Body Scan (new) Two photos, front and side, and Trayner measures you: neck, chest, waist, hips, arms, thighs and calves, plus shoulder width and limb lengths. A guided setup walks you through lighting, clothing and posing, and voice guidance talks you into position so you can stand across the room. Results show as honest ranges, with a body-fat estimate from the published Navy method, a skeletal-muscle estimate, waist-to-hip and waist-to-height ratios against WHO and NICE guidelines, and a posture read-out. Explore your figure in a 360° view, compare scans taken under matching conditions, and calibrate against your own InBody or FitQuest readings. Form Check Ask Trayner about any rep. Tap a cue on your form report to open a coaching chat seeded with your own results, and pin a fix straight into your plan. A new movement-profile radar shows where each lift is strong or weak across five dimensions. Share a form report, or the raw clip, from the report screen. Fasting A new fasting tracker in the Food tab: pick a protocol, start and stop with one tap, and get a reminder when your window opens or closes. Home cards show where you are in the fast. Also in this release • Sources & Methodology: every health figure in the app now links to the research behind it. • More reliable video and photo uploads on slower connections. • Fixes for translations, Android layout on gesture-navigation phones, and several crashes reported through TestFlight.

Updated from SDK 54 to SDK 57

Say hello to a faster, cleaner way to get around Trayner: • New quick-action button — tap + to start a workout, log food, snap a meal, weigh in, ask Trayner and more, all from one place. Press and hold to rearrange it or add your own favourite shortcuts. • Redesigned navigation bar — a lighter, frosted-glass tab bar with a smooth new highlight as you move between tabs. • Smoother transitions throughout the app when switching sections. And more to explore this update: • Exercise demos now move — looping video clips play across your workout, routines and the exercise library (and pause when off-screen to save battery). • Refreshed Strength & Form cards on Home — your rank crest and form level now sit in one cleaner card, with each medal coloured to its level. • Record a form check from anywhere — tap Record a check, then pick a muscle and exercise or just search for a lift, and the camera locks straight to it. • A clearer workout recap — the Muscle Split now highlights the exact muscles you trained on a full-body map, in each muscle's colour. • Daily recovery at a glance — each day on the Home calendar strip now shows a ring for that day's recovery score. • Apple Watch setup made easy — if your watch is detected but not connected, Home shows a quick "Set Up" card that walks you through it. Swipe it away once you're done. • Plenty of polish and reliability fixes — including tidier coach replies and small design touches — for a smoother, more responsive experience. Thanks for training with Trayner

The exercise experience just got a major upgrade: • Redesigned exercise details — new About, History, Progress, PRs, Strength and Form tabs put everything about a lift one tap away. • Full-screen exercise player — tap any demo to zoom in, slow it down, pause, and share, with a quick link to YouTube tutorials. • Personal Records, reimagined — see your Estimated 1RM, Max Weight, Max Reps and volume records in a cleaner, clearer layout. • Smarter search & filters — a faster search bar and a single visual filter to browse by equipment or body part. • Browse the full exercise library right from the Workout tab. • Bigger, clearer muscle diagrams across the Strength, Form and exercise screens. • Apple Watch workouts now notify you the moment they're logged. • Plus lots of polish and reliability fixes for a smoother, faster app. Thanks for training with Trayner — keep the feedback coming!

We've added a "Sources & Methodology" screen (Profile → About → Sources & Methodology, also linked directly from every health, nutrition, and recovery screen and the AI coach) citing the specific formulas and public health guidelines behind our calculations and recommendations — USDA Dietary Guidelines for Americans 2020–2025, Mifflin–St Jeor, the ISSN protein position stand, WHO, the Compendium of Physical Activities, and peer-reviewed research. Each source is a tappable link to a publicly accessible page (no login or paywall). The AI coach now also attributes its recommendations to their sources. I have also attached a pdf of screenshots of the above implementation.
