Store description excerpt
Level Dot turns your phone into a precision spirit level — clean, fast, and unobtrusive. Designed after the level apps that pros actually keep on their home screen (Apple Measure, iHandy Level, Clinometer), but without the ads on top of your measurement, the usage caps, or the cluttered toolbox UI. KEY FEATURES • 2D bubble level for face-up surfaces, 1D edge level when held vertical, with automatic mode switching based on how you hold the device. • Three units: degrees (°), percent grade (%), and millimeters per meter (mm/m). • Calibrate any reference surface to 0° with one tap. Long-press to reset. • Hold/freeze the reading while you read it. • Haptic + audible "level" feedback at 0°, with a Schmitt-trigger hysteresis so it does not chatter. • Dark, Light, and Material You dynamic themes. • Edge-to-edge fullscreen. Screen stays on while measuring. • English and Korean (한국어) UI. • Automatic update prompt when a new version is available. ACCURATE BY DEFAULT Built on Android's TYPE_ROTATION_VECTOR sensor with a tuned low-pass filter, automatic screen-rotation correction to the display frame, and a tight Schmitt trigger on the "level" indicator. No fake skeuomorphic noise — just the number you came for. NO PAYWALLS, NO INTERSTITIALS A discreet bottom banner is the only ad. We never put advertising on top of the measurement area, never gate features behind paid tiers, and never time-limit your free usage. Calibrate as much as you want. PRIVACY The app does not collect personal data. The only network usage is the bottom banner served by Google AdMob under Google's standard advertising policies. WHO IT IS FOR Carpenters and DIYers leveling shelves, frames, and appliances. Photographers leveling tripods. Roofers checking pitch. Anyone who just wants to know whether that table is actually flat. REQUIREMENTS • Android 8.0 (Oreo) or later • Accelerometer (standard on all modern phones) • Optional gyroscope for slightly better stillness detection
