Fasting works. Remembering when you started, when to stop, and whether you're on track? That's the hard part. Hold Fast makes it effortless. Whatever your reason for fasting, Hold Fast keeps up. Some people fast to manage their weight. Others do it for metabolic health, steady energy, sharper focus, longevity, spiritual practice, or simply the discipline of it. Hold Fast doesn't push one goal on you. It just tracks your fast, cleanly and reliably, so you can focus on why you started. Tap once to start your fast. Watch the timer count up on your Home Screen, Lock Screen, and Dynamic Island, without even opening the app. Hit your goal, log the win, and build a streak you can actually see. That's the whole idea: a fasting app that gets out of your way. No noise, no clutter, no ads. Just a clean timer and the data that keeps you consistent.
