DoneDose vs PepTracker: Peptide Tracker Comparison (2026)

PepTracker and DoneDose both serve people who inject medications, but they specialize in different aspects of the workflow. PepTracker is a peptide-specific tool focused on dose calculations, syringe volume math, and protocol scheduling. DoneDose is a broader injectable tracker with a visual body map for site rotation that works across all medication types. The overlap is smaller than you might expect.

Quick Verdict: Choose PepTracker if you run peptide protocols and need in-app syringe volume calculations, reconstitution math, and protocol-specific scheduling. Choose DoneDose if you want a visual body map for injection site rotation, need to track oral medications alongside injectables, or want on-device privacy for your medication data.

Side-by-Side Feature Comparison

Core Features

PepTracker exists because peptide protocols have a math problem that other injectable medications mostly don't. When you reconstitute a lyophilized peptide with bacteriostatic water, you need to calculate how many units or milliliters to draw in your syringe to get a specific microgram dose. That calculation depends on how much water you added, the total peptide content of the vial, and the syringe type you're using. Get it wrong, and you're underdosing or overdosing. PepTracker builds that calculation into the logging workflow — you enter your vial specs, and the app tells you how much to draw. For someone running multiple peptides, each reconstituted at different ratios, this eliminates a real source of daily friction and error.

PepTracker also handles protocol scheduling in a peptide-aware way. Peptide protocols often involve specific timing patterns — five days on, two days off; morning and evening dosing; cycling schedules that change week to week. The app understands these patterns rather than forcing you into a generic "every day at 9 AM" reminder model.

DoneDose's core is different. It doesn't help you calculate what to draw — it helps you track that you drew it, confirm where you injected, and build an adherence record over time. The one-tap logging flow is fast: notification, open app, confirm dose, select site on body map, done. The body metrics layer (weight, mood, appetite, energy) captures how you're responding to your protocol, which is useful context when evaluating whether a peptide is working.

These are complementary more than competitive. PepTracker answers "how much do I inject?" DoneDose answers "where did I inject and am I staying consistent?"

Injection Site Tracking

This is the clearest differentiator.

DoneDose's visual body map shows all available injection sites on an anatomical diagram. Each site is color-coded: ready-for-use sites are visually distinct from recently-used sites that need more recovery time. When you log a dose, selecting the injection site is integrated into the same flow — you're not navigating to a separate screen or logging it as an afterthought.

This matters more for peptides than many users realize. Peptide protocols often involve daily or twice-daily subcutaneous injections. At that frequency, you're using injection sites rapidly, and proper rotation becomes essential to prevent tissue irritation, bruising, and the formation of scar tissue that impairs absorption. The injection site rotation guide covers why rotation matters clinically; DoneDose enforces it practically.

PepTracker does not include a visual body map for site rotation. Its value proposition centers on the calculation and scheduling side of peptide management. If you're tracking sites with PepTracker, you'd need a supplementary system — a separate app, a notebook, or memory. For a once-weekly injection, memory might suffice. For twice-daily peptide injections across a multi-compound stack, memory fails fast.

If your main struggle is figuring out how much to draw, PepTracker solves that. If your main struggle is remembering where you injected yesterday morning, DoneDose solves that.

Medication Support

PepTracker is a peptide tracker. That's the scope, and within that scope it's focused and useful. If your entire injectable regimen is peptides — BPC-157, TB-500, CJC-1295, ipamorelin, or similar compounds — PepTracker covers the workflow. Understanding how long peptides last after reconstitution and how to store them properly are concerns PepTracker's user base cares about, and the app's design reflects that knowledge.

DoneDose supports any injectable medication — peptides, TRT, GLP-1 agonists, insulin, biologics — plus oral medications. If your regimen includes a peptide alongside TRT, or you're taking daily oral supplements with your injectable protocol, DoneDose handles everything in one place. There's no need to switch between apps or maintain parallel tracking systems. The guide on combining oral and injectable medication tracking explains why consolidation improves adherence.

The practical question: is your regimen all peptides, or is it peptides plus other things? If it's all peptides and you need dose calculations, PepTracker is more specialized for that job. If you're mixing medication types, DoneDose's breadth matters.

