GainFrame: Gym Progress Photos
AI Body Fat Tracker & Scan
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Meet Coach — AI that reads your real check-ins and explains every score, body-fat shift, and trend. Now with a cleaner Day view to ask "why?" the moment you see a number.
The only progress photo app with AI body analysis AND an AI coach that explains it. Take a photo, get instant body fat estimates, physique scores, and muscle-group breakdowns -- then chat with Coach about what changed and why.
WHAT MAKES GAINFRAME DIFFERENT
Most apps just store your photos. GainFrame actually analyzes them — and now talks to you about them. Our AI examines each check-in to estimate body fat, score your physique, and identify which muscle groups are developing. Then Coach — a private AI chat grounded in your real numbers — answers your questions about it all.

more I’ve been using this fitness app for a little while now, and I genuinely love how simple and motivating it is. Instead of focusing only on numbers like weight or calories, it lets you track your progress through photos. It’s been such a game changer for me.As a mom, my body has gone through a lot of changes, and it can be hard to see progress day to day. This app helps me actually see the small changes over time, which is incredibly encouraging during this stage of my life. Some days the scale doesn’t move, but the visual progress reminds me that my efforts are still paying off.I also appreciate how easy it is to use. It doesn’t feel overwhelming or time-consuming, which is important when you’re juggling a busy schedule with kids. It’s become a really positive, low-pressure way for me to stay consistent and feel good about taking care of myself.Overall, I’d definitely recommend it to anyone, especially moms or anyone in a season of life where traditional fitness tracking feels discouraging. It’s a refreshing and motivating approach to progress.

This app is really helpful for keeping track of my fitness progress over time. The layout is clean and easy to use, and I like how simple it is to upload and compare photos. It makes it easier to stay motivated because you can actually see the changes instead of just guessing. The features feel useful without being complicated, and everything runs smoothly. Definitely a solid app if you’re serious about improving and staying consistent.
Developer Response Thanks for much for the kind words, we are very happy you are enjoying the app

As someone relatively new to the fitness game, a big thing I wished I could justify was dropping $ to get DEXA scans for an accurate body fat % reading. But GainFrame helps to bridge that gap, as much as any photo-based application can. I’ve had bf% estimated via body clips, and GainFrame has yielded very similar numbers to those, so I truly feel like it’s accurate enough for most people.And from a purely app perspective, GainFrame is super clean and intuitive to use, with a ton of features. Super happy to see this on the market!

I came across this app and honestly wasn’t sure how much it could really tell me just from progress photos. After trying it I was pretty impressed. It actually gives useful insights about body fat, muscle groups, and overall progress in a way that’s easy to understand. Setup was quick and the reports are interesting to look through if your tracking your physique over time

Meet Coach — your private AI chat coach.
Coach explains your physique data, grounded in your real numbers. Ask
why your body fat moved this week, what a muscle score of 78 actually
means, or compare any two check-ins side by side.
• Pick a coaching style: Supportive, Data Nerd, or Direct
• Coach remembers context across conversations — no need to re-explain
your goals every time
• Tap Coach from any check-in to start a chat anchored to that day's
numbers
• Photo Comparison mode: pick two check-ins, let Coach analyze the deltas
Day view, redesigned:
• Coach now lives inline at the bottom of your score card — ask "why?"
the moment you see a number, no scrolling required
• Trajectory and Next Milestone merge into one TREND card so where
you've been and where you're going read as one story
• Precision Body Fat moves out of its own card and into the score card
itself — small PRECISION badge + 4-dot confidence meter beside your
BF number; tap the dots to see what your accuracy level means
Also new in 2.0:
• Score-forward monthly Pro reports replace the old summary view
• Progress Pulse pulls in multi-signal evidence from your trends and
surfaces it on day cards
• Hevy integration: connect your workout app so Coach and Insights see
your training context
• Precision Body Fat is now a single-tap fix path instead of a dead-end
alert
• Paywall preview sheets let you see Deep Dive and muscle scoring
before you upgrade

paging
• Cleaner trajectory narration that always matches your live data

• Faster launch: the Dashboard now appears noticeably quicker after you open the app.
• Smoother photo library: thumbnails are cached as you scroll, so revisiting cells you've already seen is instant.
• Day view polish: fixed a brief flash when photos first load and a horizontal-scroll glitch on multi-photo days.
• Deep Dive Compare: the bottom-of-page scroll bounce is gone.
• Plus a number of smaller fixes across navigation, layout, and image loading.
