Question

Pulse

Answer 1

In lifecycle, users coming into the door vs. users coming out of the door , so this is new plus resurrected over dormant

Answer 2

A project is a destination that collects all of your event data from your product. However, it is extremely important that you have a minimum of two projects in your Amplitude organization: a test and production project. You should always heavily QA your instrumentation in your test project before sending it to your production project in order to catch any instrumentation bugs and keep test data separate from production data.

Answer 3

tells you what percentage of users come back on a specific day.

Answer 4

Unbounded Retention tells you what percentage of users come back on a specific day or later.

Answer 5

The usage interval shows the percentage of active users that have performed the selected event(s) with a median frequency of X days/week/month. To be counted in this view, users must perform the selected event on at least 2 separate days in the time range. Discovering your usage interval is important so you can accurately draw conclusions about your retention numbers. Some products are built to be used daily, while other might be used much less frequently.

Answer 6

being active means triggering at least one active event during the calculated time period

Answer 7

if i wanted to see the breakdown of event distribution properties

Answer 8

By default, an active user is a user who has logged at least one event on a particular day. You can edit this definition by marking certain events as inactive.

Answer 9

A new user is a user who has logged an event for the first time (this includes inactive events). The time of when the user is new is the time of when they logged their earliest event.

Answer 10

A unique user is a distinct individual to whom events are attributed. Amplitude uses a system of identifiers to count unique users. In the raw data, unique users are counted using amplitude_id.

Answer 11

A session is a period of time that a user has your app in the foreground. By default, events within 5 minutes of each other are combined into a single session on a mobile app. On web, events within 30 minutes of each other are combined into a single session.

Answer 12

An event is an action a user takes in your app. This could be anything from pushing a button, completing a level, or making a payment. Depending on your type of app you should aim to track between 15 and 200 events to get a full understanding of how users are engaging with your app.

Answer 13

Reflects more detailed information about an event at the time it was tracked. These properties highly depend on the type of app you have and the specific information you think is necessary for understanding a particular event. General keys we have seen are cause, description, category, type, duration, level, % completed, name, count, source, status, from, number, lives, authenticated, error, rank, action, and mode.

Answer 14

Reflects traits about the individual person using your app. Examples of custom user properties are age, gender, email, locale, referral source, plan type, number of photos uploaded, number of units of in-game currency, and current level in a game. The most important thing to remember is that these user properties reflect the state of the user and apply across all their events.

Answer 15

A set of users with shared behaviors and properties, e.g. users who have made at least five purchases within the last 30 days.

Answer 16

Measures the number of different days/weeks a user performs an event in each week/month interval.

Answer 17

Measures how often your users are returning to your app over some timeframe.

Answer 18

A unique ID used to identify a user, e.g. email address or username.

Answer 19

A device-specific identifier. For iOS, the Device ID is the identifierForVendor (IDFV). This does not persist across installs. For Android, we generate a random Device ID that gets stored locally on the phone. However, there is a flag to use the Advertising Identifier as the Device ID if you want. The Advertising Identifier does persist across installs but users have the option of changing this identifier on their devices at any time. See a detailed explanation for how the value is obtained here.

Answer 20

A counter distinguishing events. Event IDs are associated with the Device ID.

Answer 21

Represents the number of milliseconds since epoch (UTC) of when the first event of the session occurs.

Answer 22

Any event you are tracking in Amplitude that has not been marked as inactive.
