Best Peptide Tracker Apps in 2026: An Honest Comparison
A fair comparison of the peptide and GLP-1 tracking apps available in 2026 — TrackPep, Regimen, PeptIQ, Shotsy and others — by platform, compound support, calculators and price.
We build one of the apps on this list, so read this with that in mind. What follows is written to the same rule we use on our comparison pages: describe competitors with durable, defensible facts, never disparage them, and be specific about where someone else is the better choice. A comparison that a competitor's own team would call accurate is more useful to you and ages better.
How to actually choose
Most people pick a peptide tracker on the wrong criterion. Feature lists all look similar. In practice four questions decide it:
- Do you track one compound or several? GLP-1-only apps are simpler and often better if you genuinely only run one thing. They become frustrating the moment you add a second.
- Do you need it outside your phone? Several of the best-known apps are iOS-only. If you want to review a log on a laptop, that rules them out immediately.
- Do you need the dose maths built in? Reconstitution and syringe-unit conversion is where errors actually happen. An app that logs but does not calculate leaves you doing that maths elsewhere.
- What happens to your data? On-device storage, synced accounts and export options are genuinely different trade-offs. None is universally correct.
The apps
TrackPep AI
Ours. Web, iOS and Android under one account. Built multi-compound from the start, with reconstitution and syringe-unit calculators, body-map injection-site rotation, vial and BAC water inventory with expiry dates, and a private log you can export. Free tier covers 3 active compounds with 30-day history; Pro is $7.99/month or $34.99/year. Interface is available in 16 languages.
Choose something else if you only ever track a single GLP-1 on an iPhone and want the most established single-purpose app — you will not need most of what we built.
Regimen
One of the most feature-complete multi-compound trackers available, with a large compound library and advanced lab and biomarker overlay features. Runs on web and mobile. Free tier plus a subscription.
Choose Regimen if you want the deepest feature set, particularly advanced biomarker overlays, and you do not mind more complexity to get there. It is genuinely the most featured option in this category.
PeptIQ
An iOS app known for AI-assisted vial scanning and on-device data storage. Supports injection-site logging and includes calculators. Freemium.
Choose PeptIQ if you want AI vial scanning and you are happy for everything to live on a single iOS device. On-device-only storage is a real privacy advantage if that is what you are optimising for.
Shotsy
A polished, well-designed tracker focused specifically on GLP-1 medications — Ozempic, Wegovy, Mounjaro, Zepbound. iOS. Annual subscription.
Choose Shotsy if you track exactly one GLP-1, on an iPhone, and want a focused shot logger with a large existing user base. It does that job very well and does not try to do more.
Others worth knowing about
Several more apps appear regularly in this category, including Shotlee, PepTracker, PeptideKit and Smart Peptide Tracker. Coverage, platform and pricing vary and change often — check each current listing rather than trusting any roundup, including this one.
Quick comparison
| Platforms | Multi-compound | Built-in dose maths | Free tier | |
|---|---|---|---|---|
| TrackPep AI | Web, iOS, Android | Yes, by design | Reconstitution + syringe units | Yes — 3 compounds, 30-day history |
| Regimen | Web, mobile | Yes, large library | Included | Yes, plus subscription |
| PeptIQ | iOS | Yes | Calculators + AI entry | Freemium |
| Shotsy | iOS | GLP-1 focused | Not the core focus | Check current listing |
The honest summary
- Widest feature set: Regimen
- Best if you stay on iOS and want AI scanning: PeptIQ
- Best single-GLP-1 logger: Shotsy
- Best if you need web plus mobile, multi-compound, with the maths built in: TrackPep AI
If you are tracking one GLP-1 and nothing else, you do not need a multi-compound tracker and should pick the simplest thing that logs a weekly shot. The case for TrackPep starts when you have a second compound, or when you want to open your log on something other than your phone.
FAQ
Is there a free peptide tracker? Several apps have a free tier, including TrackPep and Regimen. Free tiers usually cap the number of active compounds or the length of history retained rather than removing core logging.
Do any peptide trackers work on Android? Yes, though fewer than on iOS. TrackPep and Regimen both run on Android; PeptIQ and Shotsy are iOS apps.
Can I use a peptide tracker on a computer? TrackPep and Regimen both offer web access. Most other options in this category are phone-only.
Which app has a reconstitution calculator? TrackPep, Regimen and PeptIQ all include dose maths. TrackPep also publishes its calculators as free web tools that work without an account.
Do these apps give medical advice? No, and you should be wary of any that appear to. Tracking apps record what you did and help with arithmetic. Dosing decisions belong with a licensed prescriber.
