The AptixAR Infinity platform connects your remote workforce and experts using on-demand digital twins. Your team can collaborate in both real-time and asynchronously. This isn't just a tool for marking up video calls: AptixAR brings your expertise into the field without ever leaving the office. The iOS app is used by remote workers to connect to experts, and by experts to build out assets in the field. Users can accept and initiate video calls augmented by experts in 3d space, in real time or asynchronously. Users can capture photos, chat with experts, and perform assembly, inspection, maintenance, repair, calibration, or any other task. AptixAR Infinity requires an iOS device that support LiDAR depth sensing, such as the iPhone 12 Pro, iPhone 12 Pro Max, iPad Pro 11-inch (2nd generation), iPad Pro 12.9-inch (4th generation) or successor devices.

Measure light properly — in lux, foot-candles, EV, or PPFD for plants — using your iPhone's camera to read the light falling on the scene. GROW LIGHTS & PLANTS • PPFD estimated from your live reading, matched to your light source: white LED, HPS, fluorescent or daylight • DLI for a 12, 14, 16 or 18 hour photoperiod, so you can tell whether a shelf actually reaches a seedling's daily light target • These are spectrum-based estimates, not a calibrated PAR sensor. Read them as guidance for placing lights, not as lab data. FOUR MEASURING MODES • Auto — radial gauge with the closest real-world reference shown live • Outdoor — a log scale to 100,000 lx, from deep twilight through overcast and direct sun • Indoor — 10 to 10,000 lx, from corridor and living room up to reading desk, drafting and surgical levels • Photo — EV at ISO 100 with a suggested shutter speed HISTORY THAT ADDS UP • Every reading saves automatically, with a 7-day trend chart and plain-language insight such as "+12% vs your 7-day average" • Notes and favourites — label a reading "kitchen window 3pm" and star it • Compare any two saved readings side by side • Export everything as CSV, or share a single reading as an image MEASUREMENT DETAIL • Kalman-smoothed readings, so there is no jitter to read through • Min, max and average with elapsed time • Log-scale range bar in Outdoor and Indoor modes • Lux, foot-candle and EV units • Calibration factor — scale every reading by a multiplier to match a reference meter you trust WHO USES IT Indoor gardeners and grow-tent owners · photographers and filmmakers · electricians and lighting installers · studio engineers · workplace and office ergonomics checks · industrial lighting surveys HOW IT WORKS Readings are estimated from the back camera's exposure, so this is a reflected-light measurement: point the back of the phone at the surface you care about and keep the lens clean and unshaded. Because it reads reflected light, a white wall and a dark carpet under identical lighting will not read the same, and very dim scenes are the least reliable. Cameras differ between models, so for absolute numbers set the calibration factor against a meter you trust. Available in 25 languages.
