Shotsy tracks your whole Zepbound routine in one place: weekly tirzepatide shots, dose changes, injection sites, side effects, weight, and estimated medication levels. Core features are free, on iPhone and Android.
Start Tracking Your Zepbound
Shotsy is a Zepbound tracker app that logs your weekly tirzepatide injection, guides injection site rotation, tracks side effects and weight, and estimates your medication level between shots. It supports every Zepbound dose from 2.5 mg to 15 mg, exports PDF reports for your doctor, and is rated 4.8 stars from 29,000+ App Store ratings. Core features are free on iPhone and Android.
Zepbound 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.
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.
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.
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.
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, and dose colors in the app match your Zepbound packaging.
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.
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.
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.
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.
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.
Verbatim five-star reviews from Shotsy's public App Store listing.
Great for Newbies to GLP-1s!
“I started using this when I started Zepbound to track my shots and weight loss journey. I use it every week so that I can vary my shot site and so that I can remember my overall trend. Even though I weigh myself every couple days, it’s important so see the graph over time to remember that this is a long term journey. Really great for beginners! My only criticism is that I wish it had something other than bananas for the loss comparison at the end! I also think it’d be great to add a “dose” translator from mls to units for people who transition from brand name to compound, and for syringes that measure in units instead of mls.”
Shotsy is so helpful!
“This is such an easy app to use. I found it a few months after starting Zepbound and went back and entered all my data. It was especially helpful during the month I took off to monitor the levels in my system. It has given me the data I need to plan my dosing schedule for when I get to maintenance and links to other apps to track my protein and weight automatically. I love it!”
LOVE!
“I truly love this app for tracking my Zepbound progress. I don’t often pay for app subscriptions, but this is one where I have no problem paying for premium to help support the developers and app improvements. The team takes suggestions and feedback seriously, keeps up with updates and bug fixes, and actually uses the app for their own personal tracking! Highly recommend.”
Fantastic app
“This is the first review I’ve ever left for an app. I started Zepbound in February, and I can’t tell you how helpful this has been for me to track my progress. It allows me to record where I place my weekly shots, the time of day I receive them, any side effects and my overall progress to goal, in both numbers and percentages. To say it is helpful as an understatement. Very user-friendly as well.”
Zepbound (tirzepatide) is a once-weekly injectable medication from Eli Lilly, approved by the FDA in 2023 for chronic weight management in adults with obesity, or overweight with a weight-related condition, and more recently for moderate-to-severe obstructive sleep apnea in adults with obesity. It activates both GIP and GLP-1 receptors, which slows digestion, reduces appetite, and improves insulin response. The same molecule is sold as Mounjaro for type 2 diabetes.
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. The most common side effects are digestive: nausea, diarrhea, decreased appetite, vomiting, constipation, indigestion, and stomach pain.
Zepbound 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. Maintenance doses are 5 mg, 10 mg, or 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 option | At least 4 weeks |
| 7.5 mg | Transitional step | At least 4 weeks |
| 10 mg | Maintenance option | At least 4 weeks |
| 12.5 mg | Transitional step | At least 4 weeks |
| 15 mg | Maximum dose | Ongoing |
