About this app

FastNow helps you lose weight by building everything around the one thing that actually works: a calorie deficit. Food, walking, and fasting are tools that serve the deficit. The app keeps it at the center and gives you 90 days of structure to follow.

Here is how it works.

YOUR OWN DEFICIT, TRACKED SIMPLY
You set your daily target and log what you eat. No meal plans, no macros, no recipes, no food rules handed to you. The app keeps the running total, so you always know where the day stands.

WALKING AS YOUR MAIN MOVEMENT
No gym required. A daily walk widens the deficit, and you can repeat it at any weight. Log your walks and watch them add up.

FASTING WHEN YOU WANT A RESET
A longer fast is one tool you can use, nothing more. Run a water fast to kickstart the deficit or to reset after a heavy stretch. Skip it if it is not for you. The weight loss does not depend on it.

A 90-DAY CHALLENGE WITH A FINISH LINE
Open-ended "lifestyle change" is hard to stick to, because nothing ever has to happen. FastNow gives you 90 days, a starting weight, and a target, then tracks your progress the whole way. A clear start and a clear end beat willpower.

WHAT YOU GET, FREE
- Calorie and food logging with your own targets
- A daily walking log
- A fasting timer for resets
- The full 90-day challenge with progress tracking

OPTIONAL, FOR SPONSORS
Want to speak your meals instead of typing them? AI voice food logging is there for people who choose to support the project. The core app stays free to use.

FastNow was built by people who lost the weight and wanted a tool that matched how they did it. Set your target. Start your 90 days. Track your way down.
