## What is Fastify?

Fastify is the intermittent fasting tracker built for lasting weight loss. Pick a plan, tap start, and watch the weight come off the natural way.

Unlike apps that count calories, Fastify helps you lose weight by timing your meals — a simpler, more sustainable approach backed by decades of research.

WHY FASTIFY

Fastify combines everything you need for successful intermittent fasting in one clean app: a personalized plan built around your BMI, a simple timer, weight tracking, hydration support, and gentle reminders. No calorie counting. No complicated setup. Just a focused fasting companion designed around how you actually live.

PERSONALIZED FASTING PLANS

Start with the plan that fits your body and lifestyle:
- 16:8 — the most popular fasting window
- 18:6 — for faster results
- 20:4 — the Warrior Diet
- OMAD — one meal a day

- 5:2 — flexible weekly fasting
- Custom — build your own

Our fasting plan calculator creates a schedule tailored to you. No guesswork.
