ZenLevel turns your iPhone into a precision inclinometer with the calm, deliberate feel of a real machinist's instrument
ZenLevel turns your iPhone into a precision inclinometer with the calm, deliberate feel of a real machinist's instrument. Built for builders, DIYers, photographers, woodworkers, and anyone who needs something to be perfectly level, perfectly plumb, or precisely measured. FOUR MEASUREMENT MODES SURFACE — Lay your iPhone flat on a countertop, shelf, or picture frame. The two-axis bubble instrument shows the exact inclination, with individual digits that smoothly roll between values like a laboratory dial. When you find true level, the entire interface shifts to a calm, luminous green — the "zen moment" of perfect alignment. PLUMB — Press the back of your iPhone against any vertical surface to check if it's truly vertical. A tall bubble tube rises and falls based on how far the wall deviates from plumb. A "check hold" indicator warns you if your grip is too flat for an accurate reading. CALIBRATE — Every sensor drifts. Place your phone on a surface you trust to be flat, wait for the stability meter to reach 100%, and tap ZERO OUT. Your calibration offsets persist across app launches, so you only calibrate once. A separate "Reset calibration" action restores factory defaults at any time. HISTORY — Lock any measurement into an elegant log with automatic day grouping. Tap any entry to see full details, edit notes, or delete. Swipe-to-delete and Clear All are both available. LANDSCAPE PRECISION MODE Rotate your iPhone to landscape and SURFACE transforms into a long horizontal bubble vial, optimized for checking picture frames, shelf edges, and countertops along their length. A secondary "tipping" indicator helps you keep the phone vertical while measuring, preventing projection errors. The big degree readout rolls smoothly as you adjust, giving you real-time feedback. DESIGN THAT FEELS LIKE A REAL TOOL - Obsidian Laboratory aesthetic — deep blacks, subtle glass panels, signature zen green accent color - Rolling digit transitions on every measurement, tuned to 120ms per value change - Tactile haptic feedback on level reached, save success, calibration, and tab changes - Rotation-lock detection — if your phone is physically held sideways but iOS is locked to portrait, a banner guides you to enable rotation - Adaptive dark mode app icon - All measurements in degrees, accurate to 0.1° PRIVACY-FIRST, BY DESIGN ZenLevel is a single-player utility: - No accounts, no login, no cloud sync - No tracking, no analytics, no advertising - No network requests of any kind - All measurements and calibration data stay in your device's sandbox - No third-party SDKs WHO IT'S FOR - Carpenters and builders verifying walls, cabinets, and frames - DIY homeowners hanging shelves, pictures, TVs, and mirrors - Photographers checking tripod and subject alignment - Woodworkers verifying joinery and surface flatness - Industrial designers and engineers who want a phone tool that feels as precise as the real thing ZenLevel isn't a novelty. It's a precision instrument that lives in your pocket, ready to settle any question about "is this level?" in seconds.
