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.

Your Home Screen, finally quiet. Clearwing is a collection of 21 widgets that look truly transparent: clocks, calendars, countdowns, a moon phase, a photo, floating on your wallpaper with nothing around them. And the part nobody else fixed: there is no app name under them. iOS prints the app's name beneath every widget, which ruins the clean look unless you switch to large icons. Clearwing's own name is invisible, so its widgets carry no label and you keep your small icons. 21 WIDGETS • Invisible spacer: pure wallpaper, for airy layouts • Clocks: digital, a minimal analog dial, a word clock that says half past nine, and a binary clock in glowing bits • Day & Time: the date and the clock in one glance • Date, Weekday written large, and a monthly Calendar with today circled • This Week strip and the week number • Countdown with a progress ring, and Days Since for streaks and anniversaries • Year Progress, Day Progress, and a Year Grid with one dot for every day • Moon: tonight's phase, computed on your device • Daily line: one calm sentence a day • Photo in a floating frame, arch, circle, or tilted polaroid • Monogram with your initials • Battery in a glowing ring FIFTEEN LOOKS FOR EVERY WIDGET Retro Pixel is the signature default, and every widget also comes in Minimal, Editorial serif, Bold, frosted Glass, Handwritten, Script calligraphy, Typewriter, Neon, Couture fashion serif, Engraved, Chalk, Marker, Retro geometric, and Poster. Browse the whole collection in the built-in gallery, rendered live on your own wallpaper, then pick looks and tones per widget. A frosted-glass backdrop option gives you the soft blurred-wallpaper card style too. SET UP IN A MINUTE iOS does not allow real see-through widgets, so Clearwing recreates your wallpaper behind each one, pixel for pixel. Take one screenshot of an empty Home Screen page, import it, and place your widgets. A built-in fine-tune editor nudges the alignment if your device sits a pixel off, and switching between small and large icon modes is one tap. WRITTEN ON YOUR IPHONE On iPhones with Apple Intelligence, the Daily Line widget writes a fresh calm line every day, entirely on-device. Without it, a curated pack takes over seamlessly. PRIVATE BY ARCHITECTURE • Clearwing contains zero networking code, so nothing can leave your iPhone • No account, no ads, no analytics, no tracking • Your wallpaper and photos stay in the app's private container • Delete the app and every trace is gone Free. No subscription. No catch. Your wallpaper deserves the whole screen.
