PeptIQ and Dose Track both aim at people who take their peptide protocols seriously, and on the core features the two overlap a lot. PeptIQ adds a web app. Dose Track adds research pages for 428 compounds within its 800+ medications and supplements, level modeling for each medication it models, bloodwork next to your doses, and privacy by default.
Transparency note: Dose Track publishes this comparison. Everything about PeptIQ below comes from its App Store and Google Play listings and its website, checked October 31, 2026 and linked under Sources. Apps change quickly, so check its current listing before deciding.
Dose Track is the better pick for most people: research pages for 428 compounds within 800+ medications and supplements, level modeling, bloodwork next to your doses, and health data on your phone by default with a backup only your password opens. PeptIQ is worth a look if you want its MCP connector for AI assistants or its iMessage assistant.

PeptIQ pairs tracking tools with peptide profiles and a glossary. Next to that it has a reconstitution calculator, site rotation, vial and expiry tracking, bloodwork upload, and a half-life tracker. Your data can stay on your device or sync across your own devices.
It's available on iOS and Android and as a web app at app.peptiq.io, so you can also use it on a laptop. It is rated 4.7 from 952 ratings on the App Store and 4.4 from 718 on Google Play.
Both apps chart levels from half-life. Dose Track charts every dose as a decaying exponential against the compound's calibrated half-life and Tmax, so you see your estimated level between injections instead of just a log of dates, and it does that across an 800+ medications and supplements library, so GLP-1s, testosterone esters and peptides can sit on one timeline. It parses bloodwork PDFs on demand, rotates injection sites automatically, and stores health records on your phone, with no account needed. Data only leaves it for features you choose, like AI answers and lab reading, and nothing is sold. It runs on both iOS and Android.
Both apps put reference material next to the tracker. PeptIQ has a peptide library with profiles and a glossary. In Dose Track, 428 of the 800+ medications and supplements have a research page: how the compound works, its safety, FDA status and references, and for most, the doses studied in research. A Learn section adds guides, an interaction checker and a stack finder, and dosetrack.app has 650+ free compound pages. None of it is a dose recommendation.
Dose Track also answers is what I'm doing actually working: whether you have reached steady state, whether a schedule change moved your trough, whether a bloodwork result lines up with where your levels were that week. PeptIQ's half-life tracker answers part of this too; Dose Track models levels for the medications in its library and shows bloodwork next to your dose history.
These two overlap more than most pairs in this category. Both run on iOS and Android, both include a reconstitution calculator, both chart levels from half-life, both track vials and expiration, both handle injection-site rotation, both do something with bloodwork, and both can keep your data on your device.
Dose Track goes further on research depth, level modeling and privacy. PeptIQ also has a web app; Dose Track is a phone app that keeps health data on your phone by default.
PeptIQ also has a web app. To reach a browser, your records have to be synced somewhere; PeptIQ lets you choose between keeping data on your device and syncing it across your own devices. Dose Track keeps health data on your phone by default, with an optional backup encrypted with your password, which is also why it is phone-only.
Feature rows come from each app's public App Store or Google Play listing and its own website, checked at the date noted under the table. A dash means a feature was not advertised at the time of writing — not that the app cannot do it, and not that it will not be added. Dose Track publishes this page, so treat the framing as ours and the facts as verifiable: every claim about the other app can be checked on its own listing, and we would rather you did.

Dose Track is the recommendation for most people: research pages, level charts across an 800+ medications and supplements library, and privacy-first design that keeps sensitive health data on your phone by default. PeptIQ is worth a look if you want its MCP connector for AI assistants or its iMessage assistant.
