Why I Created CoolFire Smart Hydration Coaster? Hi, I'm David - the creator of the CoolFire Smart Hydration Coaster. For years, I had a bad habit of drinking very little water. Eventually, I developed a kidney stone. One day, the tiny stone moved into my urinary tract, causing unbearable pain—doctors say it's one of the most painful experiences, comparable to childbirth. It wasn't considered an emergency, so I lay in the hospital bed for two hours waiting for a doctor. Fortunately, the stone passed into my bladder before treatment, and I was able to go home. But I'll never forget that pain. With a background in electronics and Bluetooth engineering, I created CoolFire to help myself—and others—stay hydrated and avoid similar health issues. It's more than a smart coaster. It's a wellness tool designed to build better habits and support your daily routine. Smart Hydration Reminder That Works with Any Drinkware CoolFire is a smart hydration reminder disguised as a sleek, voice-activated LED coaster. It works with any cup, mug, or bottle—no need for a bulky smart water bottle. Just place your drink on it, and CoolFire uses voice alerts, ambient light, and a customizable app to remind you to stay hydrated throughout the day. Customizable Wellness Assistant Track hydration in milliliters or oz and set personalized water intake goals based on gender, height, weight, and activity level. Customize ambient lighting and voice settings to match your routine. Create voice messages for daily tasks like “Take your pills,” “Walk the dog,” or “Water the plants.” Built-In Talking Clock and Time Management Tools Press the top button to hear the time, calendar, and hydration progress. Set alarms, nap timers, and hourly chimes via the app. Works offline once programmed - settings are saved directly on the Smart Coaster. Stylish Design with Swappable Covers Includes themed, non-slip silicone covers (floral or bird motifs) that absorb condensation and stay put—no sliding around like other coasters. Compact and elegant, CoolFire fits perfectly on desks, bedside tables, or kitchen counters. Perfect Self-Care Gift CoolFire is ideal for students, seniors, remote workers, caregivers, and wellness enthusiasts. Whether you're gifting a health-conscious friend or upgrading your own setup, CoolFire is a stylish, smart-tech solution that inspires better habits—one sip at a time.
