Transform is a six-month body-transformation protocol for people who want progress they can measure, not guess at. Training, food, recovery and bloodwork on one instrument, with an AI coach that reads your actual numbers. Most apps count calories, or count reps. Transform connects them, then shows what changed. WHY IT WORKS • A weekly body scan that scores your physique and plots the trajectory • Macros that update the moment you log, not at the end of the day • A gym tracker that remembers every set and tells you what to beat • Bloodwork turned into a supplement plan you can act on • Answers built from your data, not from a generic article THE WEEKLY BODY SCAN One photo a week, scored on muscle, body fat, symmetry, posture and definition against a labelled scale. The photo stays in your private gallery and the trajectory charts across weeks. Change is slow and easy to miss in the mirror — this is the receipt. FOOD, LOGGED FOUR WAYS • Text — write "2 eggs and toast" and let AI do the maths • Photo — snap the plate, check items and macros before they land • Barcode — scan the packet • Quick add — your usual foods, ordered by how often you eat them Totals recalculate as you log, so the rings are right before you put the phone down. TRAINING THAT PROGRESSES • Set-by-set logging — weight x reps x RPE on one clean ledger • Browse by muscle and equipment — muscle map, form notes and a looping demo on every exercise • Rest timer between sets, plate meter for each load • Last session's numbers beside today's, so you know the target • PR history and volume by muscle group • Presets for PPL, Upper/Lower, Full Body and Bro splits, or build one BLOODWORK THAT CHANGES YOUR STACK Upload a panel as a PDF or photo. Transform reads the markers — testosterone, ferritin, A1C, lipids and more — flags anything outside the reference range, and suggests supplement changes you can apply in one tap. Text is extracted on your device and files are encrypted at rest. Transform does not diagnose or treat anything, and reminds you to take results to a clinician. A COACH THAT KNOWS YOUR WEEK Ask why the scale has stalled or to swap tonight's dinner, and the answer is built from your logs, targets and trend. Meal swaps apply straight to the day's plan. PROGRESS YOU CAN READ • One composite score, banded so the number means something • Weight chart with your goal line and moving average • A calendar heatmap of every day you showed up • Progress photos in a scrubbable timeline ALSO INSIDE • Supplement stack by time of day, with 7-day adherence • Apple Health, Whoop sync • Lock-screen and home-screen widgets • Full data export and account deletion in Settings THE 26-WEEK PROTOCOL Choose cut, bulk, recomp or maintain; Transform calibrates four phases around it: • Calibrate (wk 1-4) — bloodwork, baseline lifts, sleep audit • Compound (wk 5-14) — heaviest training block, macros locked • Refine (wk 15-22) — weight target hit, strength held • Lock (wk 23-26) — re-test, re-photograph, set the new baseline BUILT FOR FOCUS iPhone, iOS 18+. Dark by design. No streak parades, no motivational confetti — just the numbers, put where they are hard to ignore. TRANSFORM PRO — AN AUTO-RENEWING SUBSCRIPTION Transform runs on a Transform Pro subscription covering food logging and the food database, the AI coach, the weekly body scan, weekly reviews, bloodwork parsing and recommendations, and analytics.

Pepstack helps you take the right supplements at the right time, built around your real routine, not a generic label. HOW IT WORKS Tell Pepstack your goals, your diet, and anything that's bothered you before. It builds a personalized shortlist from a catalog of real, sourced products, every pick shows the reason it was chosen, whether that's your goal, your diet, or a reaction you flagged. YOUR SCHEDULE, NOT A GENERIC ONE Add anything to your daily schedule and Pepstack places it around your actual day, your meals, your sleep window, instead of just a flat list of times. Known timing conflicts (like zinc and iron needing space between them) are flagged before they become a problem. BUILT ON REAL RESEARCH Every product in the catalog links back to real, verifiable research citations, not marketing copy. Ask a question and get an answer sourced from that same catalog, with a way to report anything that looks wrong. A REFERENCE LIBRARY, NOT A DOSING TOOL Pepstack also includes a peptide reference library for research purposes: what each one is, its general category, and research trends. It does not provide doses, protocols, or injection guidance for peptides. TRACK WHAT YOU ACTUALLY TAKE Log what you've taken, see your streak, and export your own data whenever you want. Your account and everything in it can be deleted at any time, right from the app. Pepstack works offline for your day-to-day tracking and syncs when you're back online.
