Put your HTML text here<p><b>EUC SoH</b> is a state-of-health (SoH) analysis tool for electric unicycles. It processes ride logs from popular EUC logging apps to estimate battery health, internal resistance, and long-term degradation patterns.</p> <p>The app runs entirely on-device, without trackers or network access. It is fully free and open source under the AGPL license.</p> <p><b>Main features:</b></p> <ul> <li>Scan storage recursively to discover WheelLog and EUC World subfolders and CSV log files automatically (optional support for DarknessBot dumps).</li> <li>Parse ride logs and separate accepted files from rejected ones, with explicit rejection reasons (e.g. too few data points, invalid Req computation).</li> <li>Compute state-of-health metrics such as equivalent resistance (Req) and CUSUM-based indicators.</li> <li>Display interactive charts (MPAndroidChart) to visualize resistance evolution and SoH trends over time.</li> <li>Maintain per-wheel file management: inspect logs per wheel, exclude problematic files, and keep a clean dataset.</li> <li>Export a structured archive for resale, expertise, or maintenance: PDF report (soh.pdf), statistics CSV, and associated logs organized by wheel identifier.</li> <li>Share generated PDF and archives directly via messaging apps, email, or cloud storage.</li> <li>Work fully offline: no account, no registration, no external server.</li> </ul> <p><b>Typical workflow:</b></p> <p><b>A - Your own wheel</b></p> <ul> <li>Record rides using WheelLog, EUC World, or DarknessBot.</li> <li>The app scans storage for folders containing compatible logs.</li> <li>If using DarknessBot: export a dump (.dbb) and enable .dbb search in the app.</li> </ul> <p><b>B - Purchased wheel with EUC SoH archive</b></p> <ul> <li>Import the archive into the app.</li> </ul> <p><b>Start analysis</b></p> <ul> <li>Scan subfolders recursively to find compatible CSV files and group them by wheel.</li> <li>Run SoH analysis to compute Req and related m
