What is Patrick Zedler?
Patrick Zedler is the personal website of Patrick Zedler, a creative coder and digital artist from southern Germany. He describes himself as a student working toward a Bachelor of Science at HTWG Konstanz, and says his goal is to build solutions that combine artistic creativity with modern digital technology. In practice, the site is a portfolio: it showcases his Android apps, open-source projects, and craft work, with links to Google Play and GitHub for downloads and source code.
What you'll find there
- Android apps and live wallpapers — for example, Lamartine, described as an interactive 3D live wallpaper based on Vincent van Gogh's painting "The Yellow House."
- Open-source software — such as Grocy Android, an Android client for the self-hosted grocery and household management tool grocy.
- Physical craft — a "Wood Carving" section with gifts carved and milled from lime wood and finished with non-glossy acrylic paint.
- Project updates — recent highlights on the homepage, with more detail in the main menu categories and ongoing work tracked on GitHub.
Who it's for
The site suits people looking for Android apps or live wallpapers from an independent developer, self-hosters interested in an Android front end for grocy, and anyone curious about open-source code or handmade woodwork. If you want a company, product documentation, or commercial support, this is a personal portfolio rather than a business site.
A useful next step
Start with the recent highlights on the homepage, then use the main menu categories to see the full range of projects. If a project interests you, the GitHub link is the better place to check activity, issues, and source code before relying on it — a sensible habit for any independently maintained app.
What Android apps has Patrick Zedler developed?
Patrick Zedler's site highlights two Android apps in particular: Lamartine, an interactive 3D live wallpaper based on Vincent van Gogh's painting The Yellow House, and Grocy Android, an open-source Android client for Grocy, a self-hosted grocery and household management system. Both are also referenced as available via Google Play or GitHub from the homepage at Patrick Zedler.
The page also lists Wood Carving, but that is a craft project—carved and milled lime-wood gifts painted with non-glossy acrylic—not an Android app.
Quick comparison
| Project | Type | What it does | Who it's for |
|---|---|---|---|
| Lamartine | Android live wallpaper | Interactive 3D wallpaper based on The Yellow House | People who want an art-focused, animated home screen |
| Grocy Android | Android app (open source) | Client for a self-hosted Grocy grocery/household server | Grocy users who want mobile access to their own setup |
| Wood Carving | Physical craft | Hand-carved and milled lime-wood items | Not an app |
How to choose / next step
- If you want a visual, artistic phone customization, look at Lamartine.
- If you already run Grocy at home and want to manage groceries from your phone, Grocy Android is the relevant app—note that it depends on your own Grocy server rather than a hosted service.
- To see the full, current list (including anything newer than these highlights), browse his Google Play developer page or GitHub profile, linked from Patrick Zedler.
How can I download and use Patrick Zedler's Android apps?
Patrick Zedler distributes his Android apps through Google Play, and the source code for several projects is available on GitHub. The homepage points visitors to both, so those are the two official channels to start with.
What you'll find there
From the homepage, the highlighted projects include:
- Lamartine – an interactive 3D live wallpaper based on Vincent van Gogh's painting The Yellow House.
- Grocy Android – an open-source Android client for Grocy, a self-hosted grocery and household management tool.
- Wood Carving – a non-app project: carved and milled lime wood pieces painted with non-glossy acrylic paint.
How to get and use the apps
- Open Google Play and search for the app name (for example, "Lamartine" or "Grocy Android"), or browse Patrick Zedler's developer page there.
- Install the app like any other Android app, then open it and follow its in-app setup.
- For Grocy Android specifically, you'll need your own Grocy server running first — the app is a client, so it connects to a self-hosted instance rather than providing the service itself.
- If you'd rather build from source or check what's changed, look at GitHub for the project repositories.
A quick decision guide
| Your goal | Where to go |
|---|---|
| Just install and use an app | Google Play |
| Read or build the code | GitHub |
| Run Grocy Android | Set up a Grocy server, then connect the app |
If you only want to try the live wallpaper, Google Play is the fastest route — no server or extra setup is involved. If you're evaluating Grocy Android, confirm you're comfortable hosting Grocy yourself before installing, since the app depends on it.
What is the Grocy Android app and how does it work?
Grocy Android is an open-source Android client for Grocy, a self-hosted grocery and household management system. In practice, Grocy runs on a server you control—typically a home server, NAS or Raspberry Pi—and the app is the mobile front end you use to interact with that data. The app is listed on Patrick Zedler as one of his projects, alongside his live wallpaper and wood-carving work.
What it does
The app gives you a phone-friendly way to manage household inventory: what food and supplies you have, what you've used, and what you need to buy. Because it's a client rather than the whole system, the actual database and business logic live on your Grocy server. The Android app handles the day-to-day tasks—checking stock, adding or consuming items, and managing shopping lists—while your server keeps the data.
How it works in practice
- You install and run Grocy on your own server (or use an existing Grocy instance).
- You install the Grocy Android app on your phone.
- You connect the app to your server by entering its address and credentials.
- From then on, the app reads from and writes to your server, so any changes sync across your devices.
A typical scenario: you're at the supermarket, open the app, and check your shopping list. Back home, you scan or search for an item and mark it as consumed, which updates the stock count on your server. Later, on a desktop browser, you see the same up-to-date inventory.
Who it's for
- People who already run Grocy and want a native Android experience instead of the web interface.
- Privacy-conscious users who prefer self-hosted software over cloud services.
- Households that want shared visibility into what's in the pantry and what needs restocking.
Trade-offs to consider
The main trade-off is setup and maintenance. Because Grocy is self-hosted, you need a server that stays reachable, and you're responsible for backups, updates and network access. If you don't already run Grocy, the app alone won't do anything. If you do, the app is a convenient mobile companion rather than a replacement for the server.
Next step
If you already have Grocy running, install the app and point it at your server's address. If you don't, start by setting up Grocy on a home server or NAS, then add the Android client. You can find the app and related projects through GitHub or the Google Play listing, both linked from Patrick Zedler's site.
What is Lamartine: Van Gogh Live Wallpaper and how does it work?
Lamartine: Van Gogh Live Wallpaper is an Android live wallpaper by Patrick Zedler that turns Vincent van Gogh's painting "The Yellow House" into an interactive 3D scene rather than a flat background image. According to the project description on Patrick Zedler, it is built as an interactive 3D live wallpaper based on that oil painting.
How to think about using it
- What it is: A phone background that renders a painted scene with depth and motion.
- How it likely works in practice: A 3D reconstruction of the painting's composition is displayed behind your home screen, and you interact with it through touch or device movement. The page evidence confirms the 3D and interactive nature but does not detail specific gestures, so treat exact controls as something to check in the app itself.
- Where to get it: The site points to Google Play and GitHub as the places to download Android apps or browse source code.
Who it suits
- People who want an art-themed wallpaper with more visual depth than a static crop.
- Android users comfortable installing a live wallpaper and adjusting home-screen settings.
- Anyone interested in creative coding who wants to see how a painting can be rebuilt in 3D.
Trade-offs to expect
- Live wallpapers generally use more battery and system resources than static images.
- A 3D scene may compete visually with icons and widgets, so a simpler home-screen layout often works better.
- If you prefer a clean, minimal look, a static wallpaper may be the better choice.
A practical next step
If you want to try it, search for the app on Google Play from your Android device, or look for the project on GitHub via the links on Patrick Zedler to check its current status and source. Before committing, test it for a day and watch battery usage; if it drains too much, switch back to a static wallpaper.
