Track Your Semaglutide Routine
Log every dose, see your weight loss trend, and know exactly how your body responds at each titration step.
Semaglutide — Compounded & Brand GLP-1
Regimen is the best semaglutide tracker app for people who want more than a dose reminder. Log your Ozempic, Wegovy, or compounded semaglutide doses, track your weight loss over time, monitor side effects during titration, and see how your semaglutide is actually affecting your body composition, sleep, and energy. Regimen connects your doses to your health data — automatically synced from Apple Health or Google Health Connect — with half-life modeling sourced from published clinical studies and FDA prescribing information. Free — every feature unlocked for your first medication. No paywall, no trial, no credit card. Rated 4.9 stars on the App Store.
Compounded semaglutide adds a layer of complexity.
Brand pens are straightforward. Compounded vials are not:
Calculating the exact syringe draw from your vial concentration — and second-guessing the math every single time
Tracking how many doses are left in your vial and when you need to reorder before you run out
Trying to compare your progress on compounded semaglutide when most resources only reference brand-name dosing
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.
Every schedule you need

What Regimen Tracks for Semaglutide
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 semaglutide tracker
Semaglutide is the active ingredient in both Wegovy (branded for weight loss, 5-step titration up to 2.4 mg/week) and Ozempic (branded for type 2 diabetes, pens up to 2 mg/week), and it's also widely dispensed in compounded form. People run semaglutide for weight, glycemic control, or both, and many switch between branded and compounded forms over time depending on supply, insurance, or cost. The tracker is built to handle all three forms on one continuous timeline.
What that looks like in the app:
- Wegovy dose-step logger: log each titration step (0.25, 0.5, 1, 1.7, 2.4 mg/week) with the date you moved up.
- Ozempic click-to-dose logger: log by pen strength and number of clicks. The app converts to mg automatically.
- Compounded reconstitution calculator: for compounded semaglutide, enter the vial concentration and the units you draw, and the app converts to your actual mg dose. If concentration changes between vials, update it and the math recalculates.
- Switching between forms: branded to compounded, Ozempic to Wegovy, all on one continuous timeline. No need to start a new log when supply or insurance changes.
- Blood glucose logging: manual entry plus CGM data via Apple Health (Dexcom, Libre). Fasting glucose, post-meal spikes, and time-in-range trends plot against dose history.
- HbA1c trend chart: every lab pull plots on a long-term chart with your dose history overlaid.
- Side-effect tracking across 50+ markers: nausea, vomiting, constipation, diarrhea, sulfur burps, fatigue, sleep, mood, appetite, energy, plus custom markers.
- Weight trend overlay: dose changes show on the same chart as weight.
- Lab tracking: HbA1c, fasting glucose, lipid panel, hematocrit. Each lab pull plots on the dose timeline.
- Apple Health and Google Health Connect: weight, sleep, resting heart rate, blood pressure, and CGM data auto-sync.
- Multi-compound support: most semaglutide users on Regimen also track at least one other medication or compound. One app, one timeline.

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 semaglutide 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 calculate compounded semaglutide doses in syringe units?
Enter your vial concentration (mg/mL), the bacteriostatic water you added, and your target dose in milligrams. Regimen converts that to exact units on a U-100 insulin syringe and saves the recipe so you only do the math once per vial.
Can Regimen track branded Ozempic or Wegovy alongside compounded semaglutide?
Yes. Pen Ozempic and Wegovy log by strength and clicks; compounded semaglutide logs by mg per dose. Switching between branded and compounded mid-schedule keeps your weight trend, side effect history, and labs continuous.
Does Regimen handle split-dose semaglutide schedules?
Yes. Split dosing (half your weekly dose every 3.5 days, or daily microdosing) is fully supported. The PK model accounts for the actual injection cadence, so blood-level estimates and side-effect patterns line up with what you are really doing.
Can I log glucose and HbA1c on semaglutide?
Yes. CGM data (Dexcom, Libre) and fingersticks both log to the same view. HbA1c, fasting glucose, and time-in-range plot against your dose timeline so you can see whether titration is actually moving the numbers.
What semaglutide side effects can I log?
GI symptoms (nausea, vomiting, constipation, diarrhea, sulfur burps, reflux), plus fatigue, sleep quality, mood, appetite intensity, food aversion, and the food-stuck feeling. Custom markers cover injection-site reactions or anything else specific to your pattern.
How does Regimen compare to Shotsy, Glapp, or MeAgain for semaglutide tracking?
See the comparison table above. Short version: those apps are GLP-1-only logs. Regimen handles semaglutide alongside any other compound, models blood levels with published PK data, and includes lab correlation on the free tier.
Is there a free semaglutide tracker in Regimen?
Yes. The free tier covers one compound, including semaglutide, with full dose logging, glucose, side effects, weight sync, and lab tracking. Pro ($4.99/month) unlocks multi-compound stacks and the Signals pattern engine.
Does Regimen treat Ozempic, Wegovy, and compounded semaglutide identically?
The underlying compound is the same, so the PK math is identical. The difference is framing per view: Ozempic surfaces HbA1c and glucose, Wegovy emphasizes weight trajectory, and the semaglutide view stays neutral for compounded dosing. Your data flows the same way across all three.
Stop guessing. Start optimizing.
Your GLP-1 routine deserves better than a notes app and a calendar.
