Spectroscope vs Ranked Choice

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.

Stop arguing about where to eat. Ranked Choice: Group Vote lets any group make fair, decisive decisions using instant-runoff voting — a proven, fair voting method trusted by groups everywhere. Create a vote, share a 5-character code, and everyone ranks their preferences. The app eliminates options round by round until a clear majority winner emerges. No tie-breaking arguments. No "I guess we'll just do whatever." A real winner, every time. **Split a group across several options:** Some decisions are not about one winner — they are about who goes where. Give each option a size, and Ranked Choice divides everyone into groups, keeping each person as high up their own ranking as it can: • Carpools — riders into cars by seat count • Classrooms — students onto project topics or lab benches with caps • Conferences and workshops — attendees into breakout rooms • Work offsites — staff across team-building activities • Volunteer shifts — a minimum and maximum per slot • Restaurants — a large party across tables • Hackathons — people onto projects with team-size rules • Sports — pickup teams, courts and tee times • Summer camps, seminars, small groups, hotel rooms, bunks Pick "best overall" or "no one left out", and give an option the size it works best at when it has one. **Everyone adds their own options:** Collect ideas from the whole group first — three each — then vote on what came in. **Pass the phone:** Not everyone in the room has the app. The host enters ballots on one device, one person at a time, and the results show which votes came in that way. **Works anywhere your group is:** Vote together in the same room over Bluetooth and Wi-Fi, or host votes over the internet with a join code or QR scan — no accounts required for anyone. **Instant-runoff voting, the right way:** Voters drag options into their preferred order. The engine eliminates the least-popular choice each round, redistributing votes until one option has a majority. Live results update as votes arrive, with a full round-by-round breakdown when voting closes. **Everything you need:** • Cloud voting over the internet — share a 5-char code or QR • Local voting over Bluetooth/Wi-Fi — no internet needed • Set a deadline with a live countdown timer • Anonymous mode hides voter names from results • Allow or lock vote changes after submitting • CSV import for bulk option entry • Results export as a shareable image • Deep link support: rankedchoice://join/CODE • Deadline notifications — 5 min warning + close alert No sign-up. No accounts. No tracking. Just fair group decisions.
