De1App or Decaid? Choosing the right app for your Decent
Two official apps, one espresso machine. Here's what makes them different—and how to get started with either one.
Your Decent espresso machine gives you unusually precise control over coffee brewing. The app is where you choose profiles, adjust settings, connect accessories, and see what happened during a shot.
Today, you can choose between two official Decent Espresso applications: de1app, the classic app, and Decaid, our newer software platform. Both can control your DE1 and make great espresso. The difference is in how they're built, where they run, and how you can customize them.

Meet the two apps
de1app: the original Decent experience
de1app is the application that has accompanied Decent machines for roughly a decade. It's mature and familiar to long-time owners, with extensive brewing controls, graphs, profile tools, machine settings, and extensions.
Its default interface is called Insight. Insight offers dedicated tabs for Espresso, Steam, Water, and Flush, together with detailed graphs for pressure, flow, and temperature. It puts a great deal of information within reach for owners who enjoy understanding and adjusting every stage of a shot.
If your current tablet and de1app setup work well, there's no need to replace them. The classic app remains available and supported.
Decaid: a new foundation for the next decade
Decaid, introduced in 2026, approaches the same machine differently. It looks after communication with the DE1 over Bluetooth or a compatible USB connection, supported scales, brewing profiles, shot history, and other shared services. A separate user interface—called a skin—provides the controls and graphs you see on the screen.
The default Decaid skin is Streamline. It's designed to make everyday coffee-making tasks easy to reach: favorite profiles, grind and dose adjustments, an extraction graph, and recent shot information live together on the main screen. Many controls use a simple pattern: tap to use them; press and hold to see more options.
Decaid also opens up new ways for the community to build skins, plugins, and integrations through JavaScript and documented APIs. It's the foundation for Decent's future app development.
Apps and skins: what's the difference?
It's easy to think de1app = Insight and Decaid = Streamline, but that's not quite right.
The app is the software that connects to your machine and manages its data. A skin is the visual interface you use to make coffee. Both apps support different skins—including versions of Insight and Streamline.
These are not necessarily identical versions: Decaid's Streamline is a rewrite for its new platform, and skins and extensions built for one app do not automatically work in the other. Switching apps is about more than changing the look of the screen.
At a glance
| de1app | Decaid | |
|---|---|---|
| Generation | The established, classic app | The new platform, introduced in 2026 |
| Default skin | Insight | Streamline |
| Espresso profiles, graphs, and shot history | Yes | Yes |
| Alternative skins | Classic app skins | Web-based skins, including community creations |
| Extensibility | Tcl-based extensions and customization | JavaScript-based skins, plugins, and documented APIs |
| Downloads offered | Android, iPad, macOS, Linux | Android, iPad, macOS, Windows, Linux |
| Main appeal | A familiar, mature workflow | New interfaces and an expanding ecosystem |
The two apps don't yet have identical settings, extensions, or behavior in every situation. If you depend on a particular de1app extension or a carefully tuned workflow, check for an equivalent before moving over completely.
Which one should you choose?
Stay with de1app if you like your existing setup, depend on a classic extension, or use an older tablet that can't run Decaid. You can carry on making coffee as before.
Try Decaid if you have a compatible device and want to explore the latest software direction, the new Streamline experience, additional skins, or the growing plugin ecosystem.
You don't have to make a permanent choice today. Both can be installed on a compatible device for comparison. Just fully close one app before opening the other, including any background connection, so they aren't competing to connect to your DE1 or scale.
Getting started with de1app
If you're using a Decent-supplied tablet, the classic app may already be installed.
For an illustrated introduction to controls, settings, profiles, and making your first espresso, see the DE1 App Quickstart Guide.
Setting up the machine itself for the very first time? Start with the DE1 machine Quickstart Guide, which covers unpacking, water, and initial machine preparation.
Getting started with Decaid
1. Download Decaid for your device
Visit the official Decent Espresso downloads page and choose your platform. Decaid is available for Android, iPad, macOS, Windows, and Linux.
For iPad, the downloads page explains how to install with SideStep using a Mac. On Android, download the APK and install it on your tablet. Other platforms have their own installation packages and instructions.
Check compatibility before downloading. The current minimum requirements include Android 9, iPadOS 16.7, macOS 13, and 64-bit Windows 10; Linux requires a sufficiently recent distribution. Some older Decent-supplied Android tablets won't meet those requirements. On some supported older Android tablets, Decaid may display the skin in a separate browser rather than its embedded view.
2. Import your de1app data, if you have any
If Decaid detects an existing de1app installation and its data is accessible on that device, it can offer to import your settings, profiles, shot history, beans, and grinders during initial setup.
Accept the import if you want to bring your existing setup across. If you skip it, or need to import later, return to Decaid's dashboard → Data → Import from de1app. If importing manually from an older de1app folder, select the main de1plus folder rather than an individual profiles or history subfolder.
If you're moving between different tablets, your old data may need to be copied or made accessible first. Keep a backup before migrating, and remember that the two apps don't synchronize their data automatically afterward.
3. Connect your DE1 and scale
On first use, Decaid helps you select a nearby DE1. Make sure the machine is powered on and Bluetooth is enabled, choose your machine, and follow the connection prompts. If you have a supported scale, connect that as well.
Decaid remembers preferred devices so it can reconnect on later starts. If another app is already connected to the DE1 or scale, close that app first.
4. Meet Streamline
Streamline is included with Decaid and opens as its default skin. There's nothing extra to install.
Choose a profile, set the coffee dose and desired output, and use the on-screen controls or your machine's Group Head Controller to start brewing. Streamline shows the extraction graph and keeps a record of your shot.
A helpful shortcut: tap the ? button in Streamline to see explanations of the controls. Tap normally to select or activate an option; long-press a control to access additional options where available.
For a walkthrough of the interface, see the Quick Guide to Streamline.
5. Find Decaid's dashboard
Decaid's dashboard is separate from the skin. It gives you access to device management, data import/export, skins, plugins, and app settings. The way back to the dashboard differs between devices and skins.
Follow the illustrated guide: How to return to the Decaid dashboard.
When you're ready to experiment, you can also install other skins and plugins.

Common questions
Will trying Decaid delete de1app or my old shots?
Installing Decaid doesn't require removing de1app. Decaid can import supported data from the classic app. We still recommend backing up your profiles and history before a major change.
Can I go back to de1app?
Yes, if it's still installed. Close Decaid fully before launching de1app. Changes made only in Decaid, including new shots or settings, won't automatically appear in your de1app data.
Is Streamline the same as Decaid?
No. Decaid is the application; Streamline is a skin running on top of it. Streamline is included as Decaid's default interface, but you can choose other skins.
Is de1app going away?
Decaid is the direction of future development and is intended to gradually succeed the classic app. But de1app remains available and supported, so there is no immediate need to switch if you're happy with it.
Which app should I install on an older Decent tablet?
Check the operating-system version against the requirements on the downloads page. Decaid requires Android 9 or newer. An older Android 8 tablet may still be suitable for de1app, but not Decaid.
Ready to choose?
Whether you prefer the detailed, familiar controls of de1app or the flexibility of Decaid, the DE1 underneath is the same machine. Choose the software experience that makes your coffee routine more enjoyable—and feel free to explore the other when you're ready.
