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
