMotion/CMTremorResult/percentMild)

The percentage of time when a tremor was likely, and the displacement amplitude was mild.

[`var percentModerate: Float`](/documentation/CoreMotion/CMTremorResult/percentModerate)

The percentage of time when a tremor was likely, and the displacement amplitude was moderate.

[`var percentStrong: Float`](/documentation/CoreMotion/CMTremorResult/percentStrong)

The percentage of time when a tremor was likely, and the displacement amplitude was strong.
