Instant Pulse measures your heart rate in just 8 seconds using the built-in wide-angle camera of your iPhone or iPad — no extra equipment needed. Simply place your finger calmly over the camera, stay still, and the app will measure your heart rate and save the result automatically. If you are using an iPad without a camera flash, take your measurements in a well-lit environment, such as under direct sunlight or near a light source. FEATURES • Measure your heart rate in just 8 seconds using only your finger and the camera. • Apple Watch app with watch complications to see your latest reading at a glance. • Reads and writes your heart rate data to Apple Health, including background sync. • View your latest heart rate reading from Apple Health directly on your Watch complication or Home and Lock Screen Widgets — without opening the app. • Schedule daily reminders to measure your pulse regularly. • Home Screen and Lock Screen Widgets. DISCLAIMER Instant Pulse measures your heart rate accurately but is not a certified medical device and should not be used for medical diagnosis or treatment. Normal resting heart rate for adults ranges from 60 to 100 beats per minute. Consult your doctor if your resting heart rate is consistently above 100 beats per minute (tachycardia), or if you are not a trained athlete and your resting heart rate is consistently below 60 beats per minute (bradycardia) — especially if accompanied by symptoms such as fainting, dizziness, or shortness of breath.

About

dissolve

dissolve is a sleep induction tool built around one idea: the hypnagogic state. hypnagogia is the threshold between waking and sleep - where thoughts loosen, imagery drifts in, and the mind begins to let go. most sleep apps try to distract you into unconsciousness. dissolve tries to take you there directly. the session lasts five minutes. for the first two, you watch a field of slow, shifting light. the shapes breathe. the colors drift. your eyes grow heavy doing what they were going to do anyway. when prompted, you put the phone down. for the remaining three minutes, audio continues - gently distorting, slowing, dissolving - designed to follow you into the hypnagogic and go quiet once you're under. that's it. no library of sounds to curate. no guided meditation to half-listen to. no badge for your seventh night in a row. just a five-minute path to the edge of sleep. begin only when you're ready to sleep. the decision is part of the process.
