GLP-1 Shot Tracker: OneShot

On Zepbound, Mounjaro, Wegovy or Ozempic? OneShot keeps every shot under control: countdown to your next dose, titration steps, injection site rotation, side effects and your weight curve, all on one clean screen.

[Why OneShot]
One shot a week, a new dose step every four weeks, side effects that change from week to week: forgetting a dose, doubling up or losing track of which step you're on happens faster than you think. OneShot is built only for this journey. You stop relying on memory and finally see, in numbers, how your body responds to treatment.

[Supported medications]
- Tirzepatide: Mounjaro, Zepbound (pens and vials)
- Semaglutide: Wegovy, Ozempic
- Custom medication: add any drug with its own dose and schedule, including compounded semaglutide or tirzepatide, the Wegovy pill, Foundayo, or daily pens like Saxenda
- Official dose steps preloaded for every medication, switch drug or step at any time

[Features]

Shot log and reminders
Record the date, dose, injection site and medication. OneShot calculates your next shot and reminds you the day before, on shot day and in the evening if you haven't logged yet. Your home screen shows how much effect is left from your last dose.

Injection site rotation
Twelve body zones (abdomen, thighs, arms, hips) so you rotate correctly and avoid skin reactions.

Titration steps
Enter your starting dose and the schedule your doctor set. OneShot tells you when it's time to move up to the next step.

Weight and BMI
One weigh-in a day, logged in a second. Trend curve, automatic BMI, goal weight and pounds or kilos to go.

Side effects
Nausea, constipation, fatigue, headache, hair loss, appetite loss: log the symptom, its severity and intensity. Every side effect is linked to the shot it followed, so you can tell your doctor exactly what happened and when.

Calories and macros without typing
Snap a photo of your plate, scan a barcode or just say what you ate: OneShot calculates calories, protein, carbs and fat. Nutrition goals are calculated for you and adjustable anytime, with protein front and center.

Water and steps
Daily water goal, steps synced with Apple Health and walks with live tracking.

Progress photos
Before photo, after photo, side-by-side comparison with your weight change. Your photos stay private.

Weekly AI insights
Every week OneShot combines your shots, weight, side effects and food into a report written for GLP-1 users: what happened, which dose step gave the best results, when side effects peak, and what to adjust next. No generic advice, only your data.

Streak and motivation
A streak of consecutive logging days keeps you consistent, with an evening reminder before it breaks.

[Important]
OneShot is a logging and reminder tool. It does not replace medical advice and does not sell medication. GLP-1 medications are prescription drugs: always follow your doctor's instructions, especially for any dose change.
