The Streamline Skin, designed by Pulak and programmed by John Buckman, is a next-generation interface for the Decent Espresso (DE1) app. Its primary philosophy is "one tap to do everything," prioritizing speed and simplicity over the data-heavy "Insight" default. Despite its minimalist aesthetic, it features high functionality, including five quick-switch profile favorites, Light and Dark modes, and a "Zoomed" view that focuses purely on the extraction chart.
Key features include:
Streamline is designed for daily efficiency, making complex espresso variables accessible through an elegant, user-friendly layout suitable for both home enthusiasts and fast-paced cafe environments.

The "Upload to Visualizer" extension is a powerful community-driven tool for the Decent Espresso (DE1) app that allows users to automatically sync their shot data to the Visualizer.coffee platform. This integration transforms raw extraction data into a shareable, visual format for deep analysis.
The Visualizer extension turns individual espresso sessions into a collaborative learning experience, helping users refine their technique and achieve greater consistency through data-backed insights.

The "Describe Your Espresso" (DYE) extension is a built-in tool for the Decent DE1 app designed to transform your shot history into a detailed digital coffee journal. By activating this extension, users can manually log critical variables such as bean type, roast date, flavor notes, grinder model, and specific grind settings for every extraction.
The extension significantly streamlines workflow with a "propagate beans" feature that auto-populates data for subsequent shots when using the same coffee. While the DE1 automatically records technical data (pressure, flow, and temperature), DYE adds the human element of taste and technique. For advanced analysis, it integrates seamlessly with the Visualizer.coffee community, allowing baristas to upload their logs, track their progress over time, and even download shot profiles from other users to replicate successful results.

In 2016, we commissioned John Weiss to develop a custom software suite for rigorous filter basket analysis. To support the coffee community, we've released this tool as a patent-free, open-source project. We use this exact software for our own quality control, and we're excited to share it with manufacturers and data-driven home baristas alike.
The software performs a deep dive into basket geometry using high-contrast photography. By placing a basket against a uniform light source, the program can:
Compatible with Windows and Linux, we provide a pre-compiled Windows binary for quick setup. You just need a high-resolution PNG of your basket and a Python environment. If you use our code publicly, please credit John Weiss and Decent Espresso.

The Decent App Explained guide provides a comprehensive tour of the software that powers the DE1 espresso machine, designed to help both beginners and advanced users master its capabilities.
The guide introduces the Insight skin (the default interface), which uses a series of functional tabs:
A major focus is on the Presets menu, where users can select or create coffee profiles using three distinct modes:
The app's functionality is further expanded through popular community extensions like Describe Your Espresso (DYE) for shot logging and Upload to Visualizer for deep data analysis. Finally, the guide covers critical maintenance workflows, including cleaning, descaling, and sensor calibration, ensuring the machine remains in peak operating condition.
This overview underscores the DE1's "open-source" spirit, showcasing how interchangeable skins and software updates keep the machine at the cutting edge of espresso technology.
