Surface Time vs PD Meter

Timer apps are usually always simple with few buttons, but Surface takes this simplicity to the next level. With no buttons, taps, or swipes, the timer just turns on and off. It is designed to intuitively encourage you to put your phone down. The timer values peek from a small circle, and as you move your iPhone across angles, the circle expands with subtle haptics, nudging you to keep going and rest your phone on the surface facing down. The hidden yet visible options for Settings and Goals are not only designed to prevent opening when you might accidentally touch or swipe when flipping your phone, but are also intentionally uninviting for you to interact. However, the moment you choose to do interact, it transforms itself into a beautiful control. A control that encourages you to make a gesture and intentionally reveal the hidden features. The app is mainly aimed to help you stay focused in your work while keeping your phone at arms reach. But it is truly versatile, and I personally found myself using this everywhere. For instance in the kitchen, when my hands are dirty and I don't want to touch the screen or shout at my voice assistants, or to monitor my workouts with intervals. I'm sure there are many more ways to use this! For basic timer features, you'll never have to touch the screen or press any buttons. Just flip your iPhone back up to reveal the screen and the timer pauses. Then, you can shake to reset or flip back down to resume. Notifications: Surface uses backside LED flash to signal when timer begins. You can also set periodic notifications using LED flash or using calming sounds, such as of Himalayan Bowl or Guitar Strum to keep rough track of duration without looking at your timer. Goals: By default, your surface time per day is always saved and visible from the Goals view. You can adjust this goal to whatever duration you want. Plus, you can create custom everyday color-coded goals for different tasks and monitor your everyday progress.

Ordering glasses online and need your PD? PD Meter helps you measure your pupillary distance (PD) in millimeters using a front-camera selfie and any standard-size card, like a credit card, for scale — no ruler, no second person, no trip to the optician. Your pupillary distance is the gap between the centers of your pupils. Online eyewear stores ask for it so your lenses are centered correctly in the frame. PD Meter gives you a quick, repeatable estimate from the comfort of your home. HOW IT WORKS • Hold a standard card (a credit card, ID or any ISO-size card) under your eyes — its known width gives the app a real-world scale. • Take a front-camera selfie, looking straight at the lens. • Mark the center of each pupil and the edges of the card. • PD Meter converts pixels to millimeters and shows your PD instantly. WHAT YOU GET • PD in millimeters, ready to enter at checkout. • Single (binocular) PD, the value most retailers request. • A clear, guided flow with on-screen tips for good lighting and head position. • Re-measure as many times as you like and average your results for confidence. WHO IT'S FOR Anyone buying prescription or blue-light glasses online, parents checking a child's fit, or anyone who simply wants their PD on hand without booking an appointment. A NOTE ON ACCURACY PD Meter provides an estimate based on your photo and the card scale. Results depend on lighting, camera angle and how precisely you place the markers. For high prescriptions or progressive lenses, confirm your PD with an optician. This app is not a medical device.
