A small act of thoughtfulness before your phone goes dark. "The Last 5%" is a communication support tool that automatically sends your location and a message to someone you care about — right before your iPhone battery dies. [Perfect for situations like these] ・Coming home from work or a night out: Automatically lets someone know "I'm on my way home" or "My battery's about to die, so I'll be out of reach" — before it's too late. ・Your child's phone: When your kid's phone is about to die after school or hanging out with friends, their last-known location is quietly sent to you before the connection is lost. ・Meeting up with friends: If your battery might not make it to the meetup, share your current location in advance for a smoother rendezvous. [Key Features] ・Detects low battery (5% or below) and automatically sends a message. ・Includes a map link with your current location so the recipient knows exactly where you are. [Simple to Set Up] This app works in tandem with iOS Shortcuts. Just follow the in-app guide to set up your own personal communication protocol — no tech skills required. ※ This app is a supplemental tool that leverages iOS system features. It may not function in all network conditions, so please use it as one of your everyday communication options rather than as a primary lifeline.
