Start Tracking Your Tirzepatide
Quick answer
Shotsy is a tirzepatide tracker app that works with every form of the medication: Mounjaro, Zepbound, and compounded tirzepatide with custom dose amounts. It logs your weekly shot and injection site, tracks side effects and weight, estimates your medication level between doses, and exports PDF reports for your doctor. Core features are free on iPhone and Android, rated 4.8 stars from 29,000+ App Store ratings.
Why tirzepatide users track
One molecule, several forms
Tirzepatide comes as two brand-name weekly injections and as compounded formulations with custom amounts. A tracker has to fit your exact regimen, not just a preset brand menu. Shotsy handles preset brand doses and custom dose amounts alike.
A weekly shot is easy to lose track of
Tirzepatide is taken once every seven days, and life gets busy. A missed or late dose changes how you feel for the rest of the week. Shotsy's reminders and countdown widgets keep shot day visible so it never sneaks up on you.
Side effects follow patterns
Nausea, fatigue, and appetite changes often cluster in the days after an injection or a dose increase. Logging symptoms alongside your shot history reveals those patterns instead of leaving you guessing.
Appetite shifts across the week
Tirzepatide levels rise after your shot and fade toward the end of the week, which is why hunger and food noise can return before your next dose. Seeing your estimated level explains those shifts and helps you plan around them.
How Shotsy tracks your tirzepatide journey
Estimated tirzepatide levels between shots
Using published pharmacokinetic data for tirzepatide, which has a half-life of about five days, Shotsy charts how your estimated medication level rises and fades between doses. The chart is an estimate for context, not a measurement, and it can display multiple medications at once if you ever switch.
Progress charts by dosage
Shotsy breaks your weight trend down by dose, so you can see how your body responded at each amount, including custom amounts. No other GLP-1 tracker offers charts this detailed.
Injection site rotation
Choose the injection sites you use and Shotsy rotates them for you automatically. If you can never remember where your last shot went, Shotsy always knows which site is up next, and it charts your progress by injection site too.
Side effects tied to your dose timeline
Track nausea, constipation, fatigue, and more, with severity and notes. Because symptoms sit on the same timeline as your shots, you can spot exactly what follows a dose change.
Everything else your journey needs
Weight, protein, water, and calorie tracking with Apple Health sync, a maintenance mode for life at goal weight, a shareable GLP-1 Journey Recap, and PDF reports you can hand to your provider.
What tirzepatide users say about Shotsy
Verbatim five-star reviews from Shotsy's public App Store listing.
★★★★★
Great tracking app!
“Shotsy is super helpful for tracking my tirzepatide injections. It’s easy to use and navigate, and I love all of the data. It’s also helpful to see how much medication (estimated) is in my system at any point, and I’ve been able to notice patterns in my weight loss (injection site, time of day, etc). I did invest in the paid version to support the developer, but when I used the free version it also provided plenty of information. I’ve used this app for 8 months now and haven’t had any issues!”
★★★★★
Very Helpful
“I have been using this for several weeks and find it to be a useful tool in my weight loss. I love being able to see how much tirzepatide is still in my system as the week progresses. When stepping up a dose I am able to clearly see as the amounts build up. I am able to keep track of shot locations and my weight for a better overall picture.”
★★★★★
Better than my memory!
“Using Shotsy from the very start of my Tirzepatide journey was a smart decision. The app helps me remember which part of the body I last injected the shot. It also tracks the number of weeks, average weight loss per week, total weight loss, and BMI. Without Shotsy, I often forget how much I weighed on the previous shot day. That happens because I weigh myself one or two times between shots so I tend to remember the wrong amount. At least twice I was surprised when I entered my shot day weight and discovered I actually lost weight that week. You’ll find much more on the app.”
★★★★★
Great App!
“I’ve been taking Zepbound (and now compound tirzepatide) for a little over seven months and discovered this app last month. It’s been very helpful tracking the dosage, placement and timing of my shot each week. You can also add comments each day and it contains a great graphic showing your loss on each level of the drug. Highly recommend!!”
Tirzepatide basics: what to know while you track
Tirzepatide is a dual-action medication from Eli Lilly that activates both GIP and GLP-1 receptors, which slows digestion, reduces appetite, and improves insulin response. It is sold as Mounjaro, approved by the FDA in 2022 for type 2 diabetes, and as Zepbound, approved in 2023 for chronic weight management. Its half-life of about five days is what makes once-weekly dosing possible.
Clinical results for tirzepatide are substantial. In 72-week clinical trials for weight management, adults lost between roughly 16% and 22% of their body weight on average, depending on dose, and the medication also significantly improved blood sugar control in people with type 2 diabetes. The most common side effects are digestive: nausea, diarrhea, decreased appetite, vomiting, constipation, indigestion, and stomach pain.
Compounded tirzepatide is prescribed through compounding pharmacies, often at custom dose amounts. The FDA has raised concerns about unapproved GLP-1 products, so work with a licensed provider and a pharmacy you trust. Shotsy tracks compounded doses at whatever amount you are prescribed and keeps your history intact if you move between brand-name and compounded forms.
Tirzepatide forms at a glance
The right dose depends on which form of tirzepatide you take. Shotsy includes preset doses for Mounjaro and Zepbound and accepts custom amounts for compounded prescriptions, then charts your progress by dose either way.
| Form | Available doses | Schedule |
|---|---|---|
| Mounjaro (weekly injection) | 2.5 mg to 15 mg | Once weekly |
| Zepbound (weekly injection) | 2.5 mg to 15 mg | Once weekly |
| Compounded tirzepatide | Custom, set by your prescription | Usually once weekly |

Tirzepatide tracker: frequently asked questions
Is there an app to track tirzepatide shots?
Yes. Shotsy is a tirzepatide tracker app for iPhone and Android that logs your weekly shot, dose, and injection site for Mounjaro, Zepbound, or compounded tirzepatide, sends reminders before your next dose, and charts your weight, side effects, and estimated medication level over time.
Can Shotsy track compounded tirzepatide?
Yes. You can enter the exact custom dose amount your prescription calls for and change it whenever your prescriber adjusts it, without starting over. Shotsy tracks doses and schedules rather than vial inventory, so it works the same whether your tirzepatide comes in a pen or a vial.
Which tirzepatide medications does Shotsy support?
All of them: Mounjaro, Zepbound, and compounded tirzepatide with custom amounts. You can also run more than one medication at a time, which helps when you transition between forms.
Can an app tell me my exact tirzepatide level?
No. Shotsy estimates your medication level using published half-life data for tirzepatide, which is about five days. The chart is context for why appetite and side effects shift across the week, not a measurement, and it is never a substitute for your prescriber's guidance.
What happens if I switch between Mounjaro, Zepbound, or compounded tirzepatide?
A switch takes seconds. Mounjaro and Zepbound are the same molecule, and Shotsy supports multiple medications with separate schedules and custom dose amounts. It can display more than one on the estimated level chart at once, so your history carries straight through the transition.
Does Shotsy track tirzepatide side effects?
Yes. You can log nausea, constipation, fatigue, and other symptoms with severity ratings and notes. Side effects appear on the same timeline as your shots and dose changes, which makes patterns easy to spot and easy to discuss with your prescriber.
Does Shotsy help with injection site rotation?
Yes. You pick the injection sites you use, and Shotsy rotates them automatically, so you always know where the next shot goes even when you cannot remember where the last one went. It also charts progress by injection site, which helps prevent skin irritation from overusing one spot.
Can I share my tirzepatide history with my doctor?
Yes. Shotsy exports a PDF report of your doses, side effects, and weight trends, ready to bring to appointments or send to your care team.
