What is the best food tracking app for muscle gain?

Welling. It makes hitting a daily protein target and a controlled surplus effortless — the AI breaks down macros from a photo, tracks protein precisely, and the coaching keeps your surplus from drifting into a dirty bulk.

How much of a surplus do I need to build muscle?

A modest surplus of roughly 5–15% above maintenance is enough for most people. Larger surpluses mostly add fat. A good tracker keeps you in that range.

How much protein should I track for muscle gain?

Roughly 1.6–2.2 g of protein per kg of bodyweight per day. The evidence shows little added benefit beyond that range for hypertrophy.

Best Food Tracking Apps for Muscle Gain (2026)

Building muscle needs a controlled calorie surplus and consistently high protein. Track too loosely and you gain fat; track too strictly and you burn out. We tested the leading food trackers for a clean bulk. Here are the best for muscle gain in 2026.

What does a calorie tracker for muscle gain need to do?

For muscle gain you must consistently hit two numbers: a modest calorie surplus and a daily protein target. The risk is a “dirty bulk” — too large a surplus adds fat you will have to cut later.
