Twindo vs Frequency Generator & Analyzer

The offline-first field service app for any asset. Twindo gives field technicians everything they need on site: inspection reports, task management, timesheets, live project overviews and an AI copilot that works without signal. From wind turbines and solar parks to substations, battery storage and industrial equipment, Twindo works for any asset you inspect and maintain. On iPhone and iPad. WORKS OFFLINE, EVERYWHERE Offshore, up a tower, in a remote solar park or deep inside a plant, Twindo keeps working. Capture reports, log hours and look up procedures with no connection. Everything syncs automatically when you're back online. OFFLINE AI COPILOT Your expert in the field, even without signal. Ask about repair procedures, quality checks and technical limits, and get clear, step-by-step answers right at the asset. ANY ASSET, ONE APP Twindo is asset-agnostic. Set up your work the way your operation runs: - Organise everything by project, site, asset and sub-asset - Wind (onshore and offshore), solar, hydropower, grid and substations, battery energy storage, industrial plants and more - Go from a whole site down to a single component, like a bearing or a seal INSPECTION REPORTS FROM THE ASSET - Start a report in seconds by picking the project, site, asset and sub-asset - Add photos that are automatically stamped with time and GPS location - Rate condition from Excellent to Critical and add comments and notes - Save drafts and submit when you're ready, with status tracking from draft to complete PROJECTS AND TASKS AT A GLANCE - See completion, tasks, reports and alerts for every project - Keep track of jobs and tasks across multiple sites - Live weather maps with wind forecasts for each site TIMESHEETS IN SECONDS - Log working time, travel, breaks, meetings and weather standby - See your day at a glance with an automatic hours breakdown - Add your crew, per diem, on-call time, HSEQ reporting, and consumables and equipment - Sign digitally and submit straight from the field SCHEDULING AND NOTIFICATIONS - See every job and every day in one schedule - Get notified when work is assigned, updated or needs review BUILT BY PEOPLE, FOR PEOPLE IN THE FIELD Twindo is built with technicians, not just for them.

Live Oscilloscope Grid: Visualize active sound waves on a sweeping, highly responsive neon coordinate grid. Signal Gain Adjuster: Amplify low-amplitude ambient sounds easily by adjusting the visual height of the oscilloscope lines. Music Note Translator: Automatically convert active frequency measurements to the closest corresponding musical note (based on standard A4 = 440 Hz tuning). 2. ADVANCED STATS & ANALYTICS (PRO) Live Session Tracker: Monitor Minimum, Maximum, and Average frequencies detected during your active scanning session. Integrated Decibel Meter: View current volume levels (dB) directly alongside your frequency readout. RPM Speed Calculator: Measure the speeds of rotating fans, propellers, or motors with a configurable blade multiplier (1 to 8 blades). 3. PRECISION SCAN CONTROLS Freeze Screen: Freeze the active frequency readout and grid at any moment to inspect specific sound intervals. Reset Peak Meter: Instantly clear out the highest recorded peak frequency with a single tap. Start/Stop Engine: Complete control over your microphone input scanning sessions. 4. PROCEDURAL SOUND WAVE GENERATOR (PRO) Real-Time Sound Synthesis: Generate continuous tones supporting four reference waveforms: Sine (Cyan), Square (Green), Sawtooth (Orange), and Triangle (Purple). Tactile Tuning Pad: Fine-tune your output with incremental coarse buttons (-100, -10, -1, +1, +10, +100 Hz). Interactive Sweepers: Seamlessly navigate the human hearing spectrum (20 Hz - 20 kHz) using linear volume and logarithmic sweep sliders. Direct Hz Keyboard: Double-tap the main Hertz indicator to type your exact desired frequency via a dedicated number pad.
