Okno: Intermittent Fasting

Okno is a calm, honest intermittent fasting tracker. No "lose 10 kg in a month", no ads after every tap and no 20-question survey before you can start.

A TIMER THAT DOESN'T DRIFT
We store the moment you started, not a ticking counter. Time stays right after a restart, a time zone change, a flat battery or battery saver. Forgot to tap Start? Set when you stopped eating — even last night. Start, end and goal of any fast can be edited.

YOUR DAY ON A DIAL
The home screen is a window onto the sky of the current hour with a 24-hour dial: see when you fast, when your eating window opens and how long until your goal.

PROTOCOLS FROM 12:12 TO OMAD
12:12, 13:11, 14:10, 16:8 and 18:6 are free. 20:4 and OMAD come with Awaytix Pass. A timer of any length is always free: just change the goal.

A SCHEDULE FOR YOUR LIFE
Softer weekends? Shift work like 2-on-2-off or 24 hours on, 3 off? Okno sets the protocol and window time for each weekday or shift cycle.

PROGRAMS
"Gentle start" — four weeks from 12:12 to 16:8, free. With Pass: 16:8 to 18:6, 5:2 for a month, towards one meal a day.

WHAT GETS IN YOUR WAY
Mark why you ended early: hunger, eating with others, stress, tiredness, a workout. Okno shows which weekdays and hours are hardest, how hunger changes by fasting hour, and gives a specific tip. Share a 30-day report with your doctor.

WATER, WEIGHT, WELLBEING
One-tap water, weight with a weekly average (no panic over water swings), hunger and wellbeing on a 1–5 scale and symptoms. Dizzy or weak? The app suggests ending the fast.

SCIENCE WITHOUT MYTHS
Eleven short articles with links to research (NEJM, JAMA, Nature Reviews, EFSA): what works and what doesn't, what probably happens hour by hour, riding out hunger, what you can drink, who shouldn't fast. No "autophagy at hour 16".

SAFETY FIRST
A screening at the start: pregnancy, breastfeeding, diabetes on insulin or sulfonylureas, eating disorders, under 18, underweight. Based on your answers Okno limits fast length or offers a gentle mode. Answers stay on your phone.

WIDGET AND NOTIFICATIONS — FREE
A home screen widget, a timer in the notification shade with a progress bar, "time to start" and "goal reached" right on time, even at night. Start a fast straight from a notification or the widget.

FREE FOREVER
Timer of any length, back-dating, 5 protocols, Gentle start, widget and notifications, water, weight, wellbeing, journal, weekly summary, all articles, 10 languages. No ads on the timer, plan or journal.

Weekday and shift schedules, 20:4, OMAD and 5:2, all programs, the full "what gets in the way" breakdown, a report for your doctor, cloud backup and transfer, no ads. No trials and no silent charges. One Pass unlocks all Awaytix apps.

IMPORTANT
Okno is not a medical device and does not diagnose, treat, cure or prevent any medical condition. We do not promise any particular weight loss. Talk to a healthcare professional before fasting, especially if you have a chronic condition or diabetes, are pregnant or breastfeeding, or have a history of eating disorders.
