iPhone
GLP-1 tracker for Ozempic, Wegovy, Mounjaro, Zepbound & more. Log every dose, take a 3D body scan and measure muscle loss, not just weight. Free to use.
Tiro is the GLP-1 companion that turns your shot routine into a habit you can actually see — and keeps your body private.
Log a dose in seconds and watch a beautiful estimated medication-level curve respond in real time. Stay ahead of every injection with a clear next-shot countdown, an adaptive schedule that handles late doses gracefully, and a titration plan that tells you exactly when your dose steps up. Tiro brings clinical-style tracking and a genuinely delightful daily experience into one app built for people on GLP-1 medications.
— WHAT TIRO DOES —
LOG SHOTS THE EASY WAY
Record medication, dose (mg), date, time, injection site, and how it felt. A satisfying "you did it" moment confirms every shot. Full history, editable any time.
SEE YOUR ESTIMATED MEDICATION LEVEL
A signature level curve estimates how much medication is in your system over time — solid for the past, projected ahead — across week, month, 90-day, and all-time ranges. A clear "how we estimate this" explainer shows the pharmacokinetic approach behind it.
NEVER MISS A DOSE
Next-shot countdown, dose reminders, and an adaptive late-dose policy that nudges your schedule back toward your target time instead of breaking it. A Live Activity and home-screen widget keep your next shot one glance away.
KNOW WHEN YOUR DOSE STEPS UP
Build a titration schedule and see your upcoming dose changes mapped out on a calendar, so a dose increase never sneaks up on you.
ROTATE YOUR INJECTION SITES
A body-map heatmap shows where you've injected so you can rotate sites and give each spot a rest.
TRACK SYMPTOMS THAT MATTER
Log nausea, fatigue, "food noise," cravings, and more with a quick severity scale, and watch how they trend alongside your doses.
PROTEIN-FIRST FOOD LOGGING
Snap a photo of your plate, speak it, or type it, and Tiro estimates calories and macros — with protein and fiber up front, the way GLP-1 users care about. Scan packaged-food barcodes too. Recognition runs on our secure server; your photos are processed for the estimate and not stored afterward.
A PRIVATE, ON-DEVICE BODY SCAN
A short guided camera capture estimates body measurements using on-device machine learning. Your body-scan photos NEVER leave your phone — they're analyzed on-device and only the resulting numbers are saved. Keep progress photos and watch your shape change over time.
WEIGHT, WATER & STREAKS
Log weight and water, keep a daily streak alive, and unlock milestones that make consistency feel good.
MAKE IT YOURS
Themes, accent colors, alternate app icons, light/dark mode, and haptics.
— PRIVACY IS THE PRODUCT —
• Body-scan photos NEVER leave your device — analyzed on-phone, only measurements are kept.
• No ads. No data selling. No third-party analytics SDKs. No tracking of you across other apps or websites.
• No account required to start — Tiro is anonymous-first. Sign in with Apple, Google, or email later only if you want backup or cross-device restore.
• Food photos, voice notes, and typed entries are sent securely to our service for recognition and are not stored after they're processed.
• Export or delete all your data anytime, right in the app.
— IMPORTANT —

Medication-level estimates and body measurements are approximate and for general awareness only.

Reminders that actually arrive
Earlier versions could be granted notification permission silently by iOS, so dose reminders never made a sound or reached your lock screen. Tiro now asks you properly - and has its own notification sound.
A rebuilt Shots page
Your injection sites on a body map you can actually read, with the belly split into four separate regions so rotation means something. Every shot you have logged shows as its own dot, so a zone tells you at a glance how much it has been used. Logging a shot takes fewer taps.
Your journey, week by week
What to expect at the stage you are actually at, plus a clearer view of how your symptoms have moved over time.
Share with your clinic - only if you want to
If your clinic uses Tiro, a six-character code links your account to them. You choose exactly what they can see, every time they open your data is recorded for you to read, and you can disconnect at any moment. Tiro works exactly the same if you never use this.
Gentle nudges
Quiet reminders when it has been a while. They are worked out on your phone - nothing is sent anywhere to produce them - and you can switch them off in Preferences.
Charts that explain themselves
An empty chart now shows a labelled preview of what will appear once you log, instead of a blank space.
