TRT Log
Read full descriptionHide full description
A testosterone tracker for your whole TRT protocol: log every injection, see an estimated level curve between doses, and keep your labs in your own units, private on your iPhone. NEW IN 1.1: home and lock screen widgets, lab report scanning, and weight and blood pressure in your daily check-in. TRT Log is a record-keeping app for testosterone therapy, and for anything you inject alongside it, such as HCG. Log a dose in seconds, rotate sites properly, watch your bloodwork trend, and walk into an appointment with a summary instead of a notes app. TRACK A WHOLE STACK - Run several protocols at once, each with its own schedule and reminder - Daily, every other day, twice weekly, specific weekdays, every X days, or on/off cycles - Smart site rotation suggests the spot you have rested longest, and alternates sides - One reminder per dose: log it or snooze it right from the notification - No marketing, no streaks, no re-engagement pings BUILT-IN CALCULATORS, FREE - Reconstitution: enter vial amount, bacteriostatic water and your dose, get the exact syringe units โ and the nearest readable mark, so you know what you are really drawing - Free testosterone from total T, SHBG and albumin, using the Vermeulen equation BLOODWORK THAT MAKES SENSE - 25 markers including Total T, Free T, Estradiol, SHBG, Hematocrit, PSA, lipids, thyroid and IGF-1 - Switch between ng/dL and nmol/L, pg/mL and pmol/L โ enter results exactly as your lab reported them - Every draw is tagged trough, peak or mid-cycle from your own dose history, because a number means something different at each SEE WHAT HAPPENS BETWEEN DOSES An estimated level curve, modelled from published half-lives and scaled to your own lab results. Shown as a percentage of your protocol's steady state, never as a clinical figure โ because only a blood test shows your actual level. VIALS AND SUPPLIES Remaining amount, low-stock warnings, discard dates after reconstitution, and cost per dose. DOCTOR-READY PDF One tap to a summary of your protocols, laboratory results, administration history and check-ins. PRIVATE BY DESIGN Your doses, labs and notes stay on your device. No account, no cloud, no ads, no tracking. TRT LOG PRO Free forever: unlimited dose logging, reminders, site rotation, the estimated level curve for your protocol, both calculators, one protocol and five lab values. Pro unlocks unlimited protocols, unlimited labs with charts and unit switching, the level curve fitted to your own lab results, vial inventory, Apple Health, the PDF report and encrypted backup.

Instructor JP Pro
Read full descriptionHide full description
Instructor JP Pro is the culmination of over 20 years of careful hand-made work and experience from a professional trainer certified by the NSCA, with Harvard coursework in nutrition and computer science. Built on 3 pillars: - Exercise - Nutrition - Metabolism Unique identity: - No AI. This application does not generate content with artificial intelligence. - Made by the professional himself. Not built by a company or team of developers. - Privacy first. No real names, emails or phone numbers are required. Start from day one. No excuses Workout and diet programs come for free with the app. These are general hand-made professional programs by Instructor JP, covering 6 weight ranges, different training levels with exercise equipment or just your bodyweight. You can also record your heart rate with a Bluetooth-compatible device. Workout Builder This software allows you to create professional-grade workout programs tailored to the user, based on their specific training level, equipment, goals and limitations. Analyze your diet More than 7,000 foods from the United States Department of Agriculture database are available through the app. Discover exercises 500+ exercises, 150+ multi-angle slow-motion instructional videos. Each exercise has been cataloged to quantify its affinity for fat loss, muscle gain, specific training levels and much more. Science-based exercise and food substitutions The system analyzes 62 biomechanical data points per exercise to provide you with logical and safe exercise alternatives. If you don't have a specific food, the system searches the full database to find the closest food at a macronutrient and caloric level. Simplified complexity The goal is to open the app and immediately know what to do. The biomechanics, nutrition and algorithms work behind the scenes. Everything is shown through anatomical images, charts and videos. Metabolic Protocol - A function that is earned, not bought A bigger challenge. Not every day we expend the same amount of energy; therefore, not every day we require the same amount and type of food. The metabolic protocol is a unique system of real-time nutritional adjustment built by Instructor JP. It has been tested over 6 years with incredible success on many subjects; it is still in the testing phase but is available here already. It contains proprietary formulas and procedures that adjust the quantity and distribution of carbohydrates, fats, proteins and calories. Each heart rate recording recalculates the diet and provides the user with the required dietary adjustment via a simple protein shake. The metabolic protocol is an optional function. It's blocked by design until the user records their first 30 continuous days of diet and heart rate. Where was AI used? From day one I (Josรฉ Pablo Camacho Alvarado - Instructor JP) decided to personally write the code for the backend, databases, biomechanics, nutrition and algorithms. All of it is built from more than 20 years of experience and 15 years of manually compiled information which I finally translated into SQL and Python. For this mobile app, I made a different decision. My background is in Python, not mobile development, so I used Claude to write the app's code under my direction because, without it, the result would have been far less polished and would have taken an unreasonable amount of time. Claude built the interface. All the data, images, videos, algorithms, workouts and diets behind it are completely AI-free and come directly from my own hand-made work and effort. From JP Every day I use these systems with my clients and myself. This is the work of my life written in software, and it has taken thousands of days and nights. My goal with this app and its systems goes far beyond selling my expertise. It is really to help all the people who are willing to help themselves by providing the tools they need.
