Ghost Fast

Fast Like a Phantom.

The only fasting tracker that doesn't know your name. No accounts. No tracking. Just you and your goals.

THE APP

Simple. Private. Powerful.

Ghost Fast timer screen

One-Tap Fasting

Start and stop your fast with a single tap. No setup, no friction.

Phase Tracking

See your body's metabolic state in real-time as you progress through fasting phases.

Your History, Your Device

Streaks, stats, and trends — all stored locally and encrypted on your device.

GHOST PROTOCOL

Your Data. Your Device. Your Rules.

Local-Only Storage

Your fasting data never leaves your device. No servers, no cloud sync, no data harvesting. Everything is encrypted using iOS Keychain.

Zero Identity

No email, no passwords, no "Sign in with Google." You open the app and start fasting. We don't know who you are — and we like it that way.

Encrypted Export

You own your data. Export your complete fasting history anytime and back it up to your personal cloud. We never see it.

OUR STORY

Why We Built This

We were tired of fasting apps that wanted our email before we could skip breakfast. Every timer came with an account wall, a subscription upsell, and analytics dashboards tracking our every tap.

We just wanted to time a fast. No profile. No social features. No weekly report emails. So we built the app we wanted to use — one that respects that your health data is nobody's business but yours.

“Ghost Fast exists because your health data shouldn't be someone else's business model.”

GHOST GUARD

Built-In Safety, Not Just Features

Ghost Fast is designed with restraint as a feature. We believe a fasting app has a responsibility to protect its users — not just help them fast longer.

  • 16-hour fasting cap for users with certain health conditions
  • Safe Start screening before your first fast
  • BMI-aware restrictions to prevent misuse
  • Streak detection that encourages rest days
  • Medical disclaimer and healthcare provider guidance

SAFE START SCREENING

Are you pregnant or nursing?
Do you have diabetes or blood sugar issues?
Do you have a history of disordered eating?
Are you under 18 years of age?

Answering “yes” to any question activates a 16-hour safety cap and additional guidance. Your answers stay on your device.
