How MeAgain Tracks Your Tirzepatide Week
One Shot Log for Mounjaro, Zepbound, or Compounded
MeAgain logs each weekly Mounjaro, Zepbound, or compounded tirzepatide shot with its dose, time, and site. A reminder arrives on shot day and a countdown runs until the next one. If a shot is missed, the next-dose card shows it as overdue for 4 days, the late-dose window on both labels, then goes back to your normal schedule.
Dose History You Can Scroll Back Through
MeAgain saves the dose with every shot and dates each weight, symptom, and meal entry, so you can scroll back and see how one dose went before the next. Both labels start tirzepatide at 2.5 mg and move up in 2.5 mg steps, each after at least 4 weeks, to as much as 15 mg. With Premium, progress photos and Journey Cards record what the scale cannot. If you switch medications, your past logs keep the medication they were logged with.
Injection Site Rotation
MeAgain stores the site of each shot on a body map. Turn on alternating sides, and the app suggests the other side for the next shot, so rotation runs in the background. The Mounjaro and Zepbound labels name the abdomen and thigh for shots you give yourself, and the back of the upper arm when someone helps, and ask for a new site every dose. If a spot turns red or lumpy, write it in the shot's notes so you can point to it at your next visit.
A 0 to 10 Score for Each Symptom
MeAgain has 29 built-in symptoms plus any you add, each scored 0 to 10 and saved with the time. Nausea, diarrhea, vomiting, and constipation are among the most common side effects on both tirzepatide labels, and they often follow a dose increase. Since every entry is dated, a look back shows whether nausea faded a couple of weeks into a new dose.
Food Logging That Fits a Smaller Appetite
MeAgain logs meals by photo, barcode, voice, search, or quick entry and totals protein, fiber, and water against daily targets. Tirzepatide lowers how much people eat, so the work shifts to getting enough protein, fiber, and water. The Capybara home screen widget keeps those totals in view, which helps on days when a meal is easy to skip.
Your Estimated Tirzepatide Level
The MeAgain medication graph estimates your tirzepatide level from the shots you log. Tirzepatide has a half-life of about 5 days, so the level rises after each shot and tapers off before the next, which helps explain why appetite comes back near shot day. Log a late shot at the time you took it, and the curve moves with it. It is an estimate for context, not a measurement, and it does not recommend a dose.
Tirzepatide Basics: What to Know While You Track
Tirzepatide is a weekly shot made by Eli Lilly and sold under two brand names, each with its own FDA label. The Mounjaro label approves it together with diet and exercise to improve blood sugar in adults and children 10 and older with type 2 diabetes, and to lower heart risk in some of those adults. The Zepbound label approves it together with a lower-calorie diet and more physical activity to lower body weight and keep it off in adults with obesity, or with overweight and at least one weight-related health problem, and to treat moderate to severe obstructive sleep apnea in adults with obesity. The two schedules start the same way but differ after that: Zepbound moves to 5 mg after 4 weeks, while Mounjaro stays at 2.5 mg until your blood sugar needs more help.
Compounded tirzepatide is mixed by a pharmacy for one person's prescription. It is not FDA-approved, and its dose follows that prescription. MeAgain lists it as its own medicine, with extra dose options that compounded prescriptions often use. MeAgain logs doses in milligrams, so if your vial label gives units or milliliters, ask your pharmacy for the milligram amount.
Across both labels, the side effects seen most often include nausea, diarrhea, vomiting, constipation, indigestion, and stomach pain. In SURMOUNT-1, a 72-week trial of 2,539 adults with obesity or overweight, people on weekly tirzepatide 15 mg lost 20.9% of their body weight on average, against 3.1% on placebo.
Tirzepatide forms at a glance
From the current FDA labels. Every form is taken once a week.
| Form | Use | Start | Highest |
|---|---|---|---|
| Mounjaro, weekly shot | Type 2 diabetes, heart risk | 2.5 mg | 15 mg (10 mg for children) |
| Zepbound, weekly shot | Weight, sleep apnea | 2.5 mg | 15 mg |
Your prescriber chooses the brand, the dose, and when it changes. A missed shot can be taken within 4 days under both labels; after that, skip it and keep your usual day. This table summarizes the FDA labels for education only. It is not medical advice.

What Our Users Say
“I like how MeAgain makes it easy to log my food and keeps me updated on when it's time to take my Zepbound.”
“Love love this app. It has everything I need. From giving an estimate on how much Zepbound is in my blood to not having to enter every ingredient in a made-from-scratch meal. I'm sure it's an estimate but don't care!”
“I've been on MeAgain for about 3 weeks to help me stay on track with my protein, fiber and water needs while taking my Zepbound. I really like the ease of tracking foods and the fact that I can see my progress.”
“I really love this app and how easy it is to use for my food, water, Mounjaro weekly shot and everything else. The app is totally worth the cost and it's been perfect for me.”
“I am very happy with my purchase of the app. I recently had to stop my Tirzepatide shots per my doctor and the app helped me see how much of the Tirz was in my system during that break. I’m able to log any effects and other information to help me manage this medication and weight loss journey. However the best is Capy! I receive valuable information and compassion! Who would have thought it from an AI application! Very personal and customized experience and it’s invaluable to me. I trust this app and its founders. They care!”

Tirzepatide Tracker FAQs
What app reminds me when to take my tirzepatide shot?
MeAgain does. It reminds you on shot day and counts down to the next shot, and it logs each weekly tirzepatide shot with the dose, the time, and the site. The shot log, side effects, food, and weight are free, all in one app.
Can MeAgain track compounded tirzepatide?
Yes. Compounded tirzepatide is its own medicine in MeAgain, with the usual doses plus the in-between amounts compounded prescriptions often call for. When your prescriber changes the amount, update it and keep logging; past entries stay as they were.
Are there any tirzepatide specific apps?
Yes. MeAgain is the app built for people on tirzepatide. Mounjaro, Zepbound, and compounded tirzepatide each have their own dose list in the app, so a shot takes a few taps to log, and the reminder and late-dose window follow the same weekly rhythm. Mounjaro and Zepbound share the same dose numbers, so a log that moves from one brand to the other still reads clearly. 807K users track their GLP-1 in MeAgain, and it is rated 4.8 stars on the App Store.
What is the best app for tracking weight loss on tirzepatide?
MeAgain. It charts your weight trend over weeks and months as you weigh in on a regular schedule, while meals and symptoms are logged as they happen. With a premium subscription, take a progress photo every few weeks and let Journey Cards mark milestones, so a slow week reads as part of the longer arc.
What is the best app for tracking my tirzepatide progress?
MeAgain. Your weight trend, the dose of each shot, and every side effect sit in one dated log, so you can look back at how each step up went, on the scale and in how you felt. Premium adds progress photos and Journey Cards for what a number leaves out.
What app helps rotate tirzepatide injection sites?
MeAgain does. Pick the site each time you log a shot, and the body map keeps it. With alternating on, the app offers the other side next time. Both labels list the abdomen and thigh, plus the back of your upper arm if someone else gives the shot.
How to track my tirzepatide side effects?
MeAgain makes it three steps: pick the side effect, rate it 0 to 10, and see it next to your dose and shot day. It keeps a time-stamped log of each one. Choose from the built-in list or add your own as it happens, then line an entry up with a dose increase and talk it through at your next appointment.
What is the easiest way to track my food on tirzepatide?
MeAgain. Use whichever way is quickest at the moment: a photo, a barcode scan, voice, search, or quick add, and all five are free. Your protein, fiber, and water add up against your daily targets, and each meal sits next to your tirzepatide dose and side effects, so a day of small meals still shows what you got in.
