The project is to build a cross-platform (iOS & Android) mobile application that calculates a car’s horsepower and torque in real time by fusing data from the phone’s accelerometer, gyroscope, GPS and any additional sensors required for true accuracy. Core flow • Capture live sensor streams at a high refresh rate, filter out noise, and apply the appropriate physics formulas to produce on-screen power and Nm readings with minimal latency. • Present the results in a modern, minimalistic interface that feels fluid and uncluttered. Smooth animations, dark/light themes and responsive layouts are essential. • Keep computation extremely fast; the math layer should be optimised (fixed-point or native code where necessary) so readings update instantly even on mid-range devices. Deliverables • UX mock-ups & final UI assets following current Material / Human Interface guidelines. • Well-documented source code for both platforms, including the sensor-fusion algorithms. • A test plan proving accuracy against at least two reference cars and covering edge cases such as strong GPS drift or sudden braking. • Build scripts or CI configuration enabling one-click release builds in the future. Acceptance criteria 1. Real-time power and torque refresh at ≥20 Hz with <5 % error compared to dyno data. 2. App cold-start to first reading in under 5 s on a recent mid-tier phone. Feel free to propose the tech stack—whether Flutter with platform channels for raw sensor access, React Native with native modules, or fully native Swift/Kotlin—so long as the precision and performance targets are met.
