Best nutrition apps for MMA fighters (2026)

We make Siloh. Here's how we judged:

1. Fits a fight camp. Does the app handle training that changes day to day, from technique work to hard sparring?
2. Meals, not just numbers. Does it tell you what to eat, or only count what you ate?
3. Weight management. Does it adjust targets as your weight moves, and does it handle a weigh-in date?
4. Free tier and price. What you get for nothing and what the paid tier costs.
5. Honest fit. Who each app is genuinely better for, including when that isn't us.

Comparison table

1. Siloh

Best for: fighters who want the training program and the food that fuels it in one plan.

Siloh is a nutrition and training app that plans your meals and your workouts as one system, so training days and rest days eat differently. Siloh Pro writes AI workout programs for MMA and combat sports (as well as lifting, running and hybrid), matched to your goal, experience and equipment, then plans your meals around that program.

• Pros: The meal plan follows your training, so a double-session day and a rest day don't eat the same. The plan adapts after a skipped session, and the AI coach answers questions about what to eat or how to train. Restaurant recommendations that fit your plan help on travel and fight weeks. Syncs with Apple Health and Whoop. The free app covers logging, recipes and grocery lists.
• Cons: Siloh has no weight cut tools and doesn't plan to a weigh-in date, so it's for fueling camp, not for making weight. The planning features need Pro. iPhone only for now, with Android coming soon. It's a newer app (launched July 30, 2026), so it has less track record than the others here.
• Price: Free. Siloh Pro has a 7-day free trial, then $19.99 a month or $149.99 a year.

2. RP Diet Coach

Best for: fighters who want each meal timed around their sessions.

RP Diet Coach, from RP Strength, asks when you work out and builds your day around it. Its documentation says a post-workout meal is scheduled right after your workout ends, and no meal is scheduled closer than 30 minutes before one starts. RP says the diet takes into account your training schedule and training intensity.

• Pros: Meal timing around training is built in, which suits two-a-day camp schedules. You choose your meals and foods, and the app tells you how much and when to eat. Weekly reviews adjust your calories and macros based on progress.
• Cons: It doesn't write training programs, so you need a coach or another app for that. Its documentation doesn't say macros change between training and rest days by default, though you can set targets manually for any day. No weight cut features.
• Price: Free to download with a subscription. The App Store lists monthly plans at $14.99 and $19.99 and yearly plans at $99.99 and $149.99, plus sale and referral pricing. RP offers a 30-day money-back guarantee.

3. CutCoach

Best for: wrestlers, MMA fighters and boxers whose main goal is hitting a weigh-in.

CutCoach is the one app on this list built specifically for combat sports weight cuts. Its App Store listing describes personalized plans based on your body, goals and competition date, with nutrition and hydration strategies, full meal plans, and tracking for weight, water and macros.

• Pros: Plans toward a specific competition date, which none of the general nutrition apps do. Includes full meal plans and water tracking.
• Cons: It's built around the cut, not the whole camp, and it doesn't write training. All features need a subscription. The listing markets cutting up to 10% of body weight; large rapid cuts carry real health risks, and the app itself says it doesn't give medical advice. Read our fight camp nutrition guide before you plan a cut, and involve a qualified professional.
• Price: App Store options range from $6.99 a week and $12.99 a month to yearly plans from $19.99 to $49.99, and $59.99 for lifetime access.

4. MacroFactor

Best for: fighters who want their targets to adjust as they diet down through a long camp.

• Pros: Estimates your energy expenditure from logged intake and weight trend, then makes dynamic weekly adjustments. Adjustments are adherence-neutral, so they're based on what you actually ate. You can set different macros for different days, so a hard sparring day can carry more carbs. A separate MacroFactor Workouts app covers lifting.
• Cons: No free version, and the company says there never will be. It counts food rather than planning meals. Training-day targets are something you set yourself, not tied to a schedule. No desktop version yet.
• Price: $11.99 a month, $47.99 every six months or $71.99 a year, with a 7-day free trial.

5. Cronometer

Best for: fighters on a budget who want accurate data, including micronutrients.

• Pros: The free Basic plan includes a barcode scanner and tracks up to 84 nutrients. Gold adds the Macro Scheduler, which sets different macro targets for different days of the week, which works if your camp follows a fixed weekly schedule. Available on iPhone, Android and the web.
• Cons: It's a tracker, not a meal planner. The Macro Scheduler works by day of the week, so it won't follow a schedule that changes. Gold is required for the scheduler.
• Price: Free. Gold is $10.99 a month or $59.99 a year.

6. Carbon

Best for: fighters who want weekly macro coaching and a lower yearly price than most coaching apps.

Carbon Diet Coach, co-founded by Layne Norton, sets macro targets for weight loss, gain, maintenance or reverse dieting, then adjusts them at weekly check-ins based on your results.

• Pros: Weekly check-ins with adjustable check-in days. Every plan includes all features. Food tracker with custom foods and recipes. iPhone and Android.
• Cons: It doesn't plan meals or training, and its site doesn't mention training-day targets or anything specific to combat sports. No free tier.
• Price: $11.99 a month, $59.99 for six months or $99.99 a year.

How to choose

If you want one app to write your MMA training and plan the food around it, use Siloh Pro. If a coach already handles your training and you want meals timed around sessions, RP Diet Coach fits best. If you need a structured plan to a weigh-in, CutCoach is the only specialist here, but keep the cut small and supervised. For tracking only, MacroFactor is the best adaptive option, Cronometer is the best free one, and Carbon is a solid middle ground. Whatever you use, the fight camp basics stay the same: steady protein, enough carbohydrate for hard sessions and slow weight loss. Our fight camp nutrition guide covers the targets.
