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/

Track your prescribed TRT for free — doses, reminders, injection sites and lab results. No account. Your health records stay on your device. Testosterone first, plus the other medications in your prescription, such as hCG. Up to 3 active protocols are free. FLEXIBLE SCHEDULES Injections, gels, creams, patches, oral, nasal, buccal or pellets, as a named product or a custom one. Several times a day, chosen weekdays, exact intervals such as 84 hours, or long intervals with loading doses. Enter the syringe units your prescriber or pharmacist gave you; they show on your doses and reminders. Your injection-site history makes rotation easy. REMINDERS THAT KEEP GOING Dose reminders run as long as your protocol does. A missed dose gets a nudge, and the daily check-in reminder stays quiet on days you've logged. LABS AND A VISIT BRIEF Unlimited lab results with units, lab reference ranges, draw timing and comparability notes. An illustrative testosterone level estimate based on population data, for supported products. A clinician visit brief as a PDF. CARE RECORDS Appointments, prescriptions and refills, travel preparation, weekly check-ins and supply tracking. BACKUP AND CSV Back up and restore with Files or iCloud Drive. CSV export, and CSV import of past doses and labs. Optional, read-only Apple Health import. WIDGETS, LIVE ACTIVITY AND SIRI Your next dose on the Home Screen and Lock Screen. Ask Siri when it's due, or log it by voice.
