FastNow is a lifestyle and tracking tool, not medical advice. Consult your doctor before starting any fasting or calorie restriction program.
The base app is free and fully functional from start to finish. Sponsorship adds a few advanced extras, but the core app is complete without it.
Set your eating window, start the timer, and let the app track your consistency over time.
Track long fasting periods with phase progression, clear milestones, and a structured end plan.
Log your weight daily and watch the trend — not individual readings — to understand real progress.
Track daily steps, estimate your calorie burn, and build the habit that keeps your deficit sustainable.
Log meals once, reuse them daily, and keep your calorie intake tied to your target in one place.
Track protein and carbohydrate intake together with a simple daily view that keeps both targets in check.
See your trend, adherence, phase progression, and time remaining — all in one view.
Set your eating window, start the timer, and let the app track your consistency over time.
The intermittent fasting tracker supports any eating window — 16:8, 18:6, 20:4, or a custom schedule you define. A visual timer shows your current phase so you always know where you stand. Set your preferred window once and the app tracks whether you hit it each day, building habit consistency without decision fatigue.
Track long fasting periods with phase progression, clear milestones, and a structured end plan.
The extended fasting tracker is built for deliberate, longer fasting sessions — from 24 hours up to 60 hours or more. Visual phase progression shows you exactly where you are in the fast. Pre-planning the end and recovery prevents the rebound behavior that usually follows unstructured long fasts.
Log your weight daily and watch the trend — not individual readings — to understand real progress.
Daily weight logging gives you data. The trend line gives you signal. FastNow's weight tracker shows both so you can separate real fat loss from the natural day-to-day fluctuations caused by water, sodium, digestion, and sleep. React to the trend, not to single numbers.
Track daily steps, estimate your calorie burn, and build the habit that keeps your deficit sustainable.
Walking is the most underrated fat loss tool available. It increases your daily energy burn without the recovery cost of intense exercise, which means you can do it every day for months. The walking tracker keeps your daily movement measurable and consistent — the two things that actually determine long-term results.
Log meals once, reuse them daily, and keep your calorie intake tied to your target in one place.
Read the nutrition label, enter the food once, and reuse it every day after that. The calorie tracker keeps your intake measurable, your habits repeatable, and your daily totals visible without separating food logging from calorie control. Awareness is the whole point — it's what turns vague intentions into a working deficit.
Track protein and carbohydrate intake together with a simple daily view that keeps both targets in check.
Keeping protein high and carbohydrates controlled is one of the most effective combinations for fat loss and muscle retention. The macro tracker gives you one screen to see both targets so you can build meals that support satiety, body composition, and a sustainable calorie deficit — without tracking becoming its own full-time job.
See your trend, adherence, phase progression, and time remaining — all in one view.
The progress dashboard turns a vague goal into a structured time frame. Set a challenge between 30 and 180 days, define your goal weight, and the app calculates your daily calorie and burn targets around that window. Everything you need to stay on track — and nothing you don't.
The base app is free and fully functional for the full journey. Sponsorship adds a few advanced features, but they are not core to the app.
