Why Mounjaro users track

A weekly shot is easy to lose track of

Mounjaro 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.

Titration takes months

Most people step through several doses, from 2.5 mg up to as high as 15 mg, spending at least four weeks at each level. Tracking how you respond at every step gives you and your prescriber real data for the next dose decision.

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 can return before your next dose. Seeing your estimated level explains those shifts and helps you plan around them.

How Shotsy tracks your Mounjaro journey

One-tap shot logging with smart reminders

Log each weekly injection in seconds, including dose, time, and injection site. Reminders and home-screen countdown widgets keep your next shot front and center.

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 step, so you can see how your body responded at 5 mg versus 7.5 mg. 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 Mounjaro users say about Shotsy

Verbatim five-star reviews from Shotsy's public App Store listing.

★★★★★

Great app

“When I started taking Mounjaro my daughter recommended this app. It tracks not only the day that you take your shot but also the site in which you place it. Your side effects. Your weight. It's very handy for those taking GLP1 injections. It will send you reminders so that you do not forget it's time for the next shot. Highly highly recommend this app. I now recommend it to my patients taking insulin or GLP's. Easy to use!”

★★★★★

Mounjaro

“I wished I would have started this two years ago. This is like a miracle drug from the Lord. Mounjaro is a tool to help me get this unwanted menopausal weight off of me. I love this Shotsy app because it helps me to keep track of my shots the date I take my shots, the position in which you injected your shot. Shotsy even allow me to leave notes for how I felt that week after taking the shot. I highly, highly recommend this Shotsy app.”

★★★★★

Organized

“I started Mounjaro a month ago & used the free portion of the app for a week. I then upgraded to a free week of the pro version. After the week was up I purchased the annual plan. It syncs with my other apps (water tracker, calorie tracker, and weight tracker) and keeps all my data in one place. I love being able to see what my levels are and know what to expect from each shot & my symptoms. It's a great tool to have in my pocket!”

★★★★★

Lifesaver App

“This app helps me keep up with my biologic as well as Mounjaro for type 2 diabetes. Having to take multiple injections and keeping up with the location of each shot is daunting. However this app lets me keep track.”

Mounjaro basics: what to know while you track

Mounjaro (tirzepatide) is a once-weekly injectable medication from Eli Lilly, approved by the FDA in May 2022 to improve blood sugar control in adults with type 2 diabetes. It activates both GIP and GLP-1 receptors, which slows digestion, reduces appetite, and improves insulin response. The same molecule is sold as Zepbound for chronic weight management.

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.

Mounjaro dose schedule

Mounjaro starts low and steps up gradually. Per the FDA prescribing information, treatment begins at 2.5 mg once weekly for four weeks, then increases to 5 mg, with further increases of 2.5 mg allowed after at least four weeks at the current dose, up to a maximum of 15 mg. Shotsy tracks your dose at every step and charts your progress by dosage.

Dose	Phase	Typical duration
2.5 mg	Starting dose	Weeks 1 to 4
5 mg	First maintenance step	At least 4 weeks
7.5 mg	Step up if needed	At least 4 weeks
10 mg	Step up if needed	At least 4 weeks
12.5 mg	Step up if needed	At least 4 weeks
15 mg	Maximum dose	Ongoing

Mounjaro tracker: frequently asked questions

Is there an app to track Mounjaro shots?

Yes. Shotsy is a Mounjaro tracker app for iPhone and Android that logs your weekly tirzepatide shot, dose, and injection site, sends reminders before your next dose, and charts your weight, side effects, and estimated medication level over time.

Is Shotsy free for Mounjaro tracking?

Yes. Shot logging, reminders, injection site rotation, side effect logging, and weight tracking are all free. An optional upgrade adds advanced analytics.

Can Shotsy remind me when my Mounjaro shot is due?

Yes. Shotsy sends notifications on your schedule and offers home-screen countdown widgets, so you always know how many days remain until your next Mounjaro injection.

Does Shotsy track Mounjaro 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.

What happens if I switch from Mounjaro to Zepbound or another GLP-1?

Shotsy supports multiple medications with separate schedules, so a switch takes seconds. Zepbound is the same molecule as Mounjaro (tirzepatide), and Shotsy can display more than one medication on the estimated level chart at once during a transition.

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.

Does Shotsy help with Mounjaro 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 Mounjaro 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.
