If you're running a protocol, a good tracker handles the dosing math, reminders, and injection-site rotation so you don't have to. Here are the standouts we'd actually recommend, reviewed independently.
The most feature-complete tracker, with AI built in
Standout: AI woven into six points of the app that actually knows your stack, reconstitution math, and dose history
Currently the deepest peptide tracker on the market. Its AI isn't a generic chatbot — it works from your real protocol, dose log, and check-ins. Data stays on your device with no cloud requirement, and a Stealth Mode can disguise the app icon for privacy.
Visit Protocol →The most-reviewed dedicated tracker on the App Store
Standout: Fast protocol setup with smart reminders and exact syringe-unit math
Has the largest review count of any dedicated peptide tracker on the App Store. Schedules injections, sends discreet reminders, and calculates precise syringe units in one place. The free tier covers up to two protocols, with a paid upgrade for unlimited.
Visit PepTracker →Tracking plus genuine education
Standout: Visual body-map injection-site rotation
Pairs solid tracking tools with real educational content for people who take protocols seriously. The standout is a body-map feature that lets you mark injection sites on a diagram, making site rotation intuitive. Available natively on iOS and Android with web access too.
Visit PeptIQ →Free core features with a one-time premium
Standout: Stack Analyzer that scores your protocol across six dimensions
Its Stack Analyzer rates your stack on synergy, redundancy, side effects, practicality, goal alignment, and evidence quality, then plots it on a radar chart. Core features are free and premium is a single purchase — no recurring charges.
Visit Smart Peptide Tracker →Connects doses to your biometrics
Standout: Correlates protocols with HRV and sleep data
Goes beyond logging by tying your doses to your actual Heart Rate Variability and sleep architecture, so you can see how a protocol moves your physiological baseline over time. Best for data-driven users already wearing a sleep/HRV tracker.
Visit miora →Reconstitution + dosing math in one app
Standout: Solves dose, BAC water, reconstitution volume, and exact insulin-syringe units
A clean, fast calculator that handles the part people get wrong: how much bacteriostatic water to add, and how many syringe ticks a target dose works out to. Saves protocols for repeat use and supports multi-peptide blends. Frequently recommended in the community.
Visit PepCalc — Peptide Calculator →Free web reconstitution calculator
Standout: Instant, professional-grade reconstitution math with no signup
A no-friction browser tool for precise mixing and dosing — punch in vial amount, target dose, and water volume and it returns units immediately. Good when you just need the number without installing anything.
Visit PeptideCalc.io →Calculator with 30+ peptide presets
Standout: Presets for GLP-1s and complex blends like the Wolverine Stack and GLOW
A visual reconstitution calculator preloaded with presets for more than 30 peptides, including GLP-1s and multi-peptide blends, so you skip manual setup. Pairs the math with a clear visual guide.
Visit PeptideFox →GLP-1 dose plotter & half-life calculator
Standout: Plots dosing and half-life for retatrutide, tirzepatide, and semaglutide
Built specifically for GLP-1 users: it plots your dose schedule, estimates half-life and steady-state levels, and includes a BAC-water reconstitution calculator. Niche but excellent if you're running Reta, Tirz, or Sema.
Visit GLP3 Planner →Best for multi-compound stacks
Standout: Overlays lab biomarkers (testosterone, IGF-1, glucose) on your dose timeline
The strongest pick for people running multiple peptides at once. Beyond dose logging, it overlays lab panels onto the timeline so you can see how a stack tracks against your bloodwork over time.
