Baseline — Know What’s Actually Working Baseline is a personal research journal for people running peptide protocols. It is not a dose calculator, not a social network, and not a medical app. It is a simple tool for answering one question honestly: is this working for me? How it works 1. Write a hypothesis State what you think will change, in your own words. 2. Measure your baseline Log 3–10 days of daily check-ins before you start, using the measures that matter to you, such as pain, energy, sleep, mood, mobility, libido, mental clarity, or recovery. 3. Run the active phase Continue daily check-ins for 14–56 days. Log doses and note confounders like sleep, stress, and travel. 4. Read your trial report See a side-by-side comparison of your baseline and active averages for every measure, with trend lines and a plain-English summary you can screenshot and share. Why Baseline is different Calm and honest No hype, no claims. Baseline never tells you something is working. It helps you find out. Local-first and private Every check-in, dose, and photo stays on your device. No accounts. No cloud sync. No analytics on your health data. Built around the report Every screen in Baseline is designed to help you create one clear, trustworthy trial report at the end. Baseline Pro A single subscription unlocks the full research toolkit: Unlimited concurrent experiments CSV export of raw data Photo attachments for check-ins Up to 12 measures per experiment Custom measures beyond the built-in defaults Available monthly or yearly. Cancel anytime in your Apple ID subscription settings. Baseline does not diagnose, treat, or recommend. It is not a substitute for medical care. Consult a qualified healthcare professional before starting or changing any protocol. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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/

Verdict
The clearest difference is ratings volume: Peptide Tracker at 53 against Baseline's 1. On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Baseline sells 2 in-app purchases, starting at $4.99 per month and Peptide Tracker sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Baseline against 5.0 for Peptide Tracker. That said, the two scores are not equally well evidenced: Peptide Tracker has 53 ratings behind it against 1, so its average is the more settled of the two.
Baseline ships an update weekly, Peptide Tracker every 5 days. The most recent releases landed on October 10, 2026 and October 22, 2026 respectively.
