Log the dose.Pick the site on a body map. Weekmark suggests the next one in your rotation.
See the week.Every day after the dose has a number, D0 to D6. You always know where you are and when the next dose is.
Keep it to yourself.No account, no server. Your log is encrypted on your phone, and backups are files you keep.
A dose log should not need a subscription and an account.
Most people take these medicines for a season. Weekmark is built for that: one price, a log that stays on your phone, and calm screens that only log, remind and show.
“Another monthly fee, for an app I only need for a while.”
Weekmark is one purchase, or free. Never a weekly plan.“Why does a dose log want my email and a server?”
There is no account. Your log is encrypted on your phone.“The feature I used just moved behind a paywall.”
Free stays free. That promise is in writing, with a date.Everything you are taking, in one calm place.
Weekly shots, daily pills and compounded vials share one log. Each screen below is the real app.
Days since your dose, and what comes next.
Open the app and see where you are in the week, when the next dose is due, and which site comes next. The level curve is an estimate from published half-life, labelled reference only, with no target lines.

Your log stays on your phone.
No analytics, advertising or crash-reporting SDKs in the app. Nothing to sign up for, and nowhere for your data to go.
No account, no server
There is nothing to sign up for. We could not read your log if we wanted to.
Encrypted on device
The log is an encrypted database on your phone. Progress photos are encrypted too.
Backups you hold
A passphrase-protected file you save where you choose. Restoring is always free.
Quiet reminders
Turn off medicine names in notifications, so the lock screen only says “Dose reminder”.

Questions, answered.
Which medicines does it work with?
Weekly injections, daily pills and compounded vials. Dose schedules and site guidance are quoted from DailyMed for Zepbound, Mounjaro, Wegovy (pen and tablet), Ozempic, Rybelsus, Foundayo and Saxenda, and for Mounjaro, Wegovy and Ozempic also from the EMA (EU). You can also add a custom or compounded medicine, plus other things you take.
Does Weekmark tell me what dose to take?
No. Weekmark logs and reminds. It never suggests a dose. Always follow your prescriber.
What is the “estimated level” curve?
A reference picture built from each medicine’s published half-life. It is labelled as an estimate and has no target lines.
What happens when I change phones?
Make an encrypted backup (Pro) or export CSV (free), then restore or import on the new phone. Restoring a backup is always free.
When and where does it launch?
December 2026, on the App Store and Google Play, in English, German and French.
Why one price instead of a subscription?
Most people use these medicines for a season, not forever. Paying once fits that, and it means we never need to move features behind a paywall to keep the lights on.
Be first to know.
One email at launch, with the founder price. Nothing else.
