Ozempic tracker app: your weekly pen, dose steps and injection sites in one place
Short answer: PepLevel is an Ozempic tracker app for iPhone, coming soon to the App Store. It reminds you on injection day, logs each weekly dose against the pen it came from, suggests the next injection site and keeps weight and side effects on the same timeline as your doses. The free version tracks one medication. It does not track blood glucose, so keep your meter or CGM app for that.
What makes Ozempic its own tracking job
In the UK, Ozempic is licensed for adults with type 2 diabetes. It is semaglutide, injected once a week on the same day, at any time of day. The patient leaflet even suggests writing your chosen weekday on the carton and the date on the carton each time you inject. That is a tracker, just a cardboard one that goes in the bin with the pen.
An Ozempic tracker app keeps that record and adds what a carton cannot: your current step, doses left in this pen, last week's site and how you felt afterwards.
The dose steps in the leaflet
The UK leaflet describes a stepped start. Your doctor decides if and when you move up, so treat this as the label's outline rather than your plan.
| Step | What the leaflet says |
|---|---|
| 0.25 mg once a week | The starting dose, for four weeks |
| 0.5 mg once a week | After four weeks your doctor will increase to this |
| 1 mg once a week | Your doctor may increase to this if blood sugar is not controlled well enough on 0.5 mg |
| 2 mg once a week | Your doctor may increase to this if blood sugar is not controlled well enough on 1 mg |
Each strength comes in its own pen, so a step change usually means a new pen as well as a new number.
The pen: four doses and a dose counter
The Ozempic pen is a pre-filled dial-a-dose pen, but it only lets you select one dose. According to the UK leaflets, an unused pen contains four doses at its strength, whether that is 0.25 mg, 0.5 mg, 1 mg or 2 mg. You turn the dose selector until the dose counter stops at your dose, and the leaflet is clear that you should not count clicks. The counter and the dose pointer are what show the dose.
A few details from the leaflet are worth tracking:
- Check the flow with each new pen, before its first injection only.
- After first use, the pen can be kept for 6 weeks below 30°C or in the fridge, so the date you opened it matters.
- Doses left. If the dose counter stops before your dose, there is not enough left for a full dose.
Late shots and changing your day
The leaflet says that if you forget a dose and it is 5 days or less since it was due, use it as soon as you remember. If it is more than 5 days, skip it and inject on your usual day. You can change your weekly day as long as at least 3 days have passed since your last injection. Both rules depend on knowing exactly when your last shot was. Ask your pharmacist if you are unsure.
Sites, weight and side effects
The leaflet names the front of the thighs, the front of the waist (abdomen) and the upper arm. Your diabetes review will also ask about weight and side effects, so dates matter there too.
What an Ozempic tracker will not do
PepLevel does not read or log blood glucose or HbA1c. If you test your sugar, your meter or CGM app remains the place for those numbers. PepLevel handles the injection side.
How PepLevel handles it
Add Ozempic during setup, pick your injection day and type in the step plan your prescriber gave you. PepLevel never suggests a step or changes one. It reminds you against the plan you entered, and the Today screen shows the current step and a countdown to your next shot.
Save your pen with its total amount and expiry, and set its dose control to fixed so the app follows the pen's own setting with no click maths. Each time you log, Log Dose is prefilled with the amount, time and a suggested site, and the dose is taken off that pen. Today warns you when supply is low, and a reorder reminder arrives 14 days ahead by default, which suits a repeat prescription.
The site rotation grid shows your suggested, recent and older sites, including thigh, abdomen and upper arm. Weight goes in kg, lb or stone. Side effects take a symptom, a severity from 1 to 5 and the dose they followed. Before a diabetes review, Prepare for appointment builds a one-page PDF of your medication, current step, recent doses, weight trend and side effects.
There is no account, your records stay on your iPhone and Face ID can lock the app. The free version covers one medication. Pro, for more than one, is £5.99 a month, £24.99 a year with a 7-day free trial, or £69.99 once for lifetime.
Common questions
Is there a free Ozempic tracker app?
PepLevel's free version tracks one medication, which covers a single Ozempic plan with reminders, dose logging, sites, weight and side effects. It is coming soon to the App Store for iPhone. Pro is only needed if you track more than one medication.
Can I track my Ozempic shots and blood sugar in one app?
Not in PepLevel. It tracks the injection side (doses, pens, sites, weight and side effects) and does not log glucose. Keep using your meter or CGM app for blood sugar, and bring both to your review.
How many doses are in an Ozempic pen?
The UK leaflets say an unused pen contains four doses at its strength. The dose counter stops early when less than a full dose is left. Logging each shot against the pen means you know which dose you are on before you pick it up.
