A GLP-1 shot tracker should record four things per injection: the date, the medication, the dose and the site. GLP-1 Companion logs those in a few taps, shows when each of six injection sites was last used, reminds you on shot day, and keeps daily protein, water, appetite and symptom notes beside the shot history. It works for Ozempic, Wegovy, Mounjaro, Zepbound and other GLP-1 medicines, with no account.
What to log for each shot
Paper charts and notes apps both work until the week you cannot remember whether you injected on Tuesday or Wednesday. A dedicated tracker earns its place by making the entry quick enough that you always do it. Four fields are enough:
- Date. Weekly medicines depend on a steady interval, so the date is the entry that matters most.
- Medication. GLP-1 Companion lists Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda, Victoza, Rybelsus, a compounded option and "Other".
- Dose. Doses often change in steps over the first months. The dose picker offers the usual strengths for the medicine you chose, such as 0.25, 0.5, 1 and 2 mg for Ozempic.
- Site. One of six: stomach, thigh or arm, each left or right.
Everything else is optional context. Log it when it helps and skip it when it does not.
The week between shots
The shot takes a minute. The other six days are where most of the questions come from: appetite that disappears, a rough stomach on day two, energy that dips midweek. The app keeps three small daily entries on the Today screen.
- Protein in grams against a goal you set, with quick-add buttons.
- Water in milliliters, again with quick-add buttons.
- Food noise, a slider from quiet to constant, for how intrusive food thoughts are.
The Journal lists each day as one row with those numbers and any symptoms you tagged, so a month reads as a table rather than a diary. If food is the hard part, the protein tracking guide and the low-appetite meal planner go further.
Reminders and widgets
Choose a shot day once and the app sends a notification that day. The Today screen confirms when the week's shot is logged ("Shot done for this week. See you next Wednesday."). Home Screen and Lock Screen widgets show the next dose without opening the app. The reminders guide covers the setup in detail.
Injection-site rotation
Patient leaflets for the weekly GLP-1 pens describe rotating the injection site. The Shots screen turns your history into a grid of six sites, each labeled with how recently it was used. You see at a glance that the left thigh was last week and the right arm was a month ago. The site rotation guide explains the grid and offers a printable alternative.
Privacy: no account, stored on your phone
Health notes are personal, and many trackers ask for an email address before you can log anything. GLP-1 Companion has no sign-up. Entries are stored locally on your iPhone. Apple Health is optional and limited: the app can read and save weight, and Pro can write protein, water and fiber. More detail is in the no-account guide.

Guides for specific medicines
The routine is the same for every weekly pen, but doses and pen types differ. There is a page for each: Ozempic, Wegovy, Mounjaro and Zepbound.
Common questions
Do I need a special app, or will Notes do?
Notes works if you are consistent. A tracker helps with the parts Notes cannot do: reminding you on shot day, showing which site is next in your rotation, and lining up symptoms against shot dates.
Does it work for daily GLP-1 medicines?
The medication list includes Saxenda, Victoza and Rybelsus. The Today screen and reminders are built around a weekly shot day, so the app fits weekly injections best.
Will it interpret my symptoms?
No. The app records what you enter and shows it back to you. It does not diagnose, score or recommend treatment. Bring anything that worries you to your prescriber.
Is Pro a subscription?
No. The App Store listing describes Pro as a single one-time purchase. Check the listing for the current price.
Does it sync between devices?
Records are stored on the iPhone you log them on. Pro can export a CSV file if you want a copy elsewhere.
