Lose the fat.
Keep the muscle.

Tiro tracks the four things your shot doesn't — protein, dose, symptoms, and body composition — so the weight you lose is fat, not muscle.

  • Scan a meal and get your protein in seconds
  • Log every shot and watch your levels
  • Track your body, not just the scale

Tiro is a tracking companion, not medical advice. Always follow the dosing plan from your prescriber.

Everything your shot
doesn't track

Your GLP-1 handles appetite. Tiro handles the four things that decide whether the weight you lose is fat or muscle.

Protein is the plan.
Not calories.

On a GLP-1, your appetite does the calorie math for you. The risk is muscle. Tiro turns your target into a floor you clear — split into meals you can actually finish.

  • A personal floor from your weight and goal
  • 20–40g per-meal targets, tracked live
  • A running bar, not a guilt tracker
Calculate your floor

In the trials, people lost 15–21% of their body weight. How much of that was muscle is up to you.

Average total body-weight loss was ~15% on semaglutide 2.4 mg (STEP 1) and ~21% on tirzepatide 15 mg (SURMOUNT-1), alongside a reduced-calorie diet. Individual results vary. Tiro is a tracking companion, not medical advice.

check-in with proof

Log doses and symptoms in two taps. Show up to your next appointment with a clear picture of what's working — not a foggy memory of a rough month.

  • Dose schedule and reminders
  • Symptom patterns aligned to your dose days
  • A shareable report your prescriber can read

Built for the part
nobody warns you about

The protein floor changed everything. I stopped guessing and started hitting an actual number every day.
