The system

Most keto apps count carbs. This one carries you through the month.

Almost everyone who quits keto quits in the first three weeks — at the exact cliffs Keto28 is engineered around. Every day has a lesson, a mission, and a reason.

The 28-day program

Day 1 purges the kitchen. Day 4 teaches you to surf a craving. Day 15 warns you about the week-3 wall before you hit it. Daily missions, XP, streaks, and milestone science — a program with a syllabus, not a feed.

Numbers that explain themselves

Carbs, glucose with a live A1c estimate, ketones in real units (blood, breath, or strips), weight trend, fasting windows, water and electrolytes. Every target shown with YOUR math — and a doctor-ready PDF when you want one.

Safety-first science

A plain-English keto classroom with mastery quizzes, a symptom triage that separates "annoying but normal" from "call your doctor today," and medication-aware warnings built in from day one. No bro-science.

The marquee

A coach that read your chart before it answers.

Generic chatbots give generic advice. The Keto28 Coach is wired into your actual day — your logs, your diary, your trend lines — and coaches like it has skin in the game.

  • Reads today's macros, fasting window, sleep, and diary before every reply
  • Adapts tomorrow's mission when your week goes sideways
  • Safety rails: real symptoms route to the medical triage, never to pep talk
  • Bring your own model — run it with your own LLM key, or ours
KETO28 COACH
I caved. Pizza at the office thing. Whole day's ruined anyway, right?
One meal can't undo eleven logged days — but the story you're telling yourself can. Log the pizza exactly as it happened. Your next meal is keto. Not Monday — the next one.
fine. logged it
Good. Expect a pound or two of water on the scale; it's gone in days. Your 14-hour fast still fits tonight if dinner ends by 8 — want me to move tomorrow's mission to account for the carb refeed?
Hardware-grade tracking

Your body, on instruments.

Live vitals over Bluetooth

Pair blood-ketone meters and heart-rate straps for live readings instead of manual entry. Watch ketosis arrive in real units — not vibes.

COACH BETA

Proof, kept private

Photo-proof missions and progress photos live in a private vault inside the app — never your gallery, never a cloud. Day 1 vs day 28 is a comparison you own.

EVERY TIER
Your year, returned

The time keto usually takes from you, itemized.

Keto28 is built around the small decisions beginners repeat until they burn out. The app does the recurring work so the month feels planned, not improvised.

Questions

Fair questions, straight answers.

When does the beta launch?
The app is real and running on devices today — we're hardening it for public beta. Waitlist members get invites first, in signup order, on iOS and Android.
What exactly is the AI Coach?
A coach engine wired into your actual data. Before it answers, it reads today's macros, your fasting window, sleep, and diary — then coaches with context. It adapts your plan, calls out patterns, and routes emergencies or anything medical to the built-in safety triage instead of guessing. Power users can plug in their own LLM API key.
Where does my health data live?
On your phone. Tracking, photos, and diary entries are stored on-device by default — progress photos go to a private in-app vault, not your gallery or a cloud. You choose what leaves, like a PDF report you export for your doctor.
Is this medical advice?
No. Keto28 is a tracking and education tool with unusually serious safety rails — an 18+ gate, medication-aware warnings, and triage that tells you when to call a professional. Talk to your doctor before changing your diet, especially on medication.
Why join the waitlist instead of waiting for launch?
Three reasons: you get the beta first, you get founding pricing we will never offer publicly, and your answer to "why do you want this" genuinely steers what we build next.
