Best Peptide Tracker Apps

Pep AI is probably the closest competitor to Peptides AI, at least as far as the major names in this industry go.

While most peptide trackers focus on GLP-1s, Pep AI was designed to “cover more ground”, so to speak. You’ll find features that feel immediately familiar if you’ve ever spent any amount of time managing multiple compounds, rotating stacks, or simply trying to keep track of half-used vials in your fridge.

What's strongest about Pep AI is how it handles organization. It’s essentially all about inventory management, protocol tracking, and keeping a detailed record of your peptide use. All of that can be very helpful for people who are running multiple compounds at the same time, but it will definitely suit individual peptide users, as well.

A lot of scientific research has demonstrated that reminders can significantly improve adherence across a wide range of health interventions^[2]. Pep AI features that, as well - you can set up reminders (in the form of push notifications) for your next dose, which will ensure that you remain consistent with your protocol.

Another added bonus for users who are a little more data-driven in their peptide use is that Pep AI also has bloodwork tracking capabilities. Seeing lab markers in addition to dosing information helps create a more complete picture of how you’re doing.

Key Features

While Pep AI doesn’t provide the same level of in-depth health analysis as Peptides AI, it’s still considered to be one of the better peptide tracking apps available today, especially for enthusiasts taking multiple compounds with complex dosing schedules.

Not all peptide users are running some elaborate stack of compounds.

In fact, many individuals searching for the best peptide tracker app are primarily on GLP-1s, such as semaglutide or tirzepatide, and want an easy way to track their progress and usage.

That’s where MeAgain comes in.

It’s a more lifestyle-oriented app, somewhat similar to Longeviters’ very own Peptides AI. MeAgain pairs compound tracking with nutrition & weight-loss insights, meal logging, and habit-building tools for GLP-1 users.

The app also has tools for tracking progress, so users can see how their weight, body measurements, photos, and other markers change over time.

That being said, MeAgain is powerful in tracking health markers, but it’s not the most powerful peptide tracking app on the market. If you use multiple different peptides, want to track & manage inventories, or follow advanced longevity protocols, you may find yourself wanting some more specialized functionality.

Key Features

In short, MeAgain is more of a lifestyle app than most others on this list. It may not be the best peptide tracker app for advanced users, but it’s one of the more useful options for people who want to combine compound tracking with nutrition, habit building, and long-term weight loss.

Shotsy is one of the more recognizable names in the GLP-1 tracking app space, and for good reasons.

The app has one of the cleanest user interfaces out there today and is very good at helping users track their peptide schedules, injection history, side effects, and progress over time. If you’re looking for a peptide tracker app iOS, Shotsy will almost certainly be near the top of the list.

In fact, a lot of people find out about peptide tracking apps through Shotsy.

The app was originally built around the GLP-1 drugs like Ozempic, Wegovy, Mounjaro, and Zepbound. Shotsy is not trying to be a one-stop shop kind of thing, but is rather focused on helping users understand how their compound use relates to symptoms, appetite changes, weight loss progress, and overall treatment adherence.

You also get visual graphs from Shotsy that estimate how much of the peptide is still active in your system as time goes on. For those on long-acting GLP-1s, this can be surprisingly informative. It allows you to see the ups and downs in between injections, which could lead to a better understanding of why some things may feel more or less intense on some days.

Most basic trackers don’t do that.

The app also syncs with Apple Health, so users can automatically link weight measurements and other health data. This is a much smoother experience than having to enter data manually every day.

Shotsy is, however, more of a GLP-1 tracking app than a general platform for peptide management. The feature set may be somewhat limiting for users running compounds like BPC-157, TB-500, CJC-1295, Ipamorelin, MOTS-c, or other, similar peptides.

Key Features

Shotsy is certainly one of the best iOS peptide tracker app options available today. Although it doesn’t have some of the more advanced peptide-specific features seen in higher-ranking apps, it’s still a great choice for GLP-1 users.

Some apps strive to be all-in-one health platforms. Others concentrate on doing fewer things well. PeptIQ falls into the latter group.

The app is designed to allow users to monitor peptide protocols, wellness metrics, and progress without overwhelming users with too many features. It doesn’t have the in-depth analysis that Peptides AI and similar apps do, but it’s a simple experience that many will enjoy.

The interface is quite clean, and the learning curve is a good deal lower than some of the more feature-rich options. Users can log peptide use, follow their protocol, monitor body measurements, and track their health journey, all with the help of advanced AI.

Consistency and progress tracking are the ideas that PeptIQ is built around, and thus, its main features are centered around that.

However, the app does have limitations. If you’re an advanced peptide user, you might miss having a dedicated calculator. If you run multiple compounds at once, you might also enjoy the deeper organizational features of Peptides AI or Pep AI.

Key Features

PeptIQ is an easy way to track peptides - it might not be the best peptide tracker app, but it’s a good choice for users who want simplicity and ease of use.

One thing that often gets missed in peptide conversations is consistency.

We spend countless hours researching compounds and optimizing doses. But many enthusiasts struggle with the one most basic requirement of all - simply sticking to the plan consistently.

Regimen is a “free health tracking app built for people who take injectable medications” - peptides and similar. It’s “purpose-built for injection protocols”, meaning all of its core functionality revolves around just that - injectables and their tracking.

The app’s interface is intuitive and rather straightforward to use, although it does contain a lot of information that can scare newcomers away. Regimen doesn’t require users to delve deep into analytics if they don’t want to, but core features like a reconstitution calculator or scheduling are there when you need them.

Even though the company behind the app markets it as a replacement for Google Sheets or notes, newbies might be inclined to either find an app that’s easier to get into, or one that supports more features. Using multiple apps to track your peptide stack, weight loss, and fitness goals can be a pain - most users would prefer to do so in a single platform.

To be fair, that’s less of a criticism towards Regimen, and more so a point that this app might not suit everyone’s wants and needs. It really just depends on your personal goals and peptide knowledge level!

Key Features

All in all, Regimen is certainly an app worth checking out, if none of the other names on this list fit your needs!

Of all the apps I’ve talked about on this list, PepTracker is one of the easiest entry points for people new to peptide tracking. The app is all about the basics - recording doses, keeping track of injection history, and scheduling reminders.

That might not sound very exciting, but there's something to be said about simplicity.

There are many users who start looking for the best free peptide tracker app because they are not yet sure how much they will use the software. They want something better than a notes app, but they don’t need advanced analytics or AI-powered insights.

PepTracker is kind of in that niche.

The interface is pretty simple, so you can get started quickly without having to spend much time learning the platform. Users can develop protocols, record injections, and view historical data with little setup.

On the flipside, PepTracker doesn’t have the extensive features of many of the best peptide tracker apps on this list. There are no fancy protocol analyses, body composition trackers, or built-in peptide calculators.

Key Features

If you want a lightweight peptide tracking app without a steep learning curve, this is still a perfectly reasonable option.
