Read full description

The blood-level charts, reminders, and full protocol tracking are free. No trial, no paywall, no catch. Most peptide and TRT apps charge for exactly this. I don't. Frontload is built for people running serious peptide and TRT/HRT protocols. Track every injection, watch your blood levels rise and fall between doses, keep every vial and dose organized, and never miss a shot. The AI coach reads your own labs, protocols, and injection history, and it's built to say "I don't know" instead of guessing. The coach and Cloud Backup are the paid part. WHAT'S FREE (and stays free) • Progress photos with a voice guide that lines up every shot the same way, then compare any two side by side. Your photos stay on your phone. • Blood-level PK chart: peak, trough, and steady-state, per compound • Injection logging with site rotation • Full inventory: every peptide, HRT compound, GLP-1 (semaglutide, tirzepatide), supplement, and med • Phased protocols with automatic on/off scheduling • Titration schedules: gradual dose adjustments over weeks, auto-stepping • Lab result tracking and trend charts • Macro logging • Sleep, fitness, weight, and food sync from Apple Health • Reminders and notifications • Light and dark mode • JSON export, anytime No account needed. Your health data lives on your phone unless you turn on Cloud Backup, and I never sell it. The app sends a few basic signals, like which version you're on and whether it was opened today, so I can find and fix bugs. Never what you log, and never what you ask the coach. THE AI COACH (Pro) Not a chatbot. Not a correlation engine. An actual coach with direct access to your full health context (labs, protocols, peptide stack, GLP-1 doses, nutrition, sleep, fitness, side effects), plus a curated knowledge base of peptide and HRT references. It reads a lab PDF, scans a supplement label, analyzes a side-effect cluster, and explains it in plain language. Grounded in your own data, not the internet's. Pro adds unlimited AI coach conversations with photo attachments, unlimited lab PDF parsing, unlimited nutrition and supplement-label scans, Cloud Backup, and Frontload on your computer at app.frontloadapp.com. Cloud Backup and the web app are for paid plans, not the free trial. The price for your region shows in the app before you subscribe. WHO BUILT THIS Frontload is a one-person project. I'm in the HRT and peptide community myself, and I wanted a tracker that didn't feel cold and clinical, so I built the one I wanted, with every feature I needed. I had my wife test it the whole way through, so it isn't built only for the guys. She told me what women actually need in a tool like this: cycle-aware tracking, the right hormone panels, and a tracker that doesn't assume everyone's a man on TRT. It's all in here. I gave it to one friend, hoping to help him. He gave it to another. That's how Frontload has gotten everywhere it's gotten so far. No ads. No growth team. The mission isn't to get rich. It's to cover the cost of running the app and build something genuinely useful to people on their HRT and peptide journeys. The AI Coach engages with compounds, doses, and protocols directly, but it's not a doctor. Always discuss any protocol change with your prescribing physician. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Serious tracking for peptides, GLP-1, TRT and HRT, with the bloodwork to see what actually changed. A precision instrument for people who run their own peptide, GLP-1, HRT and TRT protocols. Record an injection, a pill or a spray in a few taps, or let scheduled protocols run on auto-pilot. Log your workouts, water, meals and periods in the same place. Local-first and private. No efficacy claims, no gamification, no guilt. TRACK PROTOCOLS • The largest compound library in any tracker: peptides, GLP-1s, hormones and supplements • Record what you take in seconds, with titration schedules and cycle calendars • Injection-site rotation on a body map, with recently used sites marked before you pick one • Modeled Exposure: an estimate of what's on board now and where each blood draw fell on the curve • Adherence history and a verdict when a cycle ends TRACK YOUR PERIOD • Log periods, symptoms and waking temperature, with a calendar and a dial that shows where you are in your cycle • Perimenopause and menopause read from your own logs, including a hot flash count • Birth control reminders. Fertile days and ovulation are shown as estimates only, never as birth control • Your cycle data is never used for analytics LOG YOUR WORKOUTS • A library of 250+ exercises, each with a short demonstration of how it's done • Last time's numbers beside every set, a rest timer, and personal records marked as you hit them • Starter templates, a workout calendar, and progress charts for every exercise FOOD AND WATER • AI food log: type or photograph a meal, review the estimate, correct it, approve. Nothing logs without your review. • One-tap repeat meals, recipes, serving sizes, and targets you set yourself • Log water in a tap from the app, a widget or Siri, with reminders through the day KEEP INVENTORY • Vault: fridge, freezer and shelf zones, cap colors, and supply runway tied to your protocols • Photograph a kit's packing list to add vials in bulk UNDERSTAND YOUR BLOODWORK • Import lab PDFs or photos and confirm every value before it counts • Trends across every report and every lab, with printed originals always preserved • Ranges shown are the ones printed on YOUR report. Optional Pro overlay: literature ranges, cited on screen, labeled educational • Doctor-Ready PDF: protocols, adherence, history and labs in one document CONNECT YOUR BODY • Apple Health, Oura, WHOOP and Withings: sleep, HRV, resting heart rate and weight against your cycles • CGM glucose: time in range, and your glucose curve against your injections • A health score and biological age computed from your own labs TRACK YOUR HOUSEHOLD • Add a partner with their own protocols, logs, bloodwork and insights, kept separate, under one membership • One tap switches between people, a distinct color shows whose data you're viewing, and one shared Vault links vials to either person PRIVATE BY DESIGN • Local-first: your data lives on your device, with optional encrypted cloud backup you control • No ads, no data sales, no social feed WHAT PEPTIDELAB IS NOT PeptideLab is a personal record-keeping and education tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. It never recommends, suggests, or changes a compound, an amount, a schedule, or a protocol. Every protocol in the app is one you enter yourself. Always consult a licensed clinician before you start, change, or stop any protocol or supplement. PeptideLab Pro (subscription) unlocks unlimited protocols, Modeled Exposure, the Lab Assistant, bloodwork trends and the Doctor-Ready PDF, Apple Health, Oura, WHOOP and Withings, CGM glucose reports, health score and DEXA body composition, household profiles, Food Log photos, protocol reports, and full history beyond 30 days. Core tracking and CSV export are free, forever. Privacy Policy: https://peptidelabapp.com/privacy Terms of Use (EULA): https://peptidelabapp.com/terms
