Lighter is a gentle intermittent fasting companion. Track your fasting
window, log the daily habits that support it, and see your progress over
time — without pressure or guilt.
TRACK YOUR FAST
• Start and stop your fasting window with one tap
• See at a glance whether you are fasting or in your eating window
• A live countdown on your home screen widget and in a notification —
check your remaining time without unlocking your phone
• Flexible plans, from a gentle 12:12 to longer windows
• Pause your plan any time you need a break
LOG THE DAILY BASICS
• Water intake
• Weight
• Calories
• Steps — read from Health Connect, or entered manually
• Build your own daily tasks and reorder them to fit your routine
SEE YOUR PROGRESS
• Fasting streak, total hours and longest fast
• Weight trend over time
• Daily and weekly summaries
LEARN AS YOU GO
A built-in library of short, plain-language articles: how to start safely,
why your first fast does not need to be long, what benefits research
actually points to, what body signals matter for women, and practical
answers like whether you can drink coffee or exercise while fasting.
REMINDERS THAT RESPECT YOU
Optional reminders for your fasting window, water and weight check-ins.
Turn any of them off individually — Lighter will not nag.
YOUR DATA STAYS YOURS
Your fasting sessions, weight, water and step data are stored on your
device. Sign-in is optional and only needed for a cloud account and
Lighter Plus. Step data read from Health Connect is displayed on-device
only — it is never uploaded, never shared, and never used for advertising.
You can export your data or delete your account and all associated data
at any time, from inside the app or from our website.
LIGHTER PLUS
Lighter is free to use. Lighter Plus unlocks the full experience and is
available as a monthly or annual subscription, or a one-time lifetime
purchase. A 72-hour full-access trial starts when you create an account.
Subscriptions renew automatically unless cancelled at least 24 hours
before the end of the current period. Manage or cancel any time in the
Play Store under Payments & subscriptions.
IMPORTANT
Lighter is not a medical device and does not provide medical diagnosis,
treatment or advice. Intermittent fasting is not suitable for everyone.
If you are pregnant or breastfeeding, under 18, have a history of eating
disorders, diabetes, or any medical condition, please consult a
healthcare professional before changing your eating pattern.
