NightWalk Depth Scanner vs Rosettica

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.

Rosettica is a privacy-first AI translation app for iPhone, iPad, and Mac. Translate text into multiple languages at once with TranslateGemma running on-device, stream results in real time, and keep your data off third-party servers. Powered by TranslateGemma 4B on Apple's MLX framework, Rosettica runs fully on-device for maximum privacy. You can also connect to your own OpenAI-compatible server, or let your iPhone use your Mac as a local translation server over Wi-Fi. KEY FEATURES: • On-Device AI Translation — Run TranslateGemma locally on Apple Silicon. After a one-time model download, translation works entirely offline with no cloud APIs. • Local Network Translation (Mac + iPhone) — Turn your Mac into a translation server for nearby iOS devices. Your iPhone discovers the Mac automatically via Bonjour on the same Wi-Fi network and offloads translation to the Mac's more powerful hardware. All traffic stays on your local network. • Multi-Target Translation — Translate to multiple target languages simultaneously. Each language gets its own live-updating card with real-time streaming output. • Automatic Source Language Detection — Rosettica detects the source language automatically using on-device NaturalLanguage analysis. You can also override the detected language manually. • 55+ Language Coverage — Built on TranslateGemma, benchmarked across 55 core languages including Chinese, Japanese, Korean, Arabic, Spanish, French, German, Hindi, and more. • Image-to-Text Input (OCR) — Extract text from photos, camera captures (iOS), or imported image files (Mac), then translate it instantly. • Flexible Backends — Switch between on-device, remote server, or local network modes in Settings. • Multiple Remote Endpoints — Configure and prioritize multiple OpenAI-compatible endpoints (LMStudio, vLLM, Ollama, etc.) with connection testing, model discovery, and drag-and-drop reordering. • Performance Controls — Tune max parallel translation tasks to balance speed and memory usage for your hardware. No upper limit — you decide based on your device. • Translation History + Search — Every translation is saved locally. Browse, search, and copy past results anytime. • iCloud Backup & Restore — Back up and restore your translation history using your own iCloud account. • Privacy First — No analytics SDKs, no tracking, no account required. Your translations stay on your devices. Rosettica is free with an optional tip jar. Built for people who need fast multilingual workflows while staying in control of where their data is processed.
