Zepbound Tracker for iPhone
OptiPin is a private Zepbound tracker that turns a weekly injection into a clean, reviewable record. Log each dose, follow your titration ladder (2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg), rotate injection sites, chart your weight over the dose timeline, note side effects, and get a reminder when the next shot is due - plus a warning before a pen runs out. Everything stays on your device; no account, no cloud upload.

Zepbound is tirzepatide dosed for weight management - a once-weekly dual GIP/GLP-1 medication with a roughly five-day half-life, so each dose stacks toward steady state over about four to five weeks. That cadence is exactly why a tracker helps: a single missed or mistimed shot, or a titration step taken too early, is easy to lose track of in your head but obvious on a timeline. Tracking also lets you connect the things that actually matter to you - weight, appetite and side effects - to which week and which dose you were on, instead of guessing.
Notes apps and spreadsheets can hold a list of dates, but they can't remind you on the due day, rotate your injection sites, warn you before a pen empties, or plot weight against dose. OptiPin is built for exactly that.
What the OptiPin Zepbound tracker does
Already on a prescribed pen, or switching brands? OptiPin treats Zepbound, Mounjaro and Wegovy the same way, so you can track more than one GLP-1 - or move between them - in a single timeline. For the science behind the molecule - half-life, the SURMOUNT trials and the reconstitution math for compounded vials - see the tirzepatide reference.
Free dose tools for Zepbound
Calculators that pair with tracking - no app needed to use them:
- GLP-1 pen click chart - convert a prescribed dose into clicks and units on the Zepbound pen or vial.
- GLP-1 titration schedule - the 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg ramp laid out week by week.
- Reconstitution calculator - for compounded tirzepatide vials, turns vial size + water into exact syringe units.
- Half-life visualizer - see how once-weekly doses stack toward steady state.
One app for everything you're on
The real advantage of OptiPin is that Zepbound doesn't live in isolation. If you're also on TRT, a peptide, or a supplement stack, all of it sits in one place with a single timeline and one set of insights - instead of fragmented across a pen's own app, a notes file and your memory. That's the difference between logging a drug and actually seeing your protocol.

Is there an app to track Zepbound?
Yes - OptiPin. You log each weekly injection, follow the titration ladder, rotate sites, chart weight over your dose timeline, record side effects, and get reminders plus pen runout warnings. It's on iPhone, stores data on-device and needs no account.
Is the OptiPin Zepbound tracker free?
It's free to download and start tracking. Core dose logging and reminders are in the free tier; Premium adds CSV import/export and unlimited history.
Can it track my Zepbound titration schedule?
Yes. Set the 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg weekly ladder and OptiPin tracks which step you're on and when the next escalation is due. The schedule is whatever your prescriber sets - OptiPin records and reminds, it doesn't recommend a dose. See also the GLP-1 titration schedule.
Does it track weight loss alongside Zepbound?
Yes. Log weight and measurements (or read them from Apple Health) and OptiPin plots them over your injection timeline, so you can see how weight tracks against weeks on each dose.
Zepbound vs Mounjaro - does the tracker care?
Both are tirzepatide, so OptiPin tracks them identically; the difference is indication (Zepbound for weight management, Mounjaro for diabetes) - same molecule, same 2.5–15 mg ladder. Track either or both on one timeline.
