Features
Designed around your
GLP-1 medication journey
Every feature in Titra was built with input from real GLP-1 patients and informed by published clinical pharmacokinetic data.
Serum Level Estimator
See your estimated blood concentration using pharmacokinetic modeling. Titra calculates half-life decay from your last dose to show where your medication level likely is right now.
Injection Site Rotation
Visual body map with 14 injection zones. Smart warnings prevent you from injecting too close to your navel or reusing the same site too soon, helping prevent lipodystrophy.
Weight & Progress Tracking
Chart your weight alongside medication data. See correlations between dose changes and weight trends to understand how your GLP-1 medication is working.
Side Effects with Clinical Context
Log symptoms and see how common they are based on clinical trial data. Get self-care tips sourced from official prescribing information for medications like Ozempic and Mounjaro.
Food Noise Tracker
Rate your food noise (appetite cravings) on a 0–10 scale daily. Track how GLP-1 medications reduce intrusive food thoughts over time with clear trend charts.
Health Data Sync
Connect Apple Health or Google Health Connect to pull in steps, calories burned, nutrition data, heart rate, and sleep — all alongside your GLP-1 tracking in one app.
Doctor Reports
Generate professional PDF summaries to share with your healthcare provider. Includes your dose timeline, weight trajectory, side effect patterns, and medication adherence data.
The Science
Understand what's happening inside your body
Titra's Serum Level Estimator uses published pharmacokinetic data — including half-lives, bioavailability, and absorption rates — to model your estimated medication concentration over time. For example, semaglutide (Ozempic, Wegovy) has a half-life of approximately 7 days, while tirzepatide (Mounjaro, Zepbound) has a half-life of about 5 days.
Based on the same pharmacokinetic data your doctor references, presented visually so you can understand your medication levels between doses.

Frequently Asked Questions
Common questions about Titra
What is Titra?
Titra is a free mobile app for iOS and Android designed specifically for people taking GLP-1 receptor agonist medications like Ozempic, Wegovy, Mounjaro, Zepbound, and Rybelsus. It helps you track doses, visualize your estimated serum levels using pharmacokinetic modeling, rotate injection sites safely, log side effects with clinical context, monitor weight changes, track food noise reduction, and generate PDF reports to share with your doctor.
How does Titra's serum level estimator work?
Titra's Serum Level Estimator uses published pharmacokinetic data to model your estimated medication blood concentration over time. It factors in each medication's specific half-life (for example, semaglutide has a half-life of approximately 7 days, while tirzepatide's is about 5 days), bioavailability, and absorption rates. After you log a dose, the estimator calculates the decay curve to show your estimated level at any point. This is for informational purposes only — always consult your healthcare provider about your medication levels.
Which GLP-1 medications does Titra support?
Titra supports all major GLP-1 receptor agonist medications including: Ozempic (semaglutide injection for type 2 diabetes), Wegovy (semaglutide injection for weight management), Mounjaro (tirzepatide for type 2 diabetes), Zepbound (tirzepatide for weight management), Rybelsus (oral semaglutide), Wegovy Pill (oral semaglutide for weight management), generic semaglutide, and orforglipron. Each medication has its own pharmacokinetic profile for accurate serum level estimation.
Is Titra free?
Yes. Titra is free to download and the core features — dose tracking, injection site rotation, weight logging, side effect tracking, and food noise monitoring — are all free. An optional titra+ premium subscription is available for advanced features like the Serum Level Estimator, enhanced reports, and health data sync with Apple Health and Google Health Connect.
Is my health data private?
Yes. Titra is designed to be private by default. All health data is stored locally on your device and is never sold or shared with third parties. Titra contains no ads and is GDPR compliant. You can delete all of your data at any time from within the app settings. If you choose to enable optional cloud backup, your data is encrypted.
What is food noise and why does Titra track it?
Food noise refers to persistent, intrusive thoughts about food and eating that many people experience. One of the most commonly reported benefits of GLP-1 medications like Ozempic and Mounjaro is a significant reduction in food noise. Titra lets you rate your food noise daily on a 0–10 scale and charts the trend over time, giving you a clear picture of how your medication is affecting your appetite and food-related thoughts.
Why is injection site rotation important?
Rotating injection sites prevents lipodystrophy — changes in the fat tissue under the skin that can affect how well your body absorbs medication. Injecting in the same spot repeatedly can lead to lumps, scarring, or reduced medication effectiveness. Titra's injection site rotation feature provides a visual body map with 14 zones, tracks where you last injected, and warns you if you're about to use a site too soon or too close to your navel (which should be avoided for subcutaneous injections).
