The most EFFECTIVE English Learning App ever developed! Nexgen has created a new class of learning app for the mobile platform—it delivers the same powerful AI content used in courses taught at top schools, governments, and businesses around the world. neoStudy’s AI adapts and curates content to improve your learning outcomes by continuously giving you more of what you need and less of what you already know until you reach mastery. A single app with cloud-based content, available in 11 certification skill levels. Levels are based on the Common European Framework of Reference for Languages (CEFR+ levels): Pre-A1, A1, A1+, A2, A2+, B1, B1+, B2, B2+, and C1. Courses are available for ages 4–Adult. A bonus level for higher level spoken communications, C1-Bridge, is also available. With neo, you can achieve your CEFR level goal in approximately three months per level. Simply focus on earning 6,000 study points per week to get these results. Earn more points per week and reach your goals faster; earn less and it will take a little longer You will pass verification tests along the way and attend bi-weekly online coaching sessions with an approved coaching provider.
NL Sensor

NL Sensor turns your iPhone or iPad into a live dashboard for Nu Lambda Scientific Bluetooth sensors. Connect a sensor, watch the data stream in real time, analyze it on the spot, and export it — all on device, with nothing sent to the cloud. MEASURE ANY SENSOR IN THE FLEET • Motion / distance, force / load, voltage, current, pressure, illuminance, 3-axis magnetometers, dual-thermistor temperature probes, and photogates are detected automatically by name. • Metric cards show the current value and a stable 40-point average. • Set the sample rate from 1 to 100 Hz right from the app. LIVE CHARTS BUILT FOR THE LAB • A smooth 10-second sliding window while you measure. • Pause to pan and pinch-zoom — each axis zooms independently, so you can stretch time or values on their own — then show all data, reset, or clear. • Drag to select a region and get a least-squares linear fit (slope, intercept, R²) or statistics (mean, standard deviation, count). • Expand any chart to full screen. MOTION, VELOCITY & ACCELERATION • Motion sensors add derived velocity (m/s) and acceleration (m/s²) charts, computed with smoothed derivatives. PRESSURE & TEMPERATURE • Pressure sensors add a Temperature-vs-Time chart and a Pressure-vs-Temperature graph, with a fine ±0.1 hPa scale for reading small changes. DUAL TEMPERATURE • Dual-thermistor probes show T₁ and T₂ together on one chart plus a separate chart for each, colour-coded red and green. PHOTOGATE EXPERIMENTS • A photogate sensor turns beam-block timing into seven ready-made experiments: Basic Free Fall, Single Gate, Two-Gate Timer, Pendulum Period, Speed (two-stripe card), Pulley, and Two Gates. • Get distance–time and speed–time graphs, oscillation periods with average and spread, angular motion from a pulley, and precise gate timing — then linear-fit a speed–time graph to read acceleration straight off the slope. WALK THE GRAPH • Turn distance-time graphs into a movement challenge: pick a target curve, walk to match it, and get a live score for how well your motion tracks the graph. Five graph sets from basic to creative. TWO SENSORS AT ONCE • Connect two sensors and compare them on an XY chart that pairs their latest readings in real time. • Pause the XY chart to pan, pinch-zoom, drag-select a range for a linear fit or statistics, and tap any point to read its A / B values. TONE GENERATOR (NO SENSOR NEEDED) • A built-in signal generator, open straight from the dashboard. Play a pure sine tone from 0.5 Hz to 20,000 Hz with a slider, exact numeric entry, and a fine/coarse adjust pad. • Run a frequency sweep (chirp) with your own start, final, step size and step duration, and a live progress bar — great for hearing tests, resonance hunts, and Doppler demos. • Switch to Dual Tone to sound two independent tones at once for beats, musical intervals, superposition, and masking. Set amplitude and output channel (both, left, or right) for each tone. EXPORT EVERYTHING • Export any chart, the XY data, or the entire session as CSV through the iOS share sheet. PRIVACY • All measurements stay on your device. No account, no tracking, no data collection. NL Sensor requires a compatible Nu Lambda Scientific Bluetooth sensor. A built-in demo mode lets you explore the app without hardware.

Verdict
The clearest difference is update cadence: NL Sensor at every 2 weeks against neoStudy's every 2 months. neoStudy's advantage is iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
