The precise level, exact ruler, and smart protractor in one app. The ultimate multitool for DIY enthusiasts, campers, and professionals.

Whether you want to hang pictures perfectly straight, align the washing machine with millimeter precision, or level your camper – this handy app turns your Android smartphone and optionally your Wear OS smartwatch into a reliable measuring tool. Forget the old folding rule or tape measure! All completely without annoying ads and without data collection.

The highlights at a glance:

📏 3-in-1 Level: Use the classic bullseye level for surfaces or the tubular levels for exact edges and slopes. The perfect spirit level for any DIY project.

⌚ Wear OS Integration (Pro): The absolute gamechanger for leveling! Connect your Galaxy Watch, Pixel Watch, or other Wear OS watches and get the live display (level & decibel) right on your wrist. Synchronized in real-time – ideal when screwing under cabinets and you can't see your phone.

📐 Precision Ruler: Measure objects and distances directly on your display. The digital ruler can be calibrated exactly to your screen size.

🚀 NEW: The Wireless Inspection Camera (Endoscope)!

Turn your phone into an endoscope for hard-to-reach places (cable ducts, engines, behind cabinets). Place this device, scan the generated QR code with a second phone or tablet on the same Wi-Fi, and watch the video live stream comfortably in your browser – flashlight control included!

🔦 AR Laser Level (Pro): Project a virtual laser plumb line directly into the room via your camera using cutting-edge Augmented Reality. Perfect for aligning objects perfectly straight on the wall, even over longer distances.

📐 Protractor (Pro): Simply place your phone on the object and measure the exact angle and inclination in degrees.

🔊 Decibel Meter (Pro): Check volume and noise pollution in dB in real-time. Ideal for the workshop, construction site, or a quick noise check.

🌙 Premium Dark Mode: A high-contrast, dark design (OLED-optimized) that saves battery and is perfectly readable even outdoors in the sun.

🛡️ 100% Privacy: No registration, no tracking, no ads. Your measurement data remains offline and only on your device.
