Fast & Circadian Bio-Instrumentation

Eat'Less

A simple meal and fasting timer for iPhone.

"Food is not just sustenance, it's a way of life."

One of the quotes inside the app

Eat'Less is a simple, beautiful timer for the time between your meals.

Tap + MEAL when you eat, and Eat'Less shows how long it has been, which metabolic phase you are likely in, and how close you are to your fasting goal.

Bio-timeline stages

The Eat'Less Physiological Continuum

Default goal: 16 hCustomizable
0h – 3h

Anabolic Phase

Rest & digest. Your body is absorbing the last meal.

3h – 6h

Post-Absorptive

Blood sugar settles and glycogen stays stable.

6h – 12h

Catabolic Phase

Glycogen stores are being burned for energy.

12h – 18h

Metabolic Switch

Glycogen runs low and fat burning takes over.

18h – 24h

Ketosis

Ketone levels rise as fat becomes the main fuel.

24h+

Autophagy

Deep fast, associated with cellular cleanup.

Precision toolkit

Crafted for Quiet Daily Mastery

Every feature is designed to be experienced in seconds, leaving your attention on your life.

Live Timer Since Last Meal

A to-the-second timer showing exactly how long it has been since you last ate.

Estimated Metabolic Phases

Your likely physiological state, moving smoothly from Rest & Digest to Fat Burning, Ketosis and Autophagy.

Satiety Ring Draining

A ring that drains as fullness fades, so you can see where you are without reading a number.

Multi-Day Circular Dial

Switch the dial between your last 24 h, 48 h, 5 days or 7 days, with every meal plotted around it.

Fasting Goals: 12 to 24 Hours

Pick a 12, 14, 16, 18, 20 or 24-hour goal and watch your progress toward it.

Undo Last Meal with One Tap

Tapped + MEAL by accident? Remove it in one tap and your timer picks up where it was.

Uncompromising architecture

Private by design: no account, no ads, no tracking. Everything stays on your iPhone.

Eat'Less contains no analytics, no ad networks and no servers that receive your data. Your meal times are saved only on your device, and deleting the app erases them.
