PeptIQ and Dose Track both aim at people who take their peptide protocols seriously, but they emphasize different things. PeptIQ leans into education and reference content alongside tracking; Dose Track leans into pharmacokinetic precision and on-device privacy.
Transparency note: Dose Track publishes this comparison. We describe PeptIQ fairly from its public listing and website — confirm current features and pricing on its own page before deciding.
If you are still learning the reasoning behind a protocol and want reference material next to your log — plus a browser you can open on a laptop — PeptIQ is a sensible pick. Choose Dose Track if precision is the priority: half-life-based level modeling across 600+ compounds, and health data that never leaves your device.

PeptIQ pairs tracking tools with a strong educational library, so you can learn the reasoning behind a protocol while you log it. It's available on iOS and Android with web access, which makes it a good pick if reference content and guidance matter as much as the tracking itself.
Dose Track is the only one of the two that models true pharmacokinetics — every dose is charted as a decaying exponential against the compound's calibrated half-life and Tmax, so you see your actual plasma level between injections instead of just a log of dates. It ships with 600+ compounds, parses bloodwork PDFs on demand, rotates injection sites automatically, and keeps all health data on-device — nothing is sold or stored on a server. It runs on both iOS and Android.
These two apps answer different questions, and the useful thing is to work out which question you are asking.
If you are early on and the uncertainty is what should I be doing — which compound, what dose, how long a cycle, why — then reference material next to your tracker is worth more than a more accurate chart. Precision about the wrong protocol is not progress, and PeptIQ's library is built for exactly that stage.
If the uncertainty is 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 — then modeling is the thing that answers it, and educational content will not. Dose Track is built for that stage.
Most people move from the first question to the second. That is a reasonable moment to reassess which app fits, and there is nothing wrong with having started somewhere else.
These two overlap more than most pairs in this category. Both run on iOS and Android, both include a reconstitution calculator, both track vials and expiration, both handle injection-site rotation, and both do something with bloodwork. If you are choosing on the basic checklist alone, either will serve.
The split is one of emphasis. PeptIQ puts guidance around the tracking. Dose Track puts modeling underneath it.
The web app is also the honest counterweight to Dose Track's privacy claim. Browser access means your data lives on a server so it can reach the browser — that is not a criticism, it is the trade every web app makes. Dose Track keeps health data on-device and syncs through your own private Apple or Google account, which is what makes it private, and equally what makes it 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.
Choose PeptIQ if you want a learning-forward experience with web access. Choose Dose Track if your priority is pharmacokinetic accuracy, a 600+ compound library, and fully on-device privacy for sensitive health data.
