OMAD tracker
Most fasting apps are built for 16:8 and treat OMAD as an afterthought. OutLast is built for the 23:1 protocol — it scores your daily compliance, tracks how your single meal makes you feel, and shows you whether your one-hour eating window is actually working.

The problem
16:8 fasting apps give you an 8-hour eating window and call it fasting — that's not even close to OMAD
Generic trackers count calories across multiple meals when your entire day is one plate of food
Timer apps start and stop a countdown but don't track how you feel, score your compliance, or measure your consistency
OutLast tracks your 23:1 protocol with daily scoring, eating window precision, energy tracking, and a streak counter built for one meal a day
How it works
Tap, describe what you ate, done. Steak and eggs. Salmon bowl. Chicken and rice. OutLast timestamps your meal and calculates your fasting window automatically — no timers to start or stop.
OutLast scores your OMAD compliance every day. Hit your 23:1 window, log your meal, and your score reflects it. Break the fast early or eat twice — your score tells the truth.
Log energy and mood with your single meal. Over weeks, you’ll discover which foods, meal times, and patterns give you peak performance on OMAD — and which ones leave you dragging.
What you get
OutLast natively understands the 23:1 fasting schedule. No need to manually configure windows or fight with apps designed for shorter fasts. OMAD is a first-class protocol, not a workaround.
Get a daily score based on how well you stuck to your one-meal window. Consistent 23:1 days score high. Slips and extra snacks bring it down. Simple, honest accountability.
Log how you feel after your single meal in one tap. See which foods and meal times give you sustained energy vs. the ones that spike and crash. Your data reveals the ideal OMAD plate.
Your eating window is just one hour. OutLast tracks it to the minute — when you started, when you finished, and whether you stayed inside your target. Precision matters when the margin is this tight.
The science
What people say
“Every fasting app I tried was built for 16:8. I had to hack settings to get a 23-hour fast and they still didn’t score it properly. OutLast just gets OMAD. Log the meal, see the score, keep the streak. That’s all I needed.”
“The energy tracking opened my eyes. I was eating pasta for my one meal and crashing every night. Switched to steak and vegetables after seeing the pattern in OutLast and my energy completely leveled out. Data doesn’t lie.”
“I’ve done OMAD for over a year but never tracked it consistently. OutLast made it effortless — one tap, done. My longest streak is 67 days and the daily score keeps me honest even on weekends.”
