Experimentor vs Projectile Lab by ChatStick

Experimentor turns your iPhone into a powerful science data collection tool. With 16 built-in sensors, live charts, a customizable dashboard, web streaming, and AI-powered vision — it's the easiest way to run real experiments and learn about the world around you. COLLECT DATA FROM 16 SENSORS • Motion: Accelerometer, Gyroscope, Magnetometer, Gravity, Linear Acceleration, Rotation • Environment: Barometer (altitude & pressure), Location (GPS coordinates, speed, altitude), Sound Level (microphone), Light Level (camera) • Device: Battery, Screen Brightness, Proximity • Connectivity: Wi-Fi & Cellular signal strength • AI Vision: Object Detection and People Counter (powered by YOLO) REAL-TIME VISUALIZATION • Watch live charts update as you collect data • See min, max, average, and latest readings for every variable • Switch between sensors with a tap • Mark important moments during recording with markers STREAM TO ANY BROWSER • Turn on the built-in web server and open the URL on any Chromebook, laptop, or tablet • Scan the QR code or type the URL into Chrome — no app install needed • Live dashboard with sensor cards, sparkline charts, and a data table • Uses Server-Sent Events — works on any modern browser over your local Wi-Fi CUSTOMIZABLE DASHBOARD • Build your own live dashboard with 4 widget types: Gauge, Number, Bar, and Sparkline • Pick any sensor variable for each widget • Stream real-time data to all widgets at once • Rearrange and customize your layout FLEXIBLE UNITS • Tap any unit label to instantly convert (G-force ↔ m/s², radians ↔ degrees, kPa ↔ atm, and more) • 30+ unit conversions across acceleration, angles, distance, speed, pressure, temperature, and altitude EXPERIMENT TEMPLATES • 12 ready-to-go experiment templates for quick setup • Covers physics, environmental science, and everyday curiosity • Great for homework, science fairs, and classroom demos EXPORT YOUR DATA • Export to CSV for spreadsheets or JSON for code • Share results with classmates and teachers • All data is collected and stored on your device — nothing is ever uploaded CONTEXTUAL HELP EVERYWHERE • Every screen has a (?) info button explaining all buttons and features • Built-in walkthrough tour and complete help guide • Kid-friendly language and step-by-step instructions • No account required, no ads, no tracking Whether you're measuring the acceleration of a roller coaster, mapping sound levels around your school, streaming live data to a Chromebook, counting objects with AI, or tracking air pressure during a storm — Experimentor makes it easy, fun, and educational.

Projectile Lab is an interactive physics learning app that helps students understand projectile motion by doing, not memorizing. Build intuition with a real-time simulator, then deepen understanding with formula breakdowns, graph analysis, guided practice, and challenge levels. WHAT YOU CAN DO - Run live projectile simulations with adjustable angle, velocity, and launch height - Explore gravity environments including Earth and Moon (plus more with Premium) - View trajectory stats instantly: max height, range, flight time, and speed components - Learn the math with step-by-step formula sections and substituted values - Analyze motion with time-based graphs (height, distance, velocity, speed) - Practice with curated physics questions across multiple difficulty levels - Play challenge missions: hit targets, clear obstacles, land in zones, and maximize range - Save experiments to revisit and compare your best runs - Track progress through stars, streaks, and achievements DESIGNED FOR LEARNING Projectile Lab is built for students, self-learners, and educators who want a clean, focused environment for understanding motion. The app combines visual intuition and equation-level reasoning in one workflow. PREMIUM (ONE-TIME PURCHASE) - Removes ads - Unlocks all challenge content - Unlocks unlimited saved experiments - Unlocks all environments and advanced controls - Unlocks graph insights and full practice access No subscription required.
