PepTrac was built by peptide users who were tired of stitching together spreadsheets, calculators, and reminder apps that weren't designed for real peptide workflows. No ads. No vendor emails. No paywalls before you can even explore. Just a tool that works the way you actually track.

— Key Features —

• Dashboard View — See today’s shots, your progress, and what’s next at a glance. Quickly spot what’s due, what’s been completed, and what needs attention — without digging through menus.

• Quick Shot Logging — One-swipe completion with optional notes, site tracking, and flexible timestamps.

• Protocol Builder — Build flexible schedules for multi-peptide routines, including phased changes over time. Adjust timing or dosage anytime.

• Configurable Reminders — Get notified when your next shot is due, and set up personalized reminders tailored to your own schedule and preferences.

• Estimated Peptide Level Tracking — Define your personal target range and see where your levels stand, how long you'll remain within range, and when they may start to drop. Get alerted when you're approaching your low end — and when you've crossed it.

• Preparations + Pen Support — Create custom vial, blend, and pen preparations that instantly convert your chosen dose into units or mL. Mix a new vial mid-protocol with a different concentration? Enter the change and PepTrac automatically recalculates your future shots.

• Built-In Calculators — Reconstitution, custom concentration, blends, titration, and intranasal prep — all in one place.

• Daily Logs — Configure the metrics you want to track and add your own. Log how you're feeling and what's changing, so you have the data you need to measure results, side effects, and progress over time.

• Analytics — Graph your logged metrics alongside your protocol to spot what's working and what isn't.

• Injection Site Tracking — Automatic rotation with clear guidance on which areas to use next.

• Widgets — See today's shots and schedule status right from your Home Screen.

• Privacy First — No accounts. No sign-ups. Your data stays on your device.

— Who PepTrac Is For —

• Users running multi-peptide or phased protocols with changing timing and dosage.

• Anyone on GLP-1s, incretins, or longer half-life peptides who wants to stay within a consistent target range.

• Users tired of spreadsheets for reconstitution math and dose conversions.

• Anyone tracking symptoms or outcomes who wants logs connected to protocol timing.

• Busy users who want clear daily guidance without managing the details manually.

— Why We Built PepTrac —

We tried the other apps and kept running into the same problems — features that didn't work as described, workflows that weren't built for real-world use, and paywalls or account sign-ups before we could even try them.

What we really wanted was a way to connect our results to our protocols. It's easy to spend time and money experimenting without ever knowing what's actually helping. PepTrac was built so you can log what matters, tie those changes to protocol timing, and learn from your own data — instead of relying on opinions or trends.

We couldn't find an app that handled all of this, so we built it ourselves. Whatever you're working toward, we hope PepTrac helps you stay consistent and learn what works for you.
