Right now, the Sydney Opera House is greeting the morning. Right now, the Eiffel Tower in Paris is basking in noon light. Right now, the Statue of Liberty is drifting into dusk. Yonder Clock isn't a world clock. It's a window — showing you the world behind the time zones. Open the app, and you'll see a landmark somewhere on Earth in its real time of day: an Apple Maps 3D aerial view, slowly rotating. Every 15 minutes, the scene changes to another place experiencing morning, noon, or dusk. You don't have to do anything. Just watch. The world flows on its own. --- 500+ landmarks worldwide --- Across 35 cities — from the Sydney Opera House to the Sagrada Família, from the Golden Gate Bridge to Mount Fuji. Each landmark has a hand-tuned 3D aerial camera angle, crafted for that one perfect view. --- See it, collect it --- Every new landmark you see is automatically added to your collection. No effort required — just keep watching, and your world map fills in over time. Switch to the globe view to see how many cities you've "visited." --- Home screen widget --- Put the world on your home screen. The widget cycles through landmarks every 15 minutes, even if you don't open the app for a week. Morning somewhere, dusk somewhere else — a glance is all it takes. --- PRO --- • Unlimited shuffle — change landmarks whenever you want • Widget syncs with the app in real time • Freely browse all uncollected landmarks • Full access to 600+ landmarks in 3D Before you put your phone down, take one look. Somewhere in the world, the sun is just coming up.

Plumbline Studio
Read full descriptionHide full description
Plumbline Studio turns your iPhone into a focused measurement bench for carpenters, remodelers, inspectors, installers, and careful homeowners. Use it when you need a level, plumb check, protractor, slope calculator, flatness scan, or trade math without opening a pile of separate utilities. Core tools: - Live bubble level with tap-to-zero calibration - Dual-axis bullseye readout for cabinets, benches, shelves, and trim - AR-style plumb planning view for checking vertical alignment - Protractor and inclinometer with hold-to-lock angle capture - Slope calculator with rise, run, degrees, percent grade, and ratio - Stair, rafter, crown, board-foot, and cut-list helpers - Flatness scan for spotting dips and bumps across a surface - Project journal for saved measurements, notes, client names, and locations Plumbline Studio is built around practical job flow. Take a reading, lock it, copy it, save it to a project, and keep moving. The interface is designed for repeated work in a shop, basement, garage, or jobsite, not for a one-time novelty measurement. The app stores projects locally on your device. Camera and photo access are used only when you choose to attach a reference image to a measurement.
