NightWalk Depth Scanner vs Heightly

NightWalk transforms your iPhone into a powerful tool for exploring dark environments. Using the LiDAR sensor, the app creates real-time depth-based visuals, helping you understand the space around you—even in total darkness. Take clear photos and record videos of what the LiDAR sees, and save them right to your device. Switch between color palettes, including grayscale and enhanced contrast modes, to match your preferences or lighting conditions. Need to measure distance? Tap the Distance button to activate a center-target reticle that instantly displays how far an object is from you. This is perfect for navigating unfamiliar areas, inspecting spaces, or simply experimenting with LiDAR’s capabilities. Customize the app’s performance in the settings: Choose smoother, faster scanning, or prioritize visual quality for more detailed results. Please note: NightWalk operates within the effective LiDAR range of approximately 10 cm to 5 meters. Objects closer than 10 cm or farther than 5 meters may not be detected accurately. Whether you’re indoors, outdoors, or simply curious, NightWalk gives you a new way to experience the world around you.

Heightly is a focused height-measurement and 3D object-scanning app for LiDAR-equipped iPhones. Frame a complete person or object, tap the intended target, and hold the phone steady. Heightly combines LiDAR depth with the floor and nearby surfaces, then waits for multiple readings to agree before locking the height. Know exactly what you are measuring • Tap a visible target instead of measuring whatever happens to be largest • Use the highlighted outline, crosshair, and optional scan mesh as live feedback • Recognize supporting surfaces such as floors, tables, and seats • Freeze the camera when a result locks so the target and reading stay clear • View centimeters and feet/inches together 3D Object Scan • Capture an object from multiple angles • Build a textured USDZ model on your iPhone • Estimate model height from the finished main mesh while reducing sparse edge artifacts • Rotate, inspect, or share the completed 3D model Private history • Save frozen person or object snapshots with their measurement overlays • Keep completed 3D models with corrected height, width, and depth • Follow a child’s or family member’s height over time • Choose a history limit from 1 to 500 records • Delete one record or select several at once • Process and store camera frames, photos, depth data, and models on the device • No account required Requirements and measurement notes Live measurement and 3D scanning require a compatible LiDAR-equipped iPhone or iPad. Results can be affected by distance, lighting, reflective or transparent surfaces, occlusion, and scan coverage. Keep the full target visible and move the device slowly. Heightly is intended for everyday reference and is not a substitute for medical, engineering, construction, or other professional measurement.
