INR Notebook: Warfarin Record

INR Notebook is a private record book for people taking warfarin. Keep your INR results, the dose instructions your clinic gives you, the doses you take, your clinic visits, your health diary and what you eat together, and see them clearly.

It is a notebook, not a clinician. INR Notebook never calculates or changes a warfarin dose, and it never tells you what to do about a result. It shows you what you and your clinic have recorded.

WHAT YOU CAN KEEP
• INR results, with the target range your clinic gave you and a chart of every reading against it
• Dose instructions exactly as your clinic wrote them, including alternating doses such as 5/2.5, and holds. Set them out day by day to see each day's dose at a glance
• The doses you take each day, kept separate from what was prescribed, with a home-screen widget to record today's dose in one tap
• Clinic visits, with your next appointment and INR test on the home screen and in your phone's calendar
• Contacts for your clinic, pharmacy or cardiologist, a tap away to call or email
• Reminders for your daily dose, INR tests and clinic appointments, and one before your tablets run out
• A health diary for symptoms, events such as illness, travel or dental work, other medicines, your weight, blood pressure and pulse
• A summary since your last clinic visit, and questions to ask at the next
• How many readings were in range, and the doses taken this month
• A change history on every INR result, so nothing is silently overwritten

FOOD AND SAFETY
• A food log: photograph a meal or type it in, even for an earlier day, and see its estimated vitamin K and nutrients day by day. Photo reading needs a service you set up with your own key, and every estimate is labelled as one.
• Foods on the vitamin K list included in the app are graded from the list itself, word for word
• Water today, against a daily amount your clinic gave you
• A vitamin K food guide and meal planner based on the diet document included in the app
• The bleeding danger signs from the warfarin card, one tap from the home screen
• An emergency card for anyone helping you, which can show on your phone's lock screen if you choose

YOUR RECORDS STAY YOURS
• Everything is stored on your phone. There is no account. Your records leave it only inside an encrypted backup you set up yourself, or as a meal or medicine photo you choose to have read.
• An optional app lock with a PIN or your fingerprint
• Encrypted backups on your phone, and an optional weekly encrypted copy to a Google Drive folder you choose
• A 64-digit recovery code, so a backup can be restored on a new phone
• PDF, CSV and JSON exports to share with your clinic, of everything or recent months

FREE FOR THREE MONTHS, THEN PREMIUM

IMPORTANT
INR Notebook is not a medical device and does not diagnose, treat, cure or prevent any medical condition, or give medical advice.