Privacy and Data

DoneDose stores all data on your device. No account creation, no cloud storage, no data transmission. Your peptide protocol, injection history, and body metrics exist only on your phone. Lose the phone, lose the data — but no one else ever has access to it.

PepTracker's data handling should be verified on the current App Store listing or the developer's privacy policy. Many health apps store data in the cloud for backup and sync capabilities.

People tracking peptide protocols often value privacy. The regulatory landscape around certain peptides is evolving, and many users prefer to keep their usage data entirely local. DoneDose's architecture guarantees that.

Price

DoneDose is free. Every feature is available to every user with no subscription, no premium tier, and no in-app purchases.

PepTracker's pricing should be checked on the current App Store listing, as it may vary or change over time.

User Experience

PepTracker's UX is built around the peptide-specific workflow: set up your compounds with vial information, let the app calculate your dose volumes, follow protocol-aware schedules. For someone managing three or four peptides with different reconstitution ratios and dosing schedules, this structured approach reduces cognitive load where it matters most — at the syringe.

DoneDose's UX is built around speed at the point of logging. The assumption is that you already know what you're injecting, and the app needs to get out of your way while capturing the data that matters: timestamp, dose confirmed, injection site recorded. The body map interaction is the distinctive piece — selecting a color-coded site on an anatomical diagram is faster and more informative than typing a site name into a text field or picking from a dropdown.

For the initial setup and calculation phase of a new peptide protocol, PepTracker's UX is more helpful. For the daily grind of logging doses and rotating sites over weeks and months, DoneDose's UX is leaner.

The body metrics in DoneDose — weight, mood, appetite, energy — add tracking dimensions that are relevant to peptide users. If you're running BPC-157 for recovery, logging daily energy and mood alongside your doses can reveal whether the protocol is having the effect you're looking for. That correlation doesn't require an analytics engine; it requires consistent data, which a fast logging flow encourages.

Who Should Choose PepTracker

PepTracker is the right choice if:

• Your regimen is exclusively peptides
• You need in-app syringe volume calculations for reconstituted peptides
• Protocol-specific scheduling (cycling, loading phases, split doses) is important
• You're new to peptide self-injection and need calculation guidance
• Dose accuracy is your primary concern — you want the app to help you get the math right

PepTracker's specialization is real and valuable. The syringe calculation feature alone justifies it for anyone who isn't confident in their reconstitution math. Getting your dose right is more important than tracking where you injected.

Who Should Choose DoneDose

DoneDose is the right choice if:

• Visual injection site rotation with a body map is a priority
• You inject frequently and need to rotate sites systematically
• Your regimen includes non-peptide injectables (TRT, GLP-1, insulin, biologics)
• You take oral medications and want everything tracked in one app
• You already know your doses and need a fast, reliable daily logger
• On-device privacy with no account or cloud storage matters to you
• You want a free app with no feature restrictions

DoneDose is the stronger tool for the daily logging and site rotation workflow. Once you've figured out your doses and your protocol is stable, the challenge shifts from "what do I inject" to "did I inject, and where" — and that's exactly the problem DoneDose was designed to solve.

Frequently Asked Questions

Does PepTracker have injection site rotation with a body map?

PepTracker focuses on peptide dose calculations and protocol scheduling rather than visual site rotation. DoneDose includes a visual body map with color-coded indicators showing which injection sites are ready and which need more rest time.

Does DoneDose calculate syringe volumes for peptides?

No. DoneDose does not include syringe volume calculations or reconstitution math. It focuses on logging doses, tracking injection sites, and monitoring adherence. If you need help converting reconstitution ratios to syringe volumes, PepTracker handles that in-app.

Can I track non-peptide medications in PepTracker?

PepTracker is designed specifically for peptide protocols. If you take other injectable medications (TRT, GLP-1, insulin) or oral medications, DoneDose supports all of those in a single app alongside any peptide tracking.

Which app is better if I'm new to peptides?

PepTracker's syringe volume calculations and protocol scheduling may be more helpful during the learning phase when you're figuring out how much to draw and when. DoneDose is stronger once you know your doses and need reliable daily logging with site rotation tracking.

Are these apps free?
