Getting started

Installation​

Install the CLI with:

curl https://get.flashlight.dev/ | bash

Simple usage​

🔌 Plug-in an Android device to your computer. Open any app.

Then the simplest way to get started is to use our Flipper plugin or use the measure command:

1. Run the measure command​

flashlight measure

Do things in your app, then press w.
A JSON file full of performance measures will be written for you.

2. Open the web report​

From this JSON file, you can generate a full web report with your performance score 

flashlight report <your results.json>

See more on how to customize reports, generate comparison views... here .

Going further​

You might have noticed that your performance score is completely dependent on how you use your app, and might change quite a bit.

Performance measures are usually not deterministic, the best way to combat this is to:

  • run several iterations and average results
  • automate user behavior

But let's face it, that's just super cumbersome to do!
Luckily we got you covered:
