Mounjaro tracker app: track your weekly shots
For planning and record-keeping only — not medical advice. Your dose and schedule are set by your prescriber.
Yes, you can track Mounjaro without an app named after it. KeepAlong is a GLP-1 shot tracker app that works with Mounjaro: log each weekly shot, get reminded on injection day, keep site rotation and pen supply in one place — while the brand name stays where it belongs, on the pen.
KeepAlong — GLP-1 shot tracker & planning tools
Set tirzepatide and your current Mounjaro strength once — KeepAlong reminds you on shot day, keeps a running count from the doses you log, and puts days-to-next-shot on a home-screen widget, with a Live Activity while a shot is due.
The app is launching soon. The web tools on this site are free — no sign-up needed.
What's specific about tracking Mounjaro
Mounjaro is tirzepatide, a dual GIP/GLP-1 receptor agonist, FDA-approved in 2022 for type 2 diabetes. From a tracking point of view, three label facts do all the work — the dose ladder, the container format, and the storage window. All three come from the Mounjaro prescribing information (checked 2026-08-18).
The ladder has six strengths, 2.5 mg apart: 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg. The label starts at 2.5 mg for initiation, moves to 5 mg after 4 weeks, then allows 2.5 mg increments after at least 4 weeks on the current dose, to a maximum of 15 mg once weekly in adults and 10 mg in pediatric patients 10 years and older. The format is no longer a single choice: Mounjaro is supplied as single-dose pens and single-dose vials in all six strengths, and as multi-dose vials and a single-patient-use KwikPen that each carry four weekly doses, from 10 mg/2.4 mL up to 60 mg/2.4 mL. Either vial is drawn by hand — the label states the needle and syringe are not included — and the KwikPen takes a KwikPen-compatible pen needle that isn't included either. Storage then follows the container rather than the drug (all checked 2026-08-18). Each fact turns into something your log has to handle:
Up to six titration dates
Every 4-week step boundary is a calendar date your reminders have to move to — six strengths, so up to six dated starts.
Supply counts by container
A single-dose pen or vial covers one shot, a multi-dose vial or KwikPen covers four — that ratio is your refill math.
A second clock, 21 or 30 days
Out of the fridge at up to 86°F (30°C), a single-dose pen or vial runs 21 days; a multi-dose vial or KwikPen runs 30.
Tirzepatide also ships under a second name: the Zepbound tracker page covers the same molecule approved for weight management in 2023, in the same four container formats, and it carries a second indication Mounjaro's label doesn't — obstructive sleep apnea. Prefer the molecule-first view across both brands? That's the tirzepatide tracker page.
Set up the log for Mounjaro
Dates come first. Give the titration date planner your first-injection date and it returns the earliest label date for every step of the Mounjaro ladder — the dates your shot-day reminders should hang on. KeepAlong turns the same schedule into notifications and a home-screen countdown, and your prescriber's actual dates always win over the label minimums. Every strength on that ladder, and how Lilly's two tirzepatide labels differ, is laid out in the tirzepatide dosage chart.
Then the two habits that decay fastest. Rotation: the injection sites guide maps the abdomen, thigh, and upper-arm choices and why writing the spot down beats remembering it. Storage: when a pen or vial travels or a fridge fails, the fridge timer counts elapsed time against the label window that applies — 21 days for a single-dose pen or vial, 30 for a multi-dose vial or KwikPen.
If you're deciding which columns your log deserves beyond dose and date, what to track on GLP-1 is the short answer. And if you'd rather compare options first, the best GLP-1 tracker apps roundup includes when a plain calendar is honestly enough.
Frequently asked questions
Mounjaro and Zepbound are both tirzepatide — is tracking any different?
Mounjaro and Zepbound track identically: the same six-step ladder, the same 4-week minimums, and the same four container formats. Only the label indication differs. Mounjaro is approved for type 2 diabetes, Zepbound for weight reduction and for moderate to severe obstructive sleep apnea in adults with obesity (both labels checked 2026-08-18).
Why isn’t KeepAlong called a Mounjaro tracker app?
Mounjaro is Eli Lilly’s trademark, and apps that put someone else’s brand into their own name are trading on it. KeepAlong is an independent tracker that works with Mounjaro — the brand appears in your log because you take it, not in the app’s name or icon.
When is a Mounjaro tracker not worth it?
On a stable maintenance dose, same weekday every week, with refills on autopilot, a plain calendar reminder honestly covers it. A tracker starts paying for itself during titration — up to six date changes — or when you rotate injection sites, count remaining pens, or want weight and shot history on one screen.
Does the KeepAlong app calculate Mounjaro doses?
No. Dose decisions belong to your prescriber, and Apple’s guideline 1.4.2 restricts drug-dose calculators to manufacturers and medical institutions anyway. The math tools live on this website as free browser calculators; the app sticks to logging shots, reminding you on injection day, and keeping your history in one place.
