> Detect Invisible Fields: Find the ElectroMagnetic Fields around you in seconds > Pro-Grade Precision: High-accuracy Magnetic Field Analyzer & Gauss Meter with Advanced Signal Stabilization. > Record, Analyze & Export: track trends with interactive data charts and save detailed logs for professional analysis. Check out the areas where you work (desk, meeting rooms), where you sleep (bed), where you relax (couch, living room) and find the levels of EMF you are exposed to. Also use the app to measure the fields emitted by your appliances (computer, fridge, speaker, phone...). PROFESSIONAL MAGNETIC FIELD ANALYZER & GAUSS METER: Discover the invisible magnetic world around you. Using your device’s internal magnetometer, the app provides a comprehensive look at the electromagnetic fields (ELF) generated by electronic devices, wiring, and ferromagnetic materials. NEW PROFESSIONAL FEATURES: - 3-Axis Vector Analysis: Real-time $x, y,$ and $z$ coordinate tracking for precise field directionality. - Interactive History Graphs: Visualize time evolution with high-resolution charts that track spikes and trends. - Clean Signal Mode (LPF): Toggle an advanced Low-Pass Filter to stabilize readings and remove sensor jitter for professional-grade clarity - Save & Export Logs: Record your sessions and export data for further analysis in external software. VERSATILE USE CASES: Electronics Inspection: Measure the magnetic footprint of computers, speakers, and home appliances. Metal Detection: Locate ferromagnetic objects like iron pipes or steel studs behind walls. Interference Calibration: Find the "quietest" zones for sensitive electronic equipment or audio setups. USER EXPECTATIONS & DISCLOSURE: This app is designed as a sophisticated utility for detecting Magnetic Fields (ELF). What it detects: Magnetic flux from magnets, ferrous metals, and the low-frequency electromagnetic fields emitted by electronic components, power supplies, and speakers. What it does NOT detect: This app is not a radio frequency (RF) scanner. It cannot detect Wi-Fi signals, Bluetooth, 5G cellular radiation, or microwave leakage. DISCLAIMER: - This app is intended for educational and utility purposes. It is not a substitute for certified industrial or scientific equipment. It does not provide medical advice or guarantee "safe zones" in a clinical sense. This app does not guarantee exact measures as other fields can interfere with the compass inside your phone, which is used to detect the fields.

One place to move a card? Tap once and it goes. Several places? See what each one changes before you choose. Check whether a face-down card will open or stay hidden, make the move yourself, then use Undo to try a different path. Klondike for a quiet break at a bright terrazzo table. See the effect, then choose - When a card has several destinations, each foundation and column shows its immediate effect: one face-down card opens, a column becomes empty, one card goes to a foundation, or face-down cards stay unchanged. Only what will actually happen is shown. - The app does not pick the best move for you and never reveals face-down cards. The choice is yours. - Turn on Always choose a destination in Settings to preview the effect even when there is only one destination. Try again - Undo with no limit, back to the start of the game. Your history is kept when you close and reopen the app. - Hints show one legal move and why it is legal. A hint is not a promise that you will win. - When no card can move, the app points to drawing, recycling the deck, Undo or a new game. It never declares a deal unwinnable. - Auto-complete runs only when you tap it, and only after every card is face up, the deck and waste are empty, and a full foundation sequence has been verified. Your game, kept quietly - Draw one or draw three, with unlimited deck recycling - Games are saved so you can continue later - Win rate, average moves, best time, best score, daily win streaks and 12 badges - Share your records only when you choose to - No ads, no account, no tracking. Records stay on this device. - English and Korean, light and dark mode, large text, VoiceOver, and a card list for choosing cards Good to know - Deals are random and some may not be winnable. - Undo is unavailable after a game is completed. - Scores are for personal play and are not compared with other players. - Your previous wins, losses and abandoned games, times and badges are kept. The previous version did not save games in progress, so those games cannot be restored. New times measure active play.
