GainLens

See your progress. Not just feel it.

Available on Android & iOS

GainLens uses AI to analyse your weekly physique photos and give
you what the mirror can't - an objective score, body fat estimate,
muscle breakdown across 15 groups, and a personalised coaching
message every single check-in.

WEEKLY CHECK-INS THAT ACTUALLY TELL YOU SOMETHING
Take a front, back, or side photo. GainLens analyses it in seconds
and returns an overall physique score, symmetry rating, conditioning
score, and estimated body fat range. No guessing. No bias. Just data.

YOUR AI COACH IN YOUR POCKET
After every check-in, your AI coach tells you exactly what's working,
what's holding you back, and what to prioritise in the next four weeks.
Specific, actionable, and based on what it can actually see.

TRACK EVERY MUSCLE GROUP
See scores for all 15 muscle groups - chest, lats, delts, arms,
quads, hamstrings, glutes, calves and more. Know which muscles are
lagging before they become a problem.

PROGRESS CHARTS THAT MOTIVATE
Watch your overall score climb and your body fat trend downward over
weeks and months. A timeline of every check-in with photos, scores,
and coaching messages - your transformation, documented.

CREATE SHAREABLE CONTENT
Generate before-and-after cards in one tap. Post your transformation
to Instagram, TikTok, or anywhere else. The progress is yours - show it.

STAY CONSISTENT WITH STREAKS
Weekly check-in reminders, streak tracking, and accountability keep
you coming back. Consistency is the only variable that matters.

PRIVATE BY DEFAULT
Your photos never leave your device. Analysis is done securely and
your photos are stored locally - not on our servers.
