Shotsy is a GLP-1 side effects tracker for iPhone and Android. It logs symptoms such as nausea, constipation, and fatigue with severity ratings and notes, places them on the same timeline as your shots and dose changes, and charts them against your estimated medication level, so you can see what actually follows a dose increase. A PDF export turns the record into something you can hand your doctor. Core tracking is free, rated 4.8 stars from 29,000+ App Store ratings.
Why GLP-1 side effects need context
A symptom alone tells you very little
Tuesday's nausea means one thing on its own and something much more useful next to Monday's dose increase. Side effects only become information when they sit on the same timeline as your shots, doses, and meals.
Side effects cluster around dose changes
The most common GLP-1 side effects are digestive, and they are most likely to appear when a dose goes up. Logging symptoms through each titration step shows you and your prescriber exactly how each level treated you.
Appointments need specifics, not memories
Telling your doctor you had some nausea, sometimes, is hard to act on. A dated log with severity ratings turns the same experience into a record your prescriber can actually use to adjust your plan.
Patterns emerge over weeks, not days
Many people feel different on day two of their shot cycle than on day six. You will not spot that from memory, but a few weeks of consistent logging makes the weekly rhythm obvious.
How Shotsy tracks your side effects
Symptoms on the same timeline as your shots
Every side effect lands next to your dose history, so a rough stretch lines up visibly with the dose change or the shot that preceded it. That single view is what turns a diary into answers.
Context from estimated medication levels
Shotsy charts your estimated medication level between doses using published half-life data. Seeing symptoms rise and fall with that curve helps explain why some days are harder, though the chart is an estimate for context, never a measurement.
A calendar view of your week
A side effects calendar shows your symptoms at a glance, day by day, so streaks and gaps stand out. Scanning a month takes seconds when it is laid out visually.
Compare by injection site and dose
Because Shotsy also tracks where you injected and at what dose, you can compare how you felt across sites and dose levels, useful detail when you and your prescriber are weighing the next step.
Doctor-ready PDF reports
Export your side effect history alongside your doses and weight trends as a PDF, ready to bring to appointments or send to your care team.

GLP-1 side effects: what to know while you track
The most common side effects of GLP-1 medications are digestive. In the pooled placebo-controlled trials reported in the FDA prescribing information, nausea affected 44% of adults taking Wegovy (semaglutide 2.4 mg) versus 16% on placebo, with diarrhea at 30%, vomiting at 24%, and constipation at 24%. For Zepbound (tirzepatide), nausea affected 25% to 29% of adults depending on dose, versus 8% on placebo.
Timing matters as much as frequency. The Zepbound prescribing information notes that the majority of nausea, vomiting, and diarrhea events occurred during dose escalation and decreased over time, and the Wegovy label reports the same reactions most frequently during dosage escalation. That is exactly when a dated log earns its keep. Tracking also matters for safety conversations: if your log shows persistent vomiting, severe abdominal pain, or signs of dehydration, that is a record to bring to your care team promptly rather than a pattern to wait out. Shotsy organizes what you experienced; deciding what it means always belongs to your doctor.
What to log when a side effect happens
A useful side effect entry captures more than the symptom itself. Here is what to record, and how Shotsy handles each piece.
| What to log | Why it matters | In Shotsy |
|---|---|---|
| The symptom and its severity | A mildly queasy morning and a rough night need different conversations | Built-in and custom symptoms with severity ratings |
| Date and time | Shows how symptoms line up with your dose cycle | Logged automatically with every entry |
| Days since your last shot | Many symptoms peak in the first days after an injection | Visible on your shot timeline and level chart |
| Your current dose | Dose increases are the most common trigger | Every entry sits alongside your dose history |
| Food and water that day | Meals and hydration often make the difference | Calorie, protein, and water logs share the timeline |
| What helped | Notes turn one bad day into a plan for the next one | Free-form notes on any entry |
Shotsy tracks and organizes; it never diagnoses. Severe or persistent symptoms belong with your care team, not an app.
GLP-1 side effects tracker: frequently asked questions
What is the best app to track GLP-1 side effects?
Shotsy is built for exactly this: it logs symptoms with severity and notes, keeps them on the same timeline as your shots and dose changes, charts them against your estimated medication level, and exports the record as a PDF for your doctor. It is rated 4.8 stars from 29,000+ App Store ratings, and side effect logging is free.
Which side effects should I track?
Start with the digestive symptoms that are most common on GLP-1 medications: nausea, vomiting, diarrhea, constipation, and abdominal discomfort. Add fatigue, headache, appetite changes, and injection site reactions if you notice them, plus anything unusual for you. In Shotsy you can also create custom symptoms.
Do GLP-1 side effects get better over time?
Per the FDA prescribing information, digestive side effects are most commonly reported during dose escalation. Many people find that a symptom which flared after a dose increase settles as their body adjusts, but everyone responds differently, which is why a dated log is so useful. If a side effect persists or worsens, talk to your prescriber.
Can Shotsy tell me whether a side effect is dangerous?
No. Shotsy is for tracking and education only; it does not diagnose symptoms or tell you whether one is serious. Symptoms such as severe abdominal pain, persistent vomiting, or signs of dehydration or an allergic reaction warrant contacting your care team promptly.
Can I share my side effect history with my doctor?
Yes. Shotsy exports a PDF report of your side effects alongside your doses and weight trends, ready to bring to appointments or send to your care team.
Does Shotsy track side effects for my specific medication?
Yes. Shotsy works with every major GLP-1 medication, including Ozempic, Wegovy, Zepbound, Mounjaro, oral semaglutide, and compounded semaglutide or tirzepatide, and your side effect log stays intact if you switch.
Is side effect tracking free in Shotsy?
Yes. Side effect logging with severity and notes is part of Shotsy's free core features, along with shot logging, reminders, injection site rotation, and weight tracking.
Why do my side effects change through the week?
Medication levels rise after each dose and fade before the next one, and symptoms often follow that curve. Shotsy's estimated medication level chart makes the rhythm visible, which helps explain why day two can feel different from day six. The chart is an estimate for context, not a measurement.
