Ozempic tracker app: log shots, pen doses, and weight
For planning and record-keeping only — not medical advice. Your dose and schedule are set by your prescriber.
Tracking Ozempic means keeping three counts at once: which day this week's shot lands, how many doses are left in the multi-dose pen, and how far that pen is into its 56-day in-use window. KeepAlong is an independent tracker — not a Novo Nordisk product — built for exactly this kind of weekly schedule.
KeepAlong — GLP-1 shot tracker & planning tools
A reminder on shot day, a home-screen widget counting down to your next dose, and weight synced from Apple Health or Health Connect — the moving parts of a weekly routine, kept in one place.
The app is launching soon. The web tools on this site are free — no sign-up needed.
What's specific about tracking Ozempic
Ozempic is Novo Nordisk's brand of semaglutide, FDA-approved in 2017 for type 2 diabetes and injected once a week. Since 2026 the same brand name also covers a daily tablet, so one distinction comes first: this page is about the weekly injection. If you take Ozempic tablets, the rhythm is daily and the strengths are different — Ozempic pill vs injection compares the two forms, and the weekly tools here do not apply to them. Two facts from the injection's FDA prescribing information (checked 2026-08-18) decide what a log for it actually has to hold — and both are about the pen, not the molecule.
First, the pen is multi-dose. One pen carries several weeks of injections, and the label says to attach a new needle for every shot — NovoFine Plus 32G 4 mm needles travel in the carton, six with the 2 mg pen and four with the 4 mg and 8 mg pens. All three pens hold 3 mL; how many shots that is depends on which presentation you were dispensed and which dose you're on:
| Presentation | Delivers doses of | Weekly shots it holds |
|---|---|---|
| 2 mg / 3 mL pen | 0.25 mg or 0.5 mg | Four at 0.25 mg plus two at 0.5 mg (starting schedule), or four at 0.5 mg |
| 4 mg / 3 mL pen | 1 mg | Four at 1 mg |
| 8 mg / 3 mL pen | 2 mg | Four at 2 mg |
| Single-dose prefilled syringe | 0.25 mg, 0.5 mg or 1 mg per 0.5 mL | One — the syringe is discarded after it |
That last row is the odd one out, and it removes the arithmetic rather than changing it: the label also lists single-dose prefilled syringes at 0.25, 0.5 and 1 mg per 0.5 mL, four to a carton (checked 2026-08-18). One injection empties one syringe, so there is nothing to count inside it and no 56-day pen clock to run — the label keeps a syringe refrigerated, with up to 28 days allowed at 46–86°F.
Second, a started pen is on the clock. From the first injection, the label gives a pen 56 days — kept at room temperature (59–86°F) or back in the fridge, the same clock runs either way. A pen can reach day 56 with doses still inside it, which is why the first-use date deserves to be written down the moment a new pen comes out.
Together that pushes Ozempic tracking toward pen arithmetic instead of plain shot-counting: doses remaining in the current pen matter in a way they never do with single-dose autoinjectors, and every pen needs its own 56-day timer running alongside the weekly shot rhythm. Refills follow the same arithmetic — doses left plus the day count tell you when the next pen actually needs to be in the fridge. The dose ladder itself is short: 0.25 mg for four weeks, then 0.5 mg, with 1 mg and 2 mg as further steps only if prescribed, each held at least four weeks.
The molecule isn't what makes this page specific: Wegovy is the same semaglutide, mostly in single-dose devices and with a longer five-step ladder, so its tracking job looks different — the Wegovy tracker covers it. What the two products share at molecule level lives on the semaglutide tracker page.
Set up the log for Ozempic
Dates first. Put your first-injection date into the titration date planner: it converts the label's four-week minimums into the earliest calendar boundary for each step, and the dates your prescriber then confirms are the ones worth reminders. The day each new pen gets its first shot, start its 56-day count in the fridge timer — one timer per pen, not per shot. The full ladder, including which strengths the label treats as maintenance, sits in the semaglutide dosage chart.
One supply line is easy to misjudge. Needles are not a separate errand at the start: NovoFine Plus 32G 4 mm needles come in the carton — six with the 2 mg pen, four with the 4 mg and 8 mg pens (checked 2026-08-18) — enough to cover the injections each pen holds. One needle per shot still means the count moves on its own schedule, and the label allows compatible needles up to 8 mm if you buy extras — GLP-1 pen needles covers what fits, and sharps disposal covers where they go afterwards.
Then the weekly entry: dose, injection site, weight. Sites rotate through the same three zones as any weekly GLP-1 — abdomen, thigh, upper arm — mapped in the injection sites guide, and what to track on GLP-1 sorts the optional extras from the core. Paper can hold all of these numbers; the KeepAlong GLP-1 shot tracker app exists for what paper can't do — remind you on shot day, count down on a home-screen widget, and pull weight from Apple Health or Health Connect on its own.

Frequently asked questions
How do you track how many doses are left in an Ozempic pen?
Ozempic pen doses are counted from the number the label prints for that pen, not by dividing milligrams. The 8 mg/3 mL pen holds four 2 mg shots, the 4 mg/3 mL pen four 1 mg shots, and the 2 mg/3 mL starter four 0.25 mg doses plus two at 0.5 mg. Subtract one per logged shot.
Does the 56-day Ozempic pen timer depend on the fridge?
No. After first use the label allows either storage — room temperature at 59–86°F or refrigerated — and the same 56-day clock runs in both. So the date worth recording is first use, one timer per pen; putting the pen back in the fridge doesn’t pause or reset anything.
Is tracking Ozempic different from tracking Wegovy?
Yes, mostly because of the device. Most Wegovy presentations are single-dose — one pen or one syringe per shot — so supply is counted in whole units per strength, its four-dose FlexTouch pen being the exception. Every Ozempic pen is multi-dose, so you count doses remaining inside the pen and watch its 56-day in-use window.
When is an Ozempic tracker not worth it?
On a stable maintenance dose, injected the same weekday, with pens finishing on a predictable rhythm, a calendar reminder honestly covers it. A tracker starts paying off when titration dates, injection-site rotation, and per-pen 56-day windows stack up — three counts a calendar can’t hold at once.
