Lervath

Lervath — Typhoon Pre-Prediction & Preparation Tool Once a typhoon warning is issued, panic often sets in: forgetting to clear balconies, failing to reinforce doors and windows, scrambling to gather supplies, and being caught off guard by power outages. Lervath focuses on the window of time **before a typhoon arrives**, helping you systematically complete home risk self-inspection and advance preparations. Core Features Home Profile Record housing type, floor level, windows, balconies, surrounding environment and past power outage experiences as baseline parameters for risk prediction. All data is stored locally on your device only. Hazard Identification Self-Check An automatically adapted hazard checklist generated based on your home profile. High-rise residents will see hazards related to exterior wall brackets; bungalow users will see roof-related hazards. Tick the hazards present in your home. The app locally calculates an overall risk score and outputs a four-tier risk report: Low / Medium / High / Extreme. Risk Prediction Report A dashboard displays the composite risk score and risk level, summarizing every identified hazard. It gives general recommendations on how many days in advance preparations should start, with one-tap access to corresponding preparation tasks and supply lists. Advance Preparation Task Checklist To-dos are split into four phases: **3 days in advance / 2 days in advance / 1 day in advance / On the day of warning**. Tasks include balcony clearance, weatherstripping inspection, cross-taping window glass, evacuation route planning, and more. Higher risk levels unlock a more complete task list. Supports custom tasks, checkmark completion, reset, and text export (copy to clipboard). Emergency Supply Inventory Categorized supply lists for lighting & power, drinking water & food, first aid & protection, reinforcement tools, communications, with recommended quantities and notes (e.g., 2L drinking water per person per day). Higher risk levels add more recommended supplies; for example, high-risk scenarios include waterproof pouches, first aid kits and spare batteries. Custom supplies can be reused across reports. Emergency Response Handbook Six emergency scenarios: falling objects from height, water seepage through doors/windows, prolonged power outages, broken glass, standing water nearby, and being trapped indoors. Contains prohibited actions, response procedures and preventive tips for each scenario. Supports local search and one-tap navigation, with built-in emergency phone numbers (tap to trigger system dialing). Historical Self-Inspection Records Each self-inspection is automatically saved. You may review reports and update task and supply progress anytime. Duplicate self-inspections with identical content will be flagged to avoid bloated, redundant records.
