The best body recomposition apps in 2026
When you recomp, the scale barely moves. These apps show what does, and which one tells you if it’s working.
Short answer
The best body recomposition app is ProgressLens: it compares your waist with your arms and shoulders over matched photos and tells you whether you’re losing fat, losing muscle or recomping, on iPhone and Android. Pair it with MacroFactor for calories or Hevy for strength. GainFrame and Recomp AI give photo or 3D estimates on iPhone.
Disclosure: we make ProgressLens. Details about other apps come from their own store listings and websites as of November 2026; prices and features change, so check the listing before you pay. We name each app’s weaknesses and our own.

FAQ
Frequently asked questions
What is the best body recomposition app?
ProgressLens, because it’s built to answer the recomp question directly: is the fat going down while muscle holds or grows? It reads matched photos plus waist, arm and shoulder measurements.
Is there a free body recomp app?
Free apps can log weight and photos (Hevy, a spreadsheet), but none tells you whether it’s fat or muscle that changed. Our free fat vs muscle calculator gives a one-off answer from two weigh-ins and body fat readings.
How do you track body recomposition?
Waist and arms weekly, matched photos every two weeks, and strength in the gym. Waist down plus arms holding means recomp. Read how to track body recomposition.
At what body fat should I recomp?
Recomp works best for beginners, people returning to training, and those at moderate body fat (about 15–25% for men, 25–35% for women). See what body fat to bulk, cut or recomp.
