Coagly Turns Warfarin Management Into a Daily Checklist
A free warfarin and INR tracker for iPhone and Android, with dose reminders, blood-test planning, trend tracking, and time-in-range calculations.
Field notes
The workflow begins with a prescriber-provided target range and a weekday dosing schedule, then turns logged INR results, doses, and appointments into reminders, adherence history, and a time-in-range measure. The site says TTR uses Rosendaal linear interpolation, while its test planner can produce a calendar file and its records can be exported or imported as CSV. Browser calculations are described as local, with nothing uploaded, and the checker warns against changing medication doses from its output.
