Turn motion into insight. 让现实世界的运动成为洞见。
Accelio transforms your iPhone into a portable 3-axis motion data logger. Observe real-time waveforms like an oscilloscope, record lossless binary streams like a black box, inspect FFT/STFT spectra, and export raw measurements anytime. Accelio 将你的 iPhone 转变为便携式三轴运动数据记录仪。像示波器一样实时观察振动与轨迹小球，像黑匣子一样可靠记录原始测量流，内置滤波与频谱分析工作台，随时无损导出原始数据。
Professional Core, Friendly Experience专业测量内核，直觉友好体验
Built from the ground up in Swift 6 with a strictly decoupled serial acquisition engine, Accelerate vDSP signal processing, and zero third-party SDKs. 基于 Swift 6 原生构建，底层传感器采集与界面渲染彻底解耦，集成 Accelerate vDSP 确定性信号处理，零第三方追踪依赖。
3-Axis Live Scope & Trajectory Ball三轴实时示波与轨迹小球
Monitor X, Y, Z readings in g or m/s², watch the 2D trajectory ball with auto-ranging rings, and freeze live waveforms without interrupting background capture.以 g 或 m/s² 观察三轴等宽读数与带渐隐拖影的二维加速度小球；支持冻结显示，绝不阻塞底层样本写入。
Crash-Safe Chunked Recording防崩溃分块二进制录制
Every chunk carries a CRC-32 checksum. Foreground interruptions are recorded honestly as explicit time gaps, and interrupted sessions are salvaged automatically on launch.采用带 CRC-32 校验的小端分块流落盘；前后台切换如实记录为空洞，意外终止后重启即可自动恢复已提交数据块。
Millisecond Envelope Timeline毫秒级多分辨率时间线
Min/max envelope pyramids preserve single-sample impacts across multi-hour overviews. Pinch to individual sample dots, drag dual cursors, add markers, and extract sub-sessions.Min/Max 包络金字塔确保单样本冲击峰值在长时概览中永不丢失；支持捏合到单点、双游标截取、打标与提取子记录。
FFT, Welch PSD, STFT & FiltersFFT / PSD / STFT 与零相位滤波
Gap-aware uniform resampling feeds zero-phase 2nd-order Butterworth low/high-pass filters, Hann FFT amplitude spectra, Welch PSD, STFT heatmaps, and world-frame attitude rotation.跨空洞分段均匀重采样，驱动双向零相位 Butterworth 高低通滤波、Hann 窗 FFT、Welch PSD、STFT 时频图与世界坐标系变换。
Honest Sensor Diagnostics诚实硬件采样率诊断
Requested sample rates are never taken on faith. Built-in Sensor Diagnostics and per-session Quality Reports compute achieved rate, median interval, and jitter from hardware timestamps.不轻信标称频率。内置「传感器诊断」与单次记录采样质量报告，依据硬件真实时间戳统计有效采样率、间隔中位数与抖动。
Grounded BYOK AI Workbench可溯源 BYOK 智能分析
Optional Ask Accelio & AI Chart Builder store your API key in iOS Keychain, never upload raw time series, and verify every cited number against 8 deterministic local tools.可选「问问 Accelio」将自带密钥仅存于系统钥匙串，绝不上传原始时间序列，所有数值均通过 8 个本地确定性工具溯源校验。
Your Data Belongs to You开放数据格式，数据完全归你所有
Export full sessions or millisecond selections directly into Python, MATLAB, Excel, or lossless `.accelio` archives with unit-explicit English headers and traceable metadata. 随时将整段记录或选区导出至 Python、MATLAB、Excel，或打包为无损 `.accelio` 原生归档包，表头自带物理单位与完整溯源元数据。
