Lightbox Tracing Pad vs Spectroscope

Turn your iPad or iPhone into a simple lightbox for tracing images on paper. Import a reference image, adjust it for clearer lines, lock the screen, place paper on top, and trace with a pencil or marker. Lightbox Tracing Pad is useful for sketch practice, lettering, craft patterns, tattoo idea outlines, illustrations, and kids learning to draw. Features: • Import images from your photo library • Adjust contrast and filters for clearer tracing • Pinch to resize and position your reference • Lock the screen to avoid accidental touches • Trace on real paper with your own pen or pencil No account. No data collection. Your images stay on your device. Lightbox Tracing Pad is a small, focused utility for turning a screen into a practical tracing surface.

Professional Spectral Analysis in Your Pocket Transform your smartphone into a powerful, calibrated optical spectrometer. Designed for science educators, researchers, and hobbyists, "Spectroscope" bridges the gap between educational tools and laboratory instrumentation. Connect a clip-on spectroscope hardware and start capturing, calibrating, and analyzing light spectra in real-time. NEW IN VERSION 2.0: • Reference Mode (REF): Perform comparative analysis seamlessly. Freeze a baseline spectrum (e.g., White Light) and compare it against live samples in real-time. Perfect for demonstrating Absorbance and Transmittance in the classroom without exporting data. • Multi-Camera Support: Fully optimized for modern devices. Select the specific lens (Telephoto, Ultra-Wide, Front/Back) that best fits your mounting setup directly from Settings. KEY FEATURES: • Precision Data Export: Generate scientific-grade CSV files with 4-decimal precision for both Wavelength (nm) and Intensity • Easy Calibration: Calibrate accurate X-axis (nanometers) using standard CFL lamps (Mercury peaks) or define your own custom reference points. • Live Analysis: Visualize data with the integrated high-contrast chart, featuring peak detection and adjustable exposure/focus locks. • Universal Compatibility: Works with any DIY or commercial spectroscope with a smartphone mount. APPLICATIONS: • Physics & Astronomy: Analyze emission lines of light sources and stars. • Chemistry Labs: Measure absorbance of colored solutions using the new REF workflow. • Gemology & Field Work: Portable analysis anywhere, anytime.
