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.

Verdict
The clearest difference is rating: ZenLevel at 5.0 against IIDControl's 3.9. IIDControl's advantage is ratings volume (14 vs 1) and update cadence (every 2 months vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.
