Gut health tracker
Most gut health apps make you log stool charts and FODMAP scores. You don’t need that. OutLast is the gut health tracker that connects what you eat to how you actually feel — so you can spot the foods that fuel you and ditch the ones that don’t.

The problem
Some meals leave you energized and sharp. Others leave you bloated, foggy, or crashing — but you can't pinpoint which ones
You suspect a food sensitivity but don't have the data to prove it — so you keep eating the same things and wondering why you feel off
Gut health apps like mySymptoms and Cara Care want you to log bowel movements and rate stool consistency — that's not what you signed up for
OutLast keeps it simple: log meals + how they made you feel. Track probiotics and supplements. Spot the patterns. Eat what actually works for your body
How it works
After each meal, log what you ate and tag how you felt — energized, bloated, foggy, great. It takes 5 seconds and builds a powerful dataset over time.
Log probiotics, fermented foods, bone broth, and anything else supporting your gut. See your consistency streak grow as you build the habit.
After a few weeks, your data tells the story. See which meals correlate with high energy and which ones consistently leave you feeling off. No guesswork — just patterns.
What you get
Tag each meal with your post-meal feeling — energized, bloated, foggy, or great. Over time, you'll see exactly which foods your body loves and which it doesn't.
No elimination diet needed upfront. Just log consistently and let the data reveal which foods correlate with bloating, low energy, or brain fog.
Log probiotics, kombucha, kimchi, yogurt, and other gut-supporting foods. Build a streak and see how consistency with gut health habits affects how you feel.
OutLast tracks your energy alongside your meals. Compare what you ate on your best days vs. your worst — and start eating for how you want to feel.
The science
What people say
“I finally figured out that dairy was causing my afternoon brain fog. I’d suspected it for years but never had the data. Two weeks of tracking with OutLast made it obvious.”
“I love that OutLast doesn’t make me rate my bowel movements. I just log what I eat and how I feel. Simple. After a month I could clearly see which foods were dragging me down.”
“Started tracking my probiotic and bone broth routine alongside meals. The difference on days I’m consistent vs. days I skip is wild. Now I have the data to prove it.”
Questions
Your gut is trying to tell you something. Log what you eat, track how you feel, and let the data reveal which foods fuel you — and which ones are holding you back.
