Best body recomposition apps (2026), compared

The best body recomposition app is one that tracks the evidence a recomp actually produces: a rising strength trend, protein adherence, a flat-ish trend weight and changing measurements or photos. Arrow puts lifts, food and trend weight in one iPhone app. GainFrame is built around progress-photo body-composition estimates. MacroFactor is the established adaptive nutrition app, and Hevy is a popular free lifting log. Most people end up needing either one app that covers several of these jobs or a deliberate combination.

The hard part of a recomp is that your main progress signal, the scale, is the one that barely moves. If fat goes down and muscle goes up at the same time, bodyweight can sit still for months. So you need other signals, and you need them in a place where you'll actually look at them together.

Disclosure: we make Arrow. We've tried to be specific about where other apps are the better choice. Every competitor price and feature below was checked against the company's own site, help center or App Store listing on October 17, 2026. Sources are at the end.

01TL;DR

• Want lifts, food and trend weight in one app: Arrow. A full lifting log, Smart Scan food logging, adaptive calorie targets and a weekly recap that covers training and nutrition.
• Want photo-based body-fat and muscle estimates: GainFrame. Its analysis estimates body fat, FFMI and 12 muscle groups from progress photos.
• Want the most established nutrition algorithm: MacroFactor. $71.99/yr per app; its nutrition and workout apps don't adjust each other.
• Want a free lifting log: Hevy. Pair it with a food app and a tape measure.

02Who can realistically recomp?

Recomposition happens most readily in a few groups. Barakat and colleagues' 2020 review in the Strength and Conditioning Journal concluded that it's also possible in trained lifters, but usually slower.

• Beginners. New training is a strong stimulus, so muscle gain at maintenance or a small deficit is common.
• Returning lifters. Regaining lost muscle tends to be faster than building it the first time.
• People with higher body fat. More stored energy makes it easier to build muscle without a surplus.
• Trained, lean lifters. Possible, but slow. Many will make faster visible progress with dedicated cut and lean-bulk phases.

The common requirements across that research: progressive resistance training, high protein (the ISSN position stand puts active people at about 1.4–2.0 g/kg/day, and many recomp protocols aim near the top or a bit higher), and calories near maintenance or a small deficit. Longland et al. found lean mass gain and fat loss at the same time in a deficit when protein was high and training was hard.

03What to track on a recomp

Because the scale won't tell the story, use four signals:

1. Strength trend. Reps or load on your main lifts going up over weeks is the clearest sign you're building muscle.
2. Measurements and photos. Waist going down while arms, chest or thighs hold or grow. Same lighting, same time of day, every 2–4 weeks.
3. Trend weight. A smoothed line, not daily readings. Flat or slowly drifting is expected. A steady climb or drop tells you whether you've drifted into a bulk or a cut.
4. Protein adherence. How many days a week you hit your target. A recomp with low protein usually stalls.

A food-only app covers 3 and 4. A lifting log covers 1. A photo app covers 2. That's why app choice matters more for recomp than for almost any other goal.

04The apps for recomp, compared

Prices are US list prices on October 17, 2026, from each company's own site or help center. Where a fact couldn't be confirmed on an official page, the table says so.

How to read it: GainFrame is strongest on measuring the body. Arrow and MacroFactor are strongest on the inputs (food and training) and the weight trend. If photo body-comp estimates matter to you, GainFrame alongside a food-and-training app is a reasonable stack.

05A practical recomp setup

Calories. Start at estimated maintenance or 10–15% below if you have more fat to lose. Let an adaptive app correct the estimate after a couple of weeks of real data.

Protein. Aim for about 1.6–2.2 g/kg of bodyweight daily as a common starting range. Spread it across 3–5 meals.

Training. A structured program with progressive overload on compound lifts. If your top sets aren't creeping up over a month, something's off: sleep, protein or the program.

Weekly check (5 minutes):

• Trend weight flat, lifts up, waist down: textbook recomp. Keep going.
• Trend weight rising, waist rising: you're in a surplus. That's a lean bulk, not a recomp. Trim 100–200 kcal.
• Trend weight falling quickly, lifts dropping: you're cutting, and maybe too hard. Add calories back toward maintenance.
• Everything flat for 8+ weeks: consider whether a dedicated cut or lean bulk would move you faster.

In Arrow, the weight chart shows Scale Weight against Trend Weight with your estimated daily deficit or surplus, so you can see whether you're really near maintenance. The adaptive TDEE unlocks after about 7 complete logged days and 2 weigh-ins at least 7 days apart, and each weekly check-in moves calories by no more than 150 kcal. Your PRs and per-exercise history live in the same app, and Arrow Coach's weekly recap covers nutrition and training together. Take photos and tape measurements alongside it, or use a photo tool like GainFrame.

If you decide a phase is the better route, see what's the best app to track a cut and the best app for a lean bulk. For more on keeping lifts and food in one place, read Is there one app that tracks both workouts and macros?

06When another app is the better choice

• You want body-fat and muscle estimates from photos: GainFrame. Arrow doesn't analyze progress photos.
• You want the most established adaptive nutrition algorithm: MacroFactor.
• You want to pay $0 for lifting: Hevy's free tier. Smart Scan, Arrow Coach and other AI features need an Arrow Diamond subscription.
• You're on Android: Arrow is iPhone-first. Hevy, MacroFactor and MyFitnessPal are on Android.
• You track micronutrients closely: Cronometer (Gold $59.99/yr).

07FAQ

What's the best app for body recomposition tracking?

Pick one that tracks strength, protein and trend weight together, then add photos or measurements. Arrow covers lifts, food and trend weight in one app; GainFrame focuses on photo body-composition estimates; MacroFactor focuses on adaptive nutrition.

How do I track recomp progress if the scale doesn't move?

Watch your strength trend on main lifts, take waist and limb measurements and photos every 2–4 weeks, and check that you're hitting your protein target most days. A flat trend weight with rising lifts and a smaller waist is what recomp looks like.

Can you lose fat and build muscle at the same time?

Yes, especially for beginners, returning lifters and people with higher body fat. Trained, lean lifters can too, but it's usually slower.

How much protein do I need for a recomp?

A common starting range is 1.6–2.2 g per kg of bodyweight a day. Research on deficits with hard training supports aiming toward the higher end.

Should I eat at maintenance or a deficit for a recomp?

Maintenance or a small deficit (around 10–15%) is typical. If you have more fat to lose, a small deficit usually works well; if you're already lean, closer to maintenance.

Is GainFrame good for recomp?

It's built for the measurement side: it estimates body fat, FFMI and muscle groups from progress photos. Treat the numbers as estimates and pair them with your strength and nutrition data.
