Mero VS MacroFactor

Mero's answer

Most macro apps give you one daily target and leave you to work out the food. Mero starts from your training week.

• Plans around your training. Mark each day as hard, easy or rest. Protein stays steady, carbs go up on hard days and down on rest days, and every portion is sized to that day's calories and macros.
• Ends in one grocery list. The week comes with a single shopping list and a batch prep plan, so you know what to buy, what to cook and what to eat.
• No logging. Check meals off if you want. Mero uses those check-offs and your weight trend to shape next week's plan.

Mero's answer

Choose Mero if you already know your macros but keep falling apart on execution: what to buy, what to cook, and what to eat when Tuesday runs late.

• Trackers like MyFitnessPal and Cronometer log what you already ate. Mero plans the week before it starts, so there's nothing to look up or log.
• Most meal planners work to one flat daily target. Mero plans each day for its training load, with more carbs on hard days and fewer on rest days.
• Recipe apps give you meals but not the week around them. Mero ends in one grocery list and a batch prep plan.

Mero's answer

Mero is built for serious recreational athletes and busy professionals who train with intent: people with a structured training week whose food isn't structured yet.

They usually:

• Know their numbers already, or want them set for them, and need help turning macros into actual meals.
• Train on a schedule with hard, easy and rest days, and want their food to follow it.
• Prefer planning and batch prep to logging every meal after the fact.

Mero's answer

I was the heavy kid at 220 lbs at 14 years old. For about ten years after that, I tried everything. Endless cardio, crash diets, random rules. I'd lose the weight, put it back on, and do it again.

In 2022 I looked back and couldn't find any progress. I wasn't stronger, faster or better at anything. The effort was never the problem. The system was.

That year I learned to count macros. I studied industrial engineering, so I treated my week like a process: count, adjust, and work out what a week has to look like for results to last. It worked. I got down to 150 pounds, kept it off, and still cooked food I wanted to eat.

The catch was doing it all by hand. Every week I turned a changing training week into meals, one grocery trip, a prep session and a decision about what to eat today. Knowing my numbers was easy. Living them week to week wore me out.

So I built Mero to do everything I used to do myself. It sets the targets, plans every meal, sizes the portions, writes one grocery list and plans the prep. Hard days get more fuel, and rest days get less. It runs on rules, not generative AI, so the same inputs give the same plan every time.

Today I train for ultramarathons. I finished my first 50K in 2026, and my next race is a 100k in April. No two days in my week need the same food. That's the week Mero was built for.

Mero is a native-feeling iPhone app backed by a small, rules-based planning engine.

• iOS app: React Native with Expo, written in TypeScript
• Backend API: Laravel (PHP), with Sanctum for authentication
• Subscriptions: RevenueCat on top of Apple's App Store billing
• Website and free planner: Cloudflare
• Email: Resend

How the plans are built. Mero runs on rules, not generative AI, so the same inputs always give the same plan. Calorie targets start from the Mifflin-St Jeor equation and shift with your hard, easy and rest days. Food macros come from USDA FoodData Central or the product's own label.

Mero's answer

• Recreational athletes training for a goal
• People who lift and run in the same week (hybrid athletes)
• Busy professionals who train on a fixed schedule
• People who already track macros and want the week planned for them
• People who have tried all the tricks and never see results
