INR Tracker – Dose & Log

This app is an INR diary and analysis tool for anticoagulation therapy (e.g., warfarin/phenprocoumon).

Your dashboard gives a quick overview: trend, stability and TTR (Time in Therapeutic Range) help you interpret results at a glance. Under Analysis → Statistics you get a detailed breakdown for week or month to compare time periods.

In More statistics, you’ll find additional detailed analyses: • Extended Rosendaal TTR with breakdown: below / in / above range • Optional gap-cap (limits interpolation for long gaps between measurements) • Box plot for distribution (median, spread, outliers) • Variability/stability metrics: SD, CV and IQR • Patterns: streaks & recovery • A compact monthly overview • PDF export with log
