Tech Spark Smart Fitness Band | AI Recording & Fitness Tracking

Lightweight fitness band with heart rate and sleep tracking—all-day wear for the minimalist athlete. The Tech Spark Fitness Band is smaller and lighter than full smartwatches, so you truly forget you're wearing it. Real heart-rate monitoring, sleep tracking with REM/light/deep stages, step counting, calorie tracking, and silent vibration alarms work all day without sucking the battery.

Design & specs: OLED dot-matrix display (always-on or tap-to-wake), 1.2" screen, 5ATM waterproof, 14-day battery (no constant charging), Bluetooth 5.2. Magnetic USB charging. Works with Fitbit app and most iOS/Android fitness apps via API.

Fits the lifestyle of: Morning joggers and gym regulars who hate smartwatch bulk, people who lose or forget expensive watches, sleep anxious users, anyone who wants fitness data without the tech-fashion statement, and minimalists generally.
