MoldQueen

MoldQueen is a connectivity application developed by Dr. Jens Richter, packaged as a single Android APK of version 0.1 weighing in at 26.86 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 26.86 MB, so it installs quickly even on modest connections.
3. This build is signed by "Dr. Jens Richter" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

• A model-specific Excavator (Mould King 13112) dashboard with left and right tracks, arm, front arm, rotation, and bucket.
• Generic, model-agnostic layouts (a 12-axis controller and a brick-style gamepad) that drive any Mould King MK4 model on these hubs.
• Proportional drag joysticks and press-and-hold buttons.
• Per-channel speed caps, channel inversion, and a RAW channel view for direct control.

• Pick a motor profile (tracked vehicle, car with steering, or custom) and a motor count.
• The app assigns each motor to a slot and channel; adjust any row by hand.

• Pair a Bluetooth controller (for example a DualSense) and steer with the sticks.
• Touch and gamepad work interchangeably.

• An emergency STOP control that cuts all motion at once.
• Auto-neutral keepalive: every active channel must be refreshed continuously, so a channel that stops being refreshed returns to neutral on its own. A dropped connection or a released control coasts back to a stop instead of running away.

• Six interface languages: English, German, Chinese, Korean, Spanish, and French.

• Free software under the MIT License; the full source is on GitHub.
• The Mould King MK4 protocol was reverse-engineered for interoperability with hardware the author owns, for educational and personal use.
• Builds on J0EK3R's MIT-licensed MouldKingCrypt work, ported byte-for-byte and verified against the stock app's adverts.
• A private, independent, unofficial hobby project. Not affiliated with, authorized by, endorsed by, or sponsored by Mould King; "Mould King" is used only descriptively for interoperability.

Is MoldQueen free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does MoldQueen require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is MoldQueen safe to install?
We link to the exact APK published by Dr. Jens Richter. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update MoldQueen?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded io.github.jrichter24.moldqueen.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «MoldQueen» by Dr. Jens Richter and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
