Conversion vs Just Sensors

Type a number. Read the answer. That is the entire app. Conversion has been on the App Store since 2012. Version 4 is a complete rebuild — modern, quick, and still refreshingly free of clutter. BOTH UNITS, ALWAYS IN VIEW The two units face each other in the middle of the screen, right where you left them last time. Flick either one to change it, or tap an amount to turn the conversion around. Nothing to drill into. TWELVE CATEGORIES, 96 UNITS Length · Area · Volume · Weight · Temperature · Speed · Pressure · Power · Energy · Time · Computing — and Currency, with more than 160 world currencies. LIVE EXCHANGE RATES Rates refresh on their own and are stored on your device, so conversions still work on a plane or underground. When a rate is out of date the app says so, rather than quietly handing you an old number. YOUR LANGUAGE, YOUR NUMBERS 33 languages. Unit names, decimal separators and numbering systems all follow your region — so a comma lands where a comma belongs, and Arabic and Devanagari numerals are drawn properly. BUILT FOR iOS 26 Liquid Glass, a color for every category, fluid animation, haptics, and Dark Mode throughout. ACCESSIBLE FROM THE START Every control is labeled for VoiceOver. Text scales to the largest accessibility sizes. Reduce Motion is respected. A hardware keyboard drives the whole app. NOTHING COLLECTED No account, no ads, no analytics, no tracking. The app makes one kind of network request — for published exchange rates — and it carries nothing about you. Pay once. No subscription.

Just Sensors. Nothing more, nothing less. Your iPhone is packed with sophisticated sensors — accelerometers, gyroscopes, barometers, Bluetooth radios, and more — all working silently in the background. Just Sensors brings them to life with beautiful, real-time visualizations. ▸ EXPLORE 17 SENSORS Motion Sensors • Accelerometer — Interactive bubble level showing forces in real-time • Gyroscope — Watch rotation rates with smooth visualizations • Magnetometer — A digital compass with magnetic field strength • Barometer — Track atmospheric pressure and relative altitude • Device Motion — Visualize pitch, roll, and yaw with an animated 3D cube • Pedometer — Count steps, distance walked, and floors climbed Location • GPS — View coordinates, altitude, speed, and course on a live map Audio & Light • Microphone — Visualize sound levels with a live waveform and dB meter • Light Meter — Measure ambient light in lux using your camera AR Sensors (Pro devices) • LiDAR Scanner — Measure distances and visualize depth data • Face Tracking — See 52 facial blend shapes detected in real-time Device State • Proximity — Detect when objects are near the screen • Battery — Monitor charge level, state, and thermal condition • Orientation — See portrait, landscape, face-up, face-down • Brightness — Track display brightness levels • NFC — Read NFC tags and view their data • Bluetooth Scanner — Discover nearby BLE devices ▸ BLUETOOTH SCANNER • Discover nearby BLE devices in real-time • See signal strength (RSSI) for each device • Identify manufacturers using official Bluetooth SIG data • View advertised services and UUIDs • Switch between feet and meters for distance estimates ▸ SETTINGS & DEVICE INFO • Switch between US Standard and Metric units • View all app permissions at a glance • See detailed device information — model, memory, storage, screen specs • Quick access to iOS Settings to manage permissions ▸ BEAUTIFUL VISUALIZATIONS Every sensor gets its own tailored visualization: • Interactive bubble levels for motion data • An animated 3D cube for device orientation • A smooth compass dial for magnetic heading • Elegant gauges for pressure, light, and brightness • Live waveforms for audio • Device list for Bluetooth with signal strength • Depth views for LiDAR • Face mesh overlays for TrueDepth ▸ LIVE PREVIEWS See sensor data at a glance — the home screen shows live mini-previews for every sensor, so you know what's happening before you tap. ▸ RECORD & EXPORT Capture sensor data over time and export it for analysis: • Record sessions from any sensor • Export to CSV for spreadsheets • Export to JSON for developers • Share directly to Files, email, or other apps • Review and manage past recordings ▸ DESIGNED FOR EVERYONE Whether you're a developer debugging motion controls, a student learning about physics, a researcher collecting data, or just curious about your device — Just Sensors makes it easy. • Clean, dark interface with vibrant accent colors • Haptic feedback for a tactile experience • Choose your preferred measurement units • Works offline — no internet required • Privacy-focused — your data stays on your device ▸ SMART SENSOR HANDLING Just Sensors gracefully handles hardware differences: • LiDAR features require iPhone 12 Pro or later • Face tracking requires devices with Face ID • Sensors that need permission show tap-to-activate previews • Unavailable features are clearly indicated No fluff.
