Track Your Ozempic Injections
Log every dose, monitor your progress, and see how Ozempic is affecting your health metrics over time.
Semaglutide (Ozempic) — Weekly GLP-1 Injection
Regimen is the Ozempic tracker app that goes beyond dose reminders. Log your weekly Ozempic injections, track how your weight and health metrics change over time, monitor side effects during titration, and see clear correlations between your doses and your results. Ozempic's semaglutide works best with consistent tracking — and Regimen makes that effortless, with half-life data sourced from published clinical studies and FDA prescribing information. Free — every feature unlocked for your first medication. No paywall, no trial, no credit card. Available on iOS and Android with a 4.9-star rating.
Ozempic is simple — until it isn't.
Most people start strong, then hit real friction:
Forgetting exactly which day you took your last dose — was it Tuesday or Wednesday?
Losing track of your dose schedule and when you're supposed to move up to the next pen strength
No way to correlate your weight loss stalls with dose timing, diet changes, or side effects
Dose with precision
Regimen handles the dose math so you don't have to, including compounded vial conversions.
Compounded dose calculator
Using compounded semaglutide or tirzepatide from a vial? Input your vial size, bacteriostatic water volume, and target dose. Regimen tells you exactly how many units to draw.
Never miss a dose. Stay on schedule.
Stay consistent with zero effort. Regimen supports weekly injections, dose-step changes, and any schedule your medication needs, with smart reminders that actually help.

Peak, trough & steady state visibility

Why tracking Ozempic matters
Dose schedule clarity
Ozempic steps up through 0.25, 0.5, 1.0, and 2.0 mg. Regimen tracks exactly where you are and when your next step-up is due.
Plateau detection
Weight loss stalls are common on semaglutide. With automatic Apple Health sync, you can see exactly when your progress slowed — and what changed.
Side effect timing
Nausea, fatigue, and appetite changes often follow predictable patterns relative to your injection day. Tracking helps you and your doctor optimize timing.
What Regimen Tracks for Ozempic
Why people are switching to Regimen
"I finally feel in control of my weight loss journey. The photo comparison feature is addictive. Seeing my progress next to the tracking data motivates me way more than just the number on the scale."
Sarah K., GLP-1 User
"Started Zepbound a few months ago and needed something to track my doses and weight. This app is perfect, reminders keep me on schedule, I can log my injections and see my progress all in one place. The progress photos feature is really motivating too."

How we built the Ozempic tracker
Ozempic comes in four pen strengths (0.25, 0.5, 1, and 2 mg), and the dose math is click-based: each click of the pen delivers a fixed amount, and the prescribed dose maps to a specific number of clicks. People on Ozempic for type 2 diabetes typically care about two things at once: how the dose is affecting their glucose control (A1c, fasting glucose, post-meal spikes) and how their body is handling the medication (side effects, weight movement).
Regimen's Ozempic tracker is built around both:
- Click-to-dose pen tracking: log each injection by pen strength and number of clicks. The app stores the full history so you can see exactly when you titrated up and how each step affected your glucose and weight numbers.
- Blood glucose logging: manual entry for fingersticks, plus CGM data via Apple Health if you're on a Dexcom or Libre. Fasting glucose plots on the same timeline as your doses.
- HbA1c trend chart: every lab pull plots on a long-term chart with your dose history overlaid. The point is to see whether each dose adjustment is moving the needle on A1c, not just to log a single number.
- Side-effect tracking across 50+ markers: nausea, vomiting, constipation, diarrhea, sulfur burps, fatigue, sleep, mood, energy, plus custom markers.
- Weight trend overlay: dose changes show on the same chart as weight so you can see how titration is affecting body composition alongside glycemic control.
- Apple Health and Google Health Connect: weight, sleep, resting heart rate, blood pressure, and CGM glucose data all sync.
- Multi-compound support: most Ozempic users on Regimen also track at least one other medication (metformin, an SGLT2, a statin, blood pressure meds). The app keeps the whole regimen in one timeline instead of forcing you into a GLP-1-only silo.
Your data stays private
Your health data is stored securely. We never share, sell, or monetize your information. What you track is your business, not ours.
See what's actually working
Regimen's Signals feature watches your check-ins and tells you the pattern it finds: your food noise tends to creep back around day 5 of your Ozempic week, or your energy dips as the dose wears off. It's not a summary of what you logged: it's what actually changed.

Frequently Asked Questions
How do I track my Ozempic doses with the click-to-dose calculator?
Log each injection by selecting the pen strength and the number of clicks. The app converts that to your actual mg dose and stores the full history. When you titrate up, the new dose replaces the old in your active log and your history shows exactly when the change happened.
Can Regimen track compounded semaglutide as well as branded Ozempic?
Yes. For branded Ozempic, you log by pen strength and clicks. For compounded semaglutide, you log by mg per dose since concentrations vary by compounding pharmacy. The dose calculator handles both.
Can I log my blood glucose readings in the same app?
Yes. Fingerstick readings can be entered manually. If you wear a CGM (Dexcom, Libre), glucose data syncs via Apple Health or Google Health Connect. Fasting glucose, post-meal spikes, and time-in-range trends all plot against your dose history.
Does Regimen track HbA1c over time?
Yes. Each lab pull plots on a long-term trend chart with your dose history overlaid, so you can see whether titration is actually moving your A1c numbers down (or holding them stable) across months.
What Ozempic side effects can I log?
Standard GI side effects (nausea, vomiting, constipation, diarrhea, sulfur burps), plus fatigue, sleep quality, mood, appetite, energy, and the food-stuck feeling. Custom markers cover anything else specific to your pattern.
How does Regimen compare to Shotsy, Glapp, or MeAgain for Ozempic tracking?
See the comparison table above. Short version: those apps are GLP-1-only and treat Ozempic mostly as a weight-loss tool. Regimen handles the T2D side (glucose, A1c, full lab integration) alongside the weight tracking, plus any other compound you might be on.
Is there a free Ozempic tracker in Regimen?
Yes. The free tier covers one compound, including Ozempic, with full dose logging, side effect tracking, glucose logging, and Apple Health sync. Pro ($4.99/month) unlocks multi-compound tracking and the Signals pattern engine.
Does Regimen treat Ozempic and Wegovy the same way?
The underlying compound is the same (semaglutide), so the tracking math is identical. The difference is framing: the Ozempic page surfaces the T2D-relevant stuff (glucose, A1c) more prominently, while the Wegovy page emphasizes weight trajectory. Your data flows the same way regardless.
Stop guessing. Start optimizing.
Your GLP-1 routine deserves better than a notes app and a calendar.
