GLP Journal — Your whole course, one journal

Your whole course, one journal.

The injections you perform, your weight, how you feel — recorded quietly, kept on your phone. The journal keeps the record. The decisions stay with you and your clinician.

Coming soon on the App Store No account. Your journal stays on your phone. Free to start.

An estimate that calls itself an estimate.

GLP Journal draws a relative level curve from one constant published in each medication's prescribing information — the half-life. It is an informational estimate, never a measurement: every screen that shows it says so, and the methodology behind it is one tap away.

“How is this estimated?”

A journal, in the plain sense of the word.

Open, log, close. A shot takes two taps to record; weight and a short check-in take a few more. Reminders follow the plan you set — with a quiet default wording that says nothing sensitive on a lock screen.

Entries survive restarts, phone migrations and your worst Mondays.

What it will never do.

It never proposes a dose, an interval or a schedule. You record what your clinician prescribed. Nothing is calculated for you.

It never grades your week. Statistics describe what you logged — in past tense, without verdicts.

It never diagnoses anything. When a pattern seems worth attention, it says exactly one thing: this is worth discussing with your doctor.

It never sends your journal anywhere. There is no server of ours and no account. What you write — doses, weight, side effects, check-ins — stays on your device. Measurement SDKs report anonymous app events and device identifiers for attribution; none of your entries is ever among them.

Your data stays yours.

Stored on your device. No account required. What you write is never collected — the app does measure how it is used, and the privacy policy says exactly who receives what.

journal entries→ a local database on your phone. Deleting the app deletes the data.

iCloud sync · optional→ your own private iCloud database. Only you can read it; we can't.

Apple Health weight→ stays on the device. Read with your permission — never uploaded, not even to iCloud.

app events · device identifiers→ our measurement partners. Which screen opened the paywall, whether a subscription was bought — so we can tell what brought you here. iOS asks first; decline and no advertising identifier is used.

anything you write→ nowhere. No server of ours, and no dose, weight, side effect or check-in is ever part of the above.

Most trackers end at the last shot. GLP Journal has an Off-Ramp mode for the phase your clinician plans after the course: the journal keeps observing weight and how you feel, so the conversation with your doctor is grounded in your own record — not in memory.
