Know how your phone is doing — without picking it up. WristBuddy lives on your Apple Watch and shows what your iPhone is doing right now: battery, charging, Wi-Fi and cellular, motion, silent mode, Focus, lock state, air pressure, and thermal state — all glanceable from your wrist. SOUND FAMILIAR? • Phone charging in another room? Glance at your wrist and unplug it when it's ready. • About to walk into a meeting? Know it's really on silent without pulling it out under the table. • Charging it inside a bag, or tethering a hotspot? Keep an eye on its temperature and catch it running hot. • Left your phone away on purpose? Stay aware of anything urgent without breaking the moment.
