Every trick here is broken into an ordered run of beats: the setup, the moment of misdirection, the move itself, the reveal, and the reset. Beside each beat two columns sit apart, one for what the audience is looking at, one for what your hands are actually doing. Nothing counts as learned until you put the beats back in order yourself and point to the exact instant the attention is pulled away. There are 48 tricks across six families, covering cards, coins, rope, mentalism, stage pieces and pure misdirection. The second half of the app exists to stop all of that from fading. Tap along to a target tempo and read your drift in milliseconds, rebuild a cue sequence against a countdown, or drag two handles around a ring of seats to mark the arc where the move would be visible. Practice away from the phone, come back, and log the attempt honestly as clean, flashed or dropped. All three carry the same credit, because what gets counted is turning up again. Confidence in a trick cools on its own, so the call board keeps reordering itself around whatever has gone quiet longest. Once a handful of tricks hold up, pin six of them into a running order and the reading will flag a repeated prop, two neighbours from the same family, or a pair of angles that fight each other. Everything stays on the device. No account, no ads, no network.

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. Our Boundaries - Does **not** provide meteorological data including typhoon tracks, wind speed or rainfall. Always refer to official warnings (permanent in-app reminder). - No account sign-up, no data upload. All data remains local and is deleted upon app uninstallation. Intended Users - People living in coastal typhoon-prone regions, especially those living independently for the first time - Users who want to create a simple, actionable typhoon preparation checklist for their parents - Those who want to prepare ahead each typhoon season but always miss key items Assessment results are for disaster preparedness reference only and shall not replace official disaster prevention guidelines and evacuation arrangements.
