This project helps you test checkout changes and measure which version works better. It uses simple test results, customer behavior data, and business impact checks so you can make a clear choice.
Use it when you want to compare two checkout flows, test a new button, or check if a change helps sales.
Before you start, make sure you have:
- A Windows PC
- Internet access
- About 200 MB of free space
- Permission to open downloaded files
- Microsoft Edge, Chrome, or another browser
For best results, use Windows 10 or Windows 11.
Go to the releases page and download and run the file for Windows:
On that page, look for the latest release and choose the Windows file. If there are more than one file, pick the one that ends in .exe or the Windows installer file.
- Open the file you downloaded.
- If Windows asks for permission, select Run or Yes.
- If a setup window opens, follow the steps on screen.
- Choose the install folder if asked, or keep the default.
- Finish the setup.
- Open the app from the Start menu or the desktop.
If Windows shows a security message, select the file anyway only if you got it from the releases page above.
After you open the app, follow these steps:
- Load your test data.
- Choose the checkout versions you want to compare.
- Start the analysis.
- Review the result for conversion rate, confidence, and business impact.
- Save or export the report if you need to share it.
The app is built for simple A/B testing workflows, so you can move from data to decision in a few steps.
This project can help you review:
- Conversion rate changes
- Test result strength
- Checkout performance
- User behavior patterns
- Expected revenue impact
- Risk of choosing the wrong variant
It uses methods such as:
- Z-test
- Logistic regression
- Bayesian analysis
- Business impact estimation
These methods help you compare versions in a structured way.
Use this app if you want to:
- Test a new checkout button color
- Compare a short form against a long form
- Check if a one-page checkout improves sales
- Measure if a discount message changes behavior
- Review if a design change helps or hurts conversions
It works well for ecommerce teams, analysts, and store owners who want a clear result.
A simple workflow looks like this:
- Collect checkout data from two versions.
- Open the app.
- Import the data file.
- Pick the test type.
- Run the analysis.
- Review the main metrics.
- Make a decision based on the result.
If your data is clean and complete, the result is easier to read.
For the best results, use a file with rows for each user or session. A common format includes:
- User ID
- Variant name
- Converted or not converted
- Session date
- Order value
- Device type
The app can work with common CSV files that follow this style.
The project is set up to help you see:
- Which variant converts better
- How large the difference is
- Whether the change may be real or due to chance
- What the likely effect is on revenue
- Which version is safer to launch
If the app does not open:
- Make sure the download finished
- Try opening the file again
- Check that you selected the correct Windows file
- Restart your PC and try once more
- Use the latest release from the releases page
If your data does not load:
- Check that the file is a CSV or another supported format
- Make sure the column names are clear
- Remove blank rows at the top of the file
- Save the file again and retry
If the results look strange:
- Check that both versions have enough users
- Make sure conversion values use only valid values such as 0 and 1
- Confirm that each row represents one user or one session
This app is meant to help you analyze your own test data. Keep your files in a safe place and use trusted sources for downloads. If your team handles customer data, follow your own privacy rules before sharing reports.
