DoneDose vs Regimen: Injectable Tracker Comparison (2026)

Regimen and DoneDose are both built for people who inject medications, but they emphasize different parts of the injectable workflow. Regimen leans into dose calculations, peptide reconstitution, and progress correlation. DoneDose focuses on injection site rotation with a visual body map and simple, private dose logging. Both are legitimate tools — the right one depends on which part of your routine needs the most help.

Quick Verdict: Choose Regimen if you need a built-in dose calculator, peptide reconstitution features, or progress correlation that ties your metrics to specific protocols. Choose DoneDose if injection site rotation is your priority, you want a visual body map with color-coded site status, or you need to track oral medications alongside injectables with on-device privacy.

Side-by-Side Feature Comparison

Core Features

Regimen positions itself as an intelligent tracker for peptide, TRT, and GLP-1 protocols. Its standout capability is the built-in dose calculator — you input your vial concentration and desired dose, and the app tells you how much to draw. For peptides that require reconstitution with bacteriostatic water, this calculation step is where many people make errors, and having it built into the tracking app eliminates the need for separate calculators or math on napkins. The app's smart reminders are protocol-aware, meaning they understand the cadence of your specific regimen rather than just repeating a static schedule.

DoneDose's core is dose logging and site rotation. You add a medication, set its schedule, and the app reminds you when it's time. Logging is one tap. For injectables, you select your injection site on the body map as part of the logging flow. The app doesn't calculate your dose — it assumes you know what you're injecting and focuses on recording that you did it, where you did it, and tracking your adherence over time. The body metrics layer (weight, mood, appetite, energy) captures context that helps you and your provider assess how the protocol is working.

The philosophical difference: Regimen helps you figure out what to inject and correlate outcomes. DoneDose helps you track that you injected, where you injected, and how you're feeling. Both are valid needs, and for some users, both apps might make sense at different phases — Regimen during protocol setup and dose planning, DoneDose for day-to-day logging and site management.

Injection Site Tracking

DoneDose's visual body map is its defining feature. When you log an injectable dose, the app presents an anatomical body map where you tap the site you used. Each site is color-coded: sites that have recovered and are ready for use look different from sites that were recently used and should rest. Over time, the map builds a comprehensive rotation history.

This matters clinically. Repeated injections in the same site cause lipohypertrophy — hardened tissue that impairs absorption and can alter how your medication works. For peptide stacks where you might inject two or three different compounds daily, systematic rotation becomes critical. The injection site rotation guide covers the clinical reasoning; DoneDose enforces the practice.

Regimen's focus on site tracking is lighter. The app's strengths lie in dose calculation and progress tracking rather than in visual rotation management. If you're on a single weekly TRT injection, this may not matter much — you have a week between injections and can rotate mentally. But if you're running a multi-peptide protocol with daily or twice-daily injections across different sites, the visual map becomes a necessity, not a convenience.

Medication Support

Regimen covers the injectable medication categories that drive its user base: peptides, TRT, and GLP-1 medications. Within those categories, it offers specialized features — peptide reconstitution calculations, protocol scheduling that accounts for cycling and loading phases, and progress correlation that maps your outcomes against your protocol timeline. For someone running a BPC-157 and TB-500 stack or managing TRT with periodic bloodwork, these features address real workflow needs.

DoneDose supports a broader range of medication types. Any injectable — peptides, TRT, GLP-1, insulin, biologics like Humira or Enbrel — plus oral medications in the same app. This matters for people whose regimen isn't limited to one category. If you're on TRT plus daily oral medications, or managing a GLP-1 alongside metformin, DoneDose's unified tracking avoids the fragmentation of using multiple apps. The guide on combining oral and injectable medication tracking explains why a single system matters for adherence.

The dose calculator is worth addressing directly. DoneDose does not include one. If you need help calculating syringe volumes from vial concentrations — and many people do, especially with peptides — Regimen handles that in-app. DoneDose assumes you've already done that math (or used a testosterone dose calculator or similar resource) and focuses on the logging step.

Privacy and Data

DoneDose stores everything on your device. No account, no cloud, no server-side storage. Your medication history, site rotation data, and body metrics exist only on your phone. This is a deliberate design choice, not a missing feature — it means your health data can't be breached, sold, or subpoenaed from a server because it doesn't live on one.

Regimen's data handling practices should be reviewed on their current privacy policy at helloregimen.com. Cloud-connected features like progress correlation and smart reminders may involve server-side data processing, which brings the standard tradeoffs: backup capability and richer analytics in exchange for data leaving your device.

For people tracking peptide protocols or TRT — medications that carry social stigma in some contexts or that users simply prefer to keep private — on-device storage is a meaningful differentiator.

Price

DoneDose is free. Every feature, no subscription, no premium tier.

Regimen's pricing should be verified at helloregimen.com or on the App Store, as it may have changed since this comparison was written. Many injectable tracking apps use a freemium model with core features available for free and advanced features behind a subscription.

User Experience

Regimen's UX reflects its more complex feature set. The dose calculator, reconstitution tools, and progress correlation features add screens and configuration steps that simpler apps don't have. For users who need those features, the added complexity is justified — the alternative is doing those calculations externally and stitching together data from multiple sources. Regimen's blog content also suggests the team thinks carefully about the user education layer, which shows in how the app guides you through protocol setup.

DoneDose's UX prioritizes speed and simplicity. The daily workflow is: notification fires, open app, one tap to log dose, select site on body map, done. There's no calculation step, no analytics dashboard to navigate through — the app assumes you want to record what happened and move on with your day. The body metrics screen (weight, mood, appetite, energy) is available when you want to log context but doesn't interrupt the dose-logging flow.

For complex peptide protocols where you need the app to help you figure out what to inject, Regimen's richer interface earns its complexity. For day-to-day logging where you already know what you're doing and just need to track it reliably, DoneDose's simplicity is an advantage — fewer steps means fewer opportunities to skip the log.

Who Should Choose Regimen

Regimen is the right choice if:

• You need a built-in dose calculator for peptides or TRT
• Peptide reconstitution calculations are part of your workflow
• You want progress correlation that maps outcomes to your protocol timeline
• You're starting a new protocol and need help with scheduling and dose planning
• Smart, protocol-aware reminders are more valuable to you than visual site rotation
• You're primarily tracking peptides, TRT, or GLP-1 medications (not oral meds)

Regimen's specialization in the dose planning and calculation space fills a real gap. For someone who is new to self-injection protocols and needs guidance on how much to draw, it's genuinely helpful.

Who Should Choose DoneDose

DoneDose is the right choice if:

• Injection site rotation tracking with a visual body map is your priority
• You inject frequently (daily or more) and need detailed rotation management
• Your regimen includes both oral and injectable medications
• You already know your doses and need a fast, reliable logging tool
• On-device privacy with no account or cloud sync is important to you
• You want a free app with no feature restrictions
• You take medications beyond the peptide/TRT/GLP-1 categories

DoneDose is the stronger choice for the daily act of tracking. If your dose calculations are settled and your primary challenge is logging consistently, rotating sites properly, and keeping your entire regimen in one place, it's the more focused tool for that job.

Frequently Asked Questions
