## ZenLevel Description
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 perfectly level, perfectly plumb, or at exactly the right slope.

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 digits that roll smoothly between values like a laboratory dial. When you find true level, the interface shifts to a calm, luminous green.

PLUMB — Press the back of your iPhone against a vertical surface to check whether it is truly vertical. A tall bubble tube rises and falls with the wall's deviation, and a "check position" warning tells you when the phone is too flat for an accurate reading.

CALIBRATE — Every sensor drifts. Place your phone on a surface you trust, wait for the stability meter, and tap ZERO OUT. Offsets persist across launches, and Reset calibration restores factory defaults at any time.

HISTORY — Save any measurement to a log grouped by day. Tap an entry to see its details, edit its note, or delete it.

HOLD THE READING

Measuring under a shelf or behind a cabinet? Tap HOLD to freeze the reading, then take your iPhone out and read it — or save it — at your leisure. Tap RELEASE to go live again.

SLOPE UNITS

Show every reading in degrees, percent grade, millimetres per metre, or inches per foot. Rise-over-run units make drains, ramps, patios, decks, and gutters easy: a quarter inch per foot is simply 0.25 in/ft. Saved measurements follow your chosen unit and keep the original angle alongside.

LANDSCAPE PRECISION MODE

Rotate your iPhone to landscape and SURFACE becomes a long horizontal bubble vial for checking frames, shelf edges, and countertops along their length. A tipping indicator helps you keep the phone upright to avoid projection errors.

DESIGN THAT FEELS LIKE A REAL TOOL

• Deep blacks, subtle glass panels, and a signature zen-green accent
• Rolling digit transitions on every live readout
• Haptic feedback on level, save, calibration, and tab changes
• Rotation-lock detection that guides you when iOS is locked to portrait
• Decorative animations pause when Reduce Motion is on

PRIVACY FIRST, BY DESIGN

• No accounts, no login, no cloud sync
• No tracking, no analytics, no advertising
• No network requests of any kind
• Measurements and calibration stay on your device
• No third-party SDKs

WHO IT'S FOR

• Carpenters and builders checking walls, cabinets, and frames
• Plumbers and landscapers setting drain and patio falls
• DIY homeowners hanging shelves, pictures, TVs, and mirrors
• Photographers aligning tripods and subjects
• Woodworkers checking joinery and surfaces

ZenLevel isn't a novelty. It's a precision instrument that lives in your pocket, ready to settle "is this level?" in seconds.
