SteadFast is the fasting tracker for people who don't need hand-holding. No gamification. No social features. No recipe databases or meal planners. Just a clean, focused tool that helps you build the daily discipline of intermittent fasting—and track the results. BUILT FOR REAL PEOPLE WITH REAL GOALS Whether you're dealing with prediabetes, high blood pressure, weight that won't budge, or just want to reclaim control of your health—SteadFast gives you what you need and nothing you don't. This isn't a game. It's a practice. A daily commitment to mental toughness as much as metabolic health. WHAT YOU GET - Timer with four proven fasting protocols: 16:8, 18:6, 20:4, OMAD - Progress tracking: fasting history, completion stats, weekly summaries - Science library: understand the "why" behind fasting without the hype - BMI tracking: simple health metrics, no overcomplicated dashboards - Clean interface: dark background, gold accents, zero clutter WHAT YOU DON'T GET - No badges or streaks that guilt-trip you into opening the app - No community posts or social comparison features - No upsells disguised as "challenges" or "premium content" - No busy UI designed to keep you scrolling SteadFast is intentionally simple. Start your fast, finish your fast, track your progress. That's it. CHOOSE YOUR PROTOCOL 16:8 — The foundation. Fast for 16 hours, eat within an 8-hour window. Perfect for building consistency. 18:6 — Step it up. An extra 2 hours of fasted state for deeper metabolic benefits. 20:4 — Advanced discipline. A 4-hour eating window for experienced fasters. OMAD (One Meal A Day) — Maximum mental toughness. One meal, one sitting, complete focus. Switch between protocols as your body adapts. No judgment, no locked features—just flexibility to progress at your own pace. THE SCIENCE LIBRARY Clear explanations of autophagy, metabolic switching, insulin sensitivity, and fat adaptation—the mechanisms that make fasting work. No pseudoscience. No overblown claims. Just peer-reviewed research in plain language. FASTING IS MENTAL TRAINING Every time you push past the urge to eat when you're not actually hungry, you're building something bigger than willpower. You're proving you can commit to a decision and follow through. That discipline transfers. The focus you develop during a fast doesn't disappear when the timer ends. It shows up in your work, relationships, and ability to handle stress. SteadFast tracks the physical results—weight trends, fasting streaks, completion rates. But the real transformation happens in your head. WHO THIS IS FOR Adults who've tried everything. People dealing with health wake-up calls who need discipline, not distraction. Anyone tired of apps that treat fasting like a video game instead of a serious health practice. If you're looking for an app that cheers you on with cartoon characters and sends you 12 notifications a day—this isn't it. If you want a tool that respects your intelligence and your time—welcome. BUILT BY SOMEONE WHO GETS IT SteadFast was created by a veteran who understands that real discipline isn't flashy. It's showing up every day and doing the work, whether you feel like it or not. This app exists because the alternatives were exhausting—too many notifications, too much noise, too much trying to make you "engage" instead of just letting you fast. HOLD THE LINE Fasting isn't easy. Some days you'll want to quit. SteadFast doesn't pretend otherwise. It gives you the structure to stay consistent and the data to see what's working—because discipline compounds when you track it. SUBSCRIPTION OPTIONS - Monthly: $2.99 (cancel anytime) - Annual: $19.99 (cancel anytime) All subscriptions unlock full access to all protocols, progress tracking, and science content.
