Best App for Tracking GLP-1 Injections in 2025

GLP-1 injections are a once-a-week event, but the experience in between doses is where everything actually happens. Which site did you inject last time? Did you feel nauseous on day two or day four? Is your dose still at 0.5mg, or did you titrate up last month? How many doses are left in your pen?

Most people start by tracking this in the Notes app, a generic habit tracker, or a spreadsheet. And for the first week or two, that works fine. Then things get complicated. You forget which thigh you used last week. You cannot remember if the fatigue this week started before or after your injection. Your supply runs out and you are not sure when you last ordered a refill.

Generic tools were not built for this. GLP-1 therapy has a specific rhythm: weekly injections, rotating sites, evolving doses, and side effects that shift as your body adjusts. A good tracker needs to understand that rhythm.

What a good GLP-1 injection tracker actually needs

Not all injection tracking is created equal. Here is what actually matters for a GLP-1 user:

• Dose and titration history so you can see every dose you have taken, how the amount changed over time, and what to bring into conversations with your provider.
• Site rotation reminders because rotating between your abdomen, thighs, and upper arms is medically important and should be easy to follow systematically.
• Side effect logging for nausea, fatigue, constipation, headache, and other patterns that often line up with where you are in your injection cycle.
• Weekly schedule awareness because GLP-1 injections happen weekly, not daily, and your tracker should understand that rhythm.
• Weight correlation so your weight trend lives alongside your injection history rather than in a disconnected app.
• Supply tracking so you know how many doses remain and do not run out unexpectedly.

What most people use, and why it falls short

The three most common approaches are the Notes app, generic habit trackers, and spreadsheets. Each has a real weakness for GLP-1 users.

The Notes app is completely unstructured. You can write anything, which means you usually write nothing consistently. After a few months you have a long list of dates and doses but no easy way to query it, visualize it, or share it.

Generic habit trackers like Streaks or Habitica were built around daily habits. They do not understand a weekly injection, cannot log injection sites, and have no side effect vocabulary. They may celebrate injection day while missing everything that happens in between.

Spreadsheets are the most flexible of the three, but they require ongoing manual upkeep, offer no mobile experience worth speaking of, and cannot send reminders or visualize your titration timeline automatically.

What Steady tracks

Steady was designed from scratch for GLP-1 users. The injection log captures everything that matters in a single tap-through flow:

• Date and dose, including your current medication and exact dose amount.
• Injection site, with left and right abdomen, thigh, and arm options plus visible rotation history.
• Side effects from a curated GLP-1-focused list, plus room for notes.
• Supply tracker so you can log remaining doses and get alerted when you are running low.
• Titration timeline so you can see exactly when you titrated and how long you stayed at each dose.

Every injection log connects to the rest of your data, including weight, nutrition, and daily check-ins, so over time you build a much more complete picture of how your body is responding.
