Store description excerpt
Rangewell is a logbook for people taking warfarin or another vitamin K antagonist. It records what you and your anticoagulation clinic decide. It never suggests a dose and never interprets a result. YOUR INR, AGAINST YOUR OWN RANGE Record a reading in seconds. Rangewell draws it against the target range your clinic gave you — the green band you can read at a glance — so you can see the shape of your control instead of a column of numbers. THE WEEK, NOT A DAILY DOSE Warfarin is prescribed as a week: one tablet Monday, Wednesday and Friday, half the other days. Generic pill reminders cannot hold that. Rangewell can. Set each day separately, in quarters of a tablet or in milligrams, and see the weekly total your clinic speaks in. TWO REMINDERS THAT MATTER One for the dose, on the days your schedule actually has one. One for the next INR test — the appointment people say they forget most, because a missed tablet is obvious and a missed test is not. BUILT TO BE READ Large type, high contrast, full VoiceOver support, and nothing that depends on telling green from amber. Text scales to the largest accessibility sizes without losing a word. RANGEWELL PRO • Time in Therapeutic Range — the Rosendaal figure your clinic tracks, over 30, 90 or 365 days • A printable clinic report: readings, doses, TTR and events on one page • An interference journal for vitamin K, antibiotics, alcohol and illness • Bleeding and bruising records • Encrypted iCloud sync across your devices • Travel mode and an emergency card EVERYTHING EXPORTS Readings, doses and everything logged alongside them go into one CSV file — not four, so it opens in any spreadsheet and travels by email or AirDrop. A logbook you cannot get your data out of is not a logbook. YOUR DATA IS YOURS Everything stays on your device unless you turn on iCloud sync, and then it goes only to your own iCloud account. No advertising, no tracking, no accounts. Rangewell is not a medical device. It does not provide medical advice. Always follow your anticoagulation clinic.
