Titra

The app lets users record each GLP‑1 medication administration—supporting brands such as Ozempic, Wegovy, Mounjaro, and Zepbound—by entering dose amount, time, and injection site. It visualizes an estimated serum concentration using pharmacokinetic modeling, shows half‑life decay, and provides a body map that warns against repeated use of nearby injection zones. Users can also log side effects, rate daily food‑related cravings, and track nutrition and total daily energy expenditure.

In addition to personal tracking, the software compares an individual’s weight‑loss trajectory with published clinical trial outcomes (e.g., STEP‑1, SURMOUNT‑1) and with anonymized community data, offering percentile rankings and cohort curves while preserving privacy through differential‑privacy techniques. Generated reports can be exported for discussion with healthcare providers.

The platform is free, available on iOS and Android in 24 languages, stores data locally on the device, and complies with GDPR. It includes optional biometric locks, has no advertisements, and is positioned as an experimental tool built from patient input and clinical pharmacokinetic literature.
