How it works

A coaching rhythm,
not a data dump.

Most apps show you numbers. Megron tells you what they mean and what to do today.

Link Apple Health or Health Connect for activity, sleep, heart rate, HRV, cardio fitness, weight, and workouts. Your history powers the coaching from day one.

Get clear answers

Megron answers the questions that matter: are you in a deficit, why did weight change, should you push or deload, and is the plan working?

Adjust as your body adapts

Adaptive TDEE, deficit safety checks, and honest goal timelines keep the plan grounded in what's actually happening — not generic formulas.

What you get

Four engines,
working quietly in the background.

Each is useful on its own. Together they're a coach that understands your body.

AI Weekly Focus

A single coaching priority each week — what to prioritize, why it matters, and when to reassess.

Adaptive TDEE

Your calorie budget recalibrates to real-world results — not textbook formulas — so intake stays aligned with your body.

Deficit safety checks

We quietly flag when a deficit slips too aggressive and help you reset before effort turns into burnout.

Goal realism

Projects honest timelines from your observed rate of change — no fantasy deadlines, no generic formulas.

Trust

Built for coaching,
with privacy in view.

The app explains what data powers the experience and keeps privacy, sources, and support easy to find.

You control health data access

Megron only reads the Apple Health or Health Connect categories you authorize. You can change health permissions anytime in your device settings.

Clear AI disclosure

Selected app data may be sent to OpenAI for coaching narration, summaries, meal parsing, photo meal estimates, and plain-language explanations after in-app consent.

Sources are built in

Health, nutrition, calorie, and macro calculations link to in-app sources. Megron is for general fitness guidance, not medical advice.

Why Megron

Built by a couple who wanted
the app they couldn't find.

Megron = Megan + Ron. A husband-and-wife team of fitness enthusiasts — backed by 20+ years of software engineering experience and real-world training — who kept hitting the same wall with every tracker on the market: lots of data, no guidance.

We built Megron to be the coach we wanted: one that reads your real health signals, respects the science, and tells you the one thing worth focusing on this week — with the reasoning behind it.
