Glpfy
The GLP-1 tracker that never sees your data.
No account. No cloud. Nothing leaves your phone.
Built around how a GLP-1 course actually goes
Not a generic habit tracker with a medication field bolted on. Every screen exists because something about this treatment is hard to keep track of on your own.
Estimated medication level
A one-compartment model built from published elimination half-lives shows roughly how much is still active, summing every dose you have logged. Semaglutide, tirzepatide, dulaglutide and liraglutide — labelled an estimate everywhere it appears, because it is one.
Daily coach
Protein, calorie, fibre and hydration targets calculated from your own details, turned into a short daily mission list — and safety warnings when what you have logged deserves one.
Next-dose countdown
Your injection day and time, counted down to the hour, with a reminder so a shifted schedule or a travel week does not turn into a missed dose.
Weight and progress
Log your weight and watch the trend rather than the daily noise — since you started, since your last dose increase, against the goal you set.
Meals without a food database
Log a meal by name and macros in seconds. Save the ones you eat often and re-log them with a single tap — no searching a database of 800,000 items for your usual breakfast.
Side effects, tracked over time
Record nausea, fatigue and the rest with a severity, so you can see whether that rough week follows every dose increase — and show your prescriber a pattern instead of a memory.
Clinician report
A clean summary of your doses, weight trend and side effects for your next appointment, instead of scrolling through an app in front of your doctor.
Export and erase
Take a full copy of your data whenever you want, and wipe it permanently when you are done. Both are one tap in Settings — no request form, no waiting on us.
The honest version fits in one sentence
Your health data is stored on your device and nowhere else. That is not a policy we promise to keep — it is how the app is built. There is no account system and no backend, so there is no copy of your weight, your medication or your notes for anyone to leak, subpoena or sell.
- No account, no sign-in. Nothing links the app to your identity.
- No health data leaves the device. Not your weight, doses, medication name, meals, side effects or journal entries.
- Never sold, never used for ads. By anyone, for any purpose.
- Anonymous usage data is optional. On Android you can switch off analytics and crash reporting in Settings, and switching it off stops collection rather than hiding it.
- No connections to other health apps. This version reads nothing from Health Connect or any other health store.
What we can and cannot see
| Data | Leaves your device? |
|---|---|
| Weight, doses, medication | Never |
| Meals, hydration, side effects | Never |
| Journal entries | Never |
| Which screens you open | If you allow |
| Crash reports | If you allow |
Optional analytics record that an action happened — “a dose was logged” — never what it was. See Data & deletion for the full breakdown.

Glpfy is not a medical device
It is a personal tracking tool. It does not diagnose, treat, cure or prevent any condition, it never recommends a medication or a dose, and it is not a substitute for advice from a qualified healthcare professional. Targets and estimated medication levels are approximations calculated from published formulas and typical half-lives — not measurements of your body.
Always talk to your doctor, pharmacist or prescriber before starting, stopping or changing any treatment. If you think you are having a medical emergency, contact your local emergency services. Read the full medical disclaimer.
Frequently asked
Which medications does it support?
Semaglutide (Ozempic, Wegovy, Rybelsus), tirzepatide (Mounjaro, Zepbound), dulaglutide (Trulicity) and liraglutide (Saxenda, Victoza), plus compounded semaglutide and tirzepatide. If your medication is not listed you can still log doses — the app simply will not draw an estimated level curve, because there is no published half-life to model.
How accurate is the medication level chart?
It is an estimate and is labelled as one on every screen it appears. It models elimination using typical published half-lives for the active ingredient, summed across the doses you logged. Real concentrations vary substantially between people, and nothing in the app is a measurement of your body. Do not use it to make a dosing decision.
Do I need an account?
No. There is no sign-up, no email, no password. The app works fully offline.
What happens to my data if I change phones?
Because nothing is stored on a server, your data does not follow you automatically. Export your data from Settings on the old device and import it on the new one. Your device's own backup system may also include the app's data, depending on your device settings.
Can I delete my data?
Yes, and instantly. Settings has an option that erases everything from the device permanently, and uninstalling the app removes it too. Since there is no server copy, we cannot recover it afterwards — and we cannot see it in the first place. See Data & deletion.
Is there an iOS version?
Not yet. Glpfy is live on Google Play today; Android and iOS are built from one shared codebase, so an iOS release with the same features is coming.
Track your course without handing over your data
No account to create, no server to trust — just open the app and start logging.
