Peptide Tracker vs Stack

The dose calculators, 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, run the dose and vial-mix math, and never miss a shot. The AI coach, the one paid feature, reads your own labs, protocols, and injection history, and it's built to say "I don't know" instead of guessing. WHAT'S FREE (and stays free) • Dose, blend, and half-life calculators • 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, and weight sync from Apple Health or Health Connect • Reminders and notifications • Light and dark mode • JSON export, anytime No account. No analytics. No cloud. Your health data lives on your phone. I can't see it, sell it, or lose it. 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 is $9.99/mo or $59.99/yr: unlimited AI coach conversations with photo attachments, unlimited lab PDF parsing, and unlimited nutrition and supplement-label scans. 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/

Stack keeps the supplements you already take organized — build your stack, get one calm reminder per moment, and log everything in a single tap. BUILD YOUR STACK Add the supplements you take, with your own doses and your own times. Pick from a small library of common gym supplements or add anything custom. Every library entry is general information with a cited public source. ONE REMINDER PER MOMENT Items due at the same time arrive as one notification, not five. Quiet hours are respected, and one gentle re-prompt is the maximum — no nagging. LOG IN ONE TAP Mark a whole time slot taken with a single tap. Skipping is fine too — history stays neutral, with no streaks and no guilt. TIMING NOTES, NOT ALARMS When your own schedule puts two items together that are commonly taken apart, Stack shows a quiet, dismissible note. Information, never alerts. STACK PRO Free keeps full tracking for up to 5 items, with reminders. Pro unlocks unlimited items, multiple stacks (cut / bulk), training-day schedules, and history export. Stack is an organizer. It shows general information from cited public sources — it does not give medical advice, recommend supplements, or suggest doses. Talk to a healthcare professional about what's right for you.
