Yes. Everything you log is free, forever: injections, weight and body values, meals, water, daily check-ins, symptoms, trends and the Visit Summary PDF. The only paid part is Arcy, the optional coach, at $9.99 per month or $59.99 per year after a 7-day free trial.
No. There is no account and nothing to sign up for. Your subscription, if you take one, belongs to your Apple ID and restores itself on a new phone.
In a database on your iPhone. WeekArc has no server for your health records. Your data is part of your own encrypted device backup, so a replaced phone restores it, and you can export an encrypted copy at any time.
Yes, and it is optional. You grant permission type by type in iOS, and you can change it any time in the Apple Health app. WeekArc can read values such as weight, body composition, water, nutrition and steps, and write entries you record such as water, nutrition and weight.
You can record any GLP-1 medication. The Estimated Medication Timeline is shown for medications with published pharmacokinetic data: semaglutide (Ozempic®, Wegovy®), tirzepatide (Mounjaro®, Zepbound®) and liraglutide (Victoza®, Saxenda®). Compounded medications are record-only. WeekArc is not affiliated with any pharmaceutical manufacturer.
No, and it never will. WeekArc records the dose you enter. It does not recommend, calculate or adjust doses, and it does not advise on a missed dose. Those questions belong to your prescriber.
An educational illustration drawn from your own dose records using published pharmacokinetic parameters. It is not a measurement of anything in your body, individual responses vary widely, and every figure behind it links to the prescribing information it came from.
An optional coach that reads the records you keep and talks with you about them: what a week looked like in your numbers, what today shows, what tomorrow's shot day means for today. Arcy describes your records; it never claims to know why something happened, never gives medical advice and never discusses doses.
Only when you switch it on and agree: today's numbers, the key facts of your journey (including the name of the medication you recorded), your last 28 days day by day, weekly summaries since your first record, and the messages you type. It goes through our server to OpenAI to generate the reply. Your name, dose amounts, injection sites and notes are never added to that summary. The privacy policy has the full list.
No. On GLP-1 medication the harder problem is eating enough, so WeekArc keeps protein, fiber and water visible instead of a calorie budget. There are no red numbers and no “you went over” warnings.
Yes. WeekArc imports a CSV of past records and exports everything at any time. Your history is never locked behind a subscription.
Not yet. WeekArc is an iPhone app today; Android is planned for a later release.
No. It is a personal record-keeping and progress app for tracking and educational purposes. It does not diagnose, treat or provide medical advice, and it is not a substitute for your healthcare provider.
