Glucose flat all day and the 14-hour window held. Tonight's weigh-in lands after a salty dinner, so expect noise and trust the trend.

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, right where 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 make this 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 is 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 works on your phone with no setup and is wired into your actual day: your logs, your diary, your trend lines. If you want deeper replies, you can optionally connect your own AI from Claude or ChatGPT.

  • On-device keto coach, ready with no setup
  • 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
  • Optionally connect your own AI key from Claude or ChatGPT for deeper replies
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.

Thirty minutes checking and rechecking a grocery list, twice a week, is a common keto-beginner time sink.

Googling whether something is keto often takes longer than actually cooking it.

Questions

Fair questions, straight answers.

Can I actually download it right now?
Yes. Keto28 v1.21.2 is live for Android and you can download it from this page today. It is the full app, not a preview. An iPhone version and a Google Play listing are planned, so today the Android download is a direct install.
What exactly is the Keto Coach?
A coach engine that runs on your phone with no setup and is 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. If you want deeper replies, you can optionally connect your own AI by plugging in your own Claude or ChatGPT 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.
What does founding pricing actually lock in?
Founding members pay $59.99 a year for Coach and keep that price for as long as the subscription stays active. After the Founding 200 are claimed the price moves up the ladder shown above. The 3 day trial comes first, and if you cancel before it ends you are not charged.
