Track Your Wegovy Weight Loss Journey
Log every injection, see your weight trend at each dose, and track side effects through all five titration steps.
Semaglutide (Wegovy) — Weekly Weight Loss Injection
Regimen is the Wegovy tracker app designed for people managing their weight with semaglutide. Wegovy has a five-step titration schedule over 16+ weeks — Regimen logs every dose change, tracks your weight loss at each step, and monitors side effects so you know exactly how your body is responding. Connect your Apple Health or Google Health Connect data and see clear correlations between your Wegovy doses and your actual results — 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. 4.9-star rating.
Wegovy works — but only if you stay consistent.
The biggest obstacles aren't the injections themselves:
Losing track of your 4-week titration windows and accidentally staying on a dose too long — or jumping up too fast
No clear way to see if your weight loss is actually trending down or just fluctuating day-to-day
Managing side effects without knowing if they correlate to your dose step, timing, or food intake
Dose with precision
Regimen handles the complex math so you don't have to. Two built-in calculators give you exact numbers every time.
Peptide reconstitution calculator
Input your vial size, bacteriostatic water volume, and desired dose. Regimen tells you exactly how many units to draw on your syringe.
mL dose calculator
Enter your prescribed dose (mg) and concentration (mg/mL) to get the precise injection volume. Perfect for testosterone and oil-based compounds.
Never miss a dose. Never miss a cycle.
Stay consistent with zero effort. Regimen supports every dosing schedule you could need, with smart reminders to keep you on track.
Every schedule you need
Daily · specific days · split-week · every X days · twice daily · as-needed. Injections, pills, creams, sprays. Your protocol, your way.
Cycle management
Set your cycle duration and get alerts when it's time to cycle off or begin again. No more mental math or calendar counting.
See what's actually working
Correlate every compound and dose change against real health data. Stop guessing which protocol is moving the needle.
Auto-sync from Apple Health & Google Health Connect
Weight, body fat, sleep, resting heart rate, and blood pressure flow in automatically. No manual logging required.
Track how you feel, not just what you measure
Log energy, sleep quality, cravings, and daily notes alongside your biometrics. See the full picture of how your protocol affects you day to day.
Correlate medications with health trends
Changed your TRT dose three weeks ago? See exactly how your weight, sleep, and heart rate responded. Every dose change is overlaid on your health charts.
Know what's in your system
See estimated concentration curves for your compounds in real time. Know if you're at peak, trough, or steady state without waiting for labs.
Pharmacokinetic modeling for 40+ compounds
Regimen uses half-life data to model absorption, peak levels, and decay for every dose you take. See how levels build up over multiple doses.
Peak, trough & steady state visibility
Understand where you are in your dosing cycle at any moment. See projected future levels based on your current schedule.
Why tracking Wegovy matters
5-step titration management
Wegovy's 0.25 → 0.5 → 1.0 → 1.7 → 2.4 mg schedule spans 16+ weeks. Regimen keeps you on track so you never miss a step-up or rush one.
Weight trend, not daily noise
Daily weight fluctuates. Regimen auto-syncs from Apple Health and shows your real trend so you can see the progress your scale might be hiding.
Progress photos that tell the story
Weight is just one metric. Side-by-side comparison photos let you see the body composition changes that the number on the scale can't capture.

Why people are switching to Regimen
"I was juggling my peptide schedule between a notes app and my calendar, and I was constantly stressed about missing a dose. Regimen fixed all of it. The reminders and calculator are essential."
Alex T., Bio-Optimizer
"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."

How we built the Wegovy tracker
Wegovy is a 5-step titration: 0.25, 0.5, 1, 1.7, then 2.4 mg/week, typically four weeks per step. Most of the work in tracking Wegovy isn't the math, it's noticing what shifts when the dose steps up. GI side effects often spike for a week after each escalation. Hunger patterns change. Energy moves. Sleep changes for some people. Those week-after-escalation patterns are what the tracker is designed to catch.
Regimen's Wegovy tracker is built around that step-up question:
- 5-step titration logger: each escalation logs as a dose change with the date. Your history shows exactly when you moved up each step, so you can pair side-effect spikes to specific escalations.
- Side-effect tracking across 50+ markers: nausea, vomiting, constipation, diarrhea, sulfur burps, the food-stuck feeling, fatigue, mood, sleep, energy, plus custom markers for anything else you want to track.
- Weight trend overlay: each dose change shows on the same chart as your weight, so you can see how each step-up affected the trajectory.
- Apple Health and Google Health Connect: weight, resting heart rate, sleep, and blood pressure pull in automatically if you have a wearable or scale connected.
- Lab tracking: HbA1c, fasting glucose, lipid panel, and any other markers you watch. Each lab pull plots on the dose timeline so trends are visible against the titration steps.
- Compounded semaglutide supported: if you're on compounded semaglutide instead of branded Wegovy, the calculator handles mg-per-dose tracking with concentration math for whatever your compounding pharmacy is using.
- Multi-compound support: most Wegovy users on Regimen also track at least one other compound (an oral medication, a peptide, supplements, HRT). The app handles them all together instead of forcing you into a GLP-1-only silo.

Frequently Asked Questions
How do I log Wegovy injections by pen and titration step?
Select your current Wegovy pen (0.25, 0.5, 1, 1.7, or 2.4 mg) and confirm the injection. The app stores the full titration history with timestamps, so when you step up, the previous dose moves into your timeline and your active dose updates automatically.
Can Regimen track Wegovy alongside compounded semaglutide?
Yes. Pen Wegovy logs by strength; compounded semaglutide logs by mg per dose since vial concentrations differ. Both flow into the same weight, side effect, and lab views, so a switch between branded and compounded never breaks your history.
Will Regimen pull in my weight automatically?
Yes. Weight, body fat, BMI, and resting heart rate sync via Apple Health or Google Health Connect. Your weight trend plots directly under your Wegovy dose timeline, so every titration step lines up with what your scale actually did.
What Wegovy 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 specific to your pattern.
How does Regimen compare to Shotsy, Glapp, or MeAgain for Wegovy tracking?
See the comparison table above. Short version: those apps are GLP-1-only logs. Regimen handles Wegovy alongside any other compound, models blood levels with published PK data, and gives you lab correlation on the free tier.
Can I track lab work like HbA1c or lipids on Wegovy?
Yes. Enter labs manually or import from a CSV. Each value plots on a long-term trend with your Wegovy dose history overlaid, so you can see whether your weight loss is moving HbA1c, ALT, LDL, and other markers.
Is there a free Wegovy tracker in Regimen?
Yes. The free tier covers one compound, including Wegovy, with full dose logging, side effects, weight sync, and lab tracking. Pro ($4.99/month) unlocks multi-compound stacks and the Signals pattern engine.
Does Regimen treat Wegovy and Ozempic the same way?
The underlying compound is identical (semaglutide), so the math and PK curves match. The difference is framing: the Wegovy view emphasizes weight trajectory and titration up to 2.4mg, while Ozempic surfaces HbA1c and glucose more prominently. Your data flows the same way either side.
Stop guessing. Start optimizing.
Your protocol deserves better than a notes app and a calendar.
