Product Analytic Tags

This feature allows engineers to see product analytics and custom performance metrics in traces. Got a signal from your APM that screen loading time took longer? With this feature you will be able to easily find the exact location on a timeline and see the root cause of the issues on the trace.

After the setup, traces will be automatically annotated with product metrics (displayed as grey flags) and placed on the timeline by PS Tool. This replaces the repeated effort required to locate and annotate each product metrics for every new trace recorded, while also ensuring that no business important metrics are left behind.This streamlines the identification of performance metrics and allows engineers to focus on root-cause analysis.

Quick Start Guide

The Quick Start Guide assists engineers during the onboarding experience by providing concise and simple instructions to help them leverage the full potential of the PS Tool.

The Quick Start Guide will be accessible to users within the tool at all times, ensuring that immediate support is readily available.

The Quick Start Guide comprises 3 main components:

  1. Introduction Video A concise, less than 1-minute video that provides an overview of how PS Tool works.
  2. Step-by-Step Guide A detailed step-by-step guide on how to perform various tasks using PS Tool. This section ensures that users gain a solid grasp of important features that can empower their analysis.
  3. Tutorial on how to identify insights Building upon the features learned in previous section, this session focuses on guiding users on how to use these features to find insights efficiently with real life examples and best practices.

R1.4 - Annotations

At Product Science, we believe that optimizing your app's performance should start with the most important screens for your business—ones that drive engagement and app retention. In this release, we are reinforcing our approach by helping our customers define the most critical user flows even before the team begins to look at the code.

  • In the new Annotations screen, even non-technical customers will be able to easily mark the beginning and end of the user flow that requires performance optimization. This is achieved by placing human-readable annotations on top of the video.
  • The new Processes x Annotations screen provides tools to connect the human-readable annotations to the code level of your app, making it easy to understand exactly where on the code level the user flow starts and ends.
  • The updated Trace Viewer screen will highlight the beginning and end of the user flow so engineers can focus on this specific part of the trace and disregard the rest.
New Screen - Annotations

The new annotation screen enables you to mark the beginning of a user flow (i.e. the user’s action) and the end of a user flow (i.e. the reaction from the app) based on your screen recording.

New Screen - Processes x Annotations

The PxA Screen enables users to connect annotations made in the previous Annotations screen to slices. This step will allow us to mark the beginning and end of the user flow on the code level. Joining videos and slices together provides solid visual cues that can’t be gained from the code alone.

R1.3 - Video

New Feature - Video preview synced with trace

With the new Video synced with trace feature you will be able to see what’s happening on the phone screen at every point of the recorded trace.

Video synced with trace feature allows you to:

  • Quickly find the beginning and end of user flows
  • See the user actions
  • Visually identify performance opportunities (like jitteriness, lags and long network requests)
  • Visually identify when the screen was updated

Seeing how your application functions in real life provides valuable context that helps to understand what’s happening - even when the code is hard to follow:

  • Ability to upload recorded video via PS Tool Web UI to a specific trace
  • Video preview thumbnails that allow you to quickly navigate video on the global timeline
  • Video tab
      •   Large Preview of the video recording
             •   Ability to play and pause video
             •   Ability to loop video
             •   Ability to delete video
Companion App
  • Ability to upload recorded video via Companion app to a specific trace
  • Added information with User Flow description
  • Added information with project platform information in the project list
  • Added information with user role
Trace Viewer
  • Vertical scroller on flamegraph, with the ability to jump to the top or bottom
  • Ability to pin a selected choreographer and made it available to anyone opening the trace
  • Disable pin-zoom for non flame chart elements
  • Updated technical copies to human readable copies for all error messages

Trace Viewer


  • Tools to prioritize and deprioritize threads so that you can better see an execution path
  • Pin thread
  • Deprioritize thread
  • Toggle to show all paths or the main execution path
  • "Show all paths" lets you see additional information about how things are executed, while "Show main execution path" lets you see the most straightforward path.

  • Toggle to dim slices outside execution paths (Hot Key: P). All functions outside of the execution path are dimmed for better visibility. 
  • Choreographer auto connections (Android only). Save your time by manually clicking on slices executed under the choreographer during the initial exploration process.


  • Slice name and connection lines styles updated for readability enhancement
  • Ability to zoom into small slices and read their names.
