Zest (by Launchpoint Dev Inc.) is a new peptide tracking app. Its website shows a reconstitution calculator with a visual syringe, dose logging with an injection-site body map, reminders, vial inventory, a daily wellness check-in and a 69-compound research library with an AI assistant called Zest AI. As of October 31, 2026 its App Store and Google Play buttons say "coming soon", so it is not out yet.
Dose Track is a dose tracker for people who run more than one medication, with research peptides, GLP-1s, TRT and supplements, vials, blends and bloodwork in the same place. It is on iPhone and Android now.
Transparency note: Dose Track publishes this comparison. Everything about Zest below comes from its own website (home page, FAQ, download page and Consumer Health Data policy), because it has no App Store or Google Play listing yet, checked October 31, 2026 and linked under Sources. Apps change quickly, so check its current listing before deciding.
Dose Track is the better pick. It does everything Zest lists as its main features: a calculator, logging with site rotation, reminders, vials, a daily check-in, guides and an AI assistant. You can download it today, and it adds GLP-1s, testosterone and supplements, blends, estimated levels, lab results next to your doses and a Community. Zest is an OK alternative once it launches.

Based on each app's public listings and website as of October 31, 2026. A dash means the feature was not listed at the time, not that the app cannot do it.
Zest is built around research peptides. The reconstitution calculator turns the vial, water and amount you enter into a mark on a drawn syringe, and it works before you make an account. A calculation can be saved as a protocol, which then drives reminders and vial tracking.
Its app previews show logging in a couple of taps, with the injection site picked on a body map that suggests the next one, the vial the dose comes from, and what is left after it. Vials show a low warning before they run out. A daily check-in records energy, mood, sleep and appetite, and an insights screen shows doses taken, skipped and check-ins over 7, 30 or 90 days.
The research library lists 69 compounds by goal (recovery, weight, growth, cognitive and more). Compound pages show half-life, route and regulatory status, and Zest AI answers questions about them. Guides cover mixing a vial and injecting. Its site is clear that Zest does not recommend doses, and its FAQ says you can export or delete your data at any time.
Zest is not out yet. Its App Store and Google Play buttons said "coming soon" on October 31, 2026. It is still being built, so its feature list may grow.
Today its site does not list GLP-1s, testosterone, supplements, blends, estimated levels, bloodwork or a Community. Dose Track has all of these. The main features Zest does list (calculator, dose logging, site rotation, reminders, vials, daily check-in, research library, guides and an AI assistant) are all in Dose Track too.
Dose Track is on iPhone and Android now. Zest's store buttons said "coming soon" when we checked.
Dose Track is built for people running several medications at once: a research peptide next to a GLP-1, testosterone or supplements, each with its own schedule and its own estimated level, from a library of 800+ medications and supplements. Blends are logged as blends, so each compound in the vial is recorded and counted.
Vials and pens count down by the dose and warn you before you run out, and the reconstitution calculator works in the app and free on the web. Bloodwork goes in as a lab PDF or photo; markers stay next to your dose history. Pulse answers questions from your own log, and the Community is there when you want to ask other people. Dose Track records what you enter and does not recommend doses.
Research is built in. Of the 800+ medications and supplements, 428 have a research page: how the compound works, its safety, FDA status and references, and for most, the doses studied in research. Guides, an interaction checker and 650+ free compound pages on dosetrack.app sit alongside. None of it is a dose recommendation.
Both apps have a reconstitution calculator, log doses with injection sites, send reminders, track vials and warn when one runs low, keep a daily check-in, include a research library, guides and an AI assistant, and work with Apple Health and Health Connect. Neither tells you what dose to take.
Zest stores your protocols and history in a Zest account, which you create when you want to save a protocol. Its FAQ says it does not sell your health data, advertise against it or use your protocol records to train models, and it publishes a Consumer Health Data policy. Dose Track keeps records on your phone with no account needed, unless you turn on the encrypted backup, which only your password opens.
Zest has no App Store or Google Play listing yet, so we read its website on October 31, 2026: the home page, the FAQ, the download page and the Consumer Health Data policy. Features shown in its app previews are described as its website shows them; we have not used the app. Dose Track facts come from our own app. We did not use reviews to judge features. Dose Track publishes this page, so the framing is ours, but every claim about Zest can be checked at the links above. If something here is out of date, email hello@dosetrack.app and we will fix it.
