## INR log Description
If you take Warfarin or Coumadin, INR log can help you to keep track of your treatment.  

It is easy to use and allows you to record all your INR results and your treatment prescribed by your doctor. Each day it will show you your warfarin dose and sends you an alert when your treatment is due. It will also remind you when to take your next INR test to help you achieve the best possible control.

It is very flexible and allows you to enter your own treatment range and select up to 3 different size tablets. You can record your dose as a daily dose or weekly dose and change the dose very easily based on your doctor's advice.

Your INR results are displayed graphically and in a table and you can add earlier INR results so you can see a complete record over time. 

You can keep track of how well your treatment is going by following your time within the therapeutic range. This is a good measure of anticoagulant control and ideally should be above 60%. You can also keep track of your drug adherence if you record your treatment every day. 

INR log is ideal for anybody taking warfarin, whether you are self-testing using a near patient testing device or if you are managed through an anticoagulant clinic or hospital laboratory.

INR log has been developed by a Consultant Haematologist with more than 25yrs of experience managing people on warfarin. It has been designed to be easy to use providing you with the important information you need to achieve safe control. 

Please note:

INR log does not provide any medical advice about warfarin treatment. INR log is designed to be used only in conjunction with support from your healthcare professionals. It is designed as a convenient means of recording your treatment. If you have questions regarding your treatment you should consult your doctor supervising your treatment.

## INR log Reviews in United Kingdom

### **--- "Lost all data- AGAIN, developer no show. 2025"
After years using and keeping it up to date. It crashes with no support from developer. To restart you have to delete the app and loose years of results!!!

Does anyone know of a better alternative. Ta
-- Balders3692, 2025-06-19

### ***** "Doesn’t work now"
Was a good app but doesn’t work after updating to iOS 15.4 Update. App seems to work again following update to iOS 15.5 but doesn’t have warfarin listed. Perhaps the next update will?
-- random kev, 2022-06-03

### ****- "Works again!"
Very pleased that this is working again following the recent iOS update. The only additional feature I’d like to see would be the ability to edit the dose for each day.
-- Caffiendish, 2022-05-31

### ***** "Great app"
This app works really well again now that IoS 15.5 has been released. (It had stopped working when IoS 15.4 hit. I wrote to the developer and got a really quick response that this had been unexpected and they were trying to obtain hardware for a fix). 
I know people have criticised that you can’t enter historical data if you forget to update the app when you take your meds - I just change the date / time on my iPad and hey presto, you can enter your meds for the day/time you took them.
I like the printable reports and regularly export them to notepad as a back up.
Easy to use and free, what more could you want?
-- SuWinter, 2022-05-26

### ****- "Not working with latest update"
Been using this for years

But today it just won’t open

My iPhone 13 pro max 1tb

Just auto updated and not inr app

Starts then crashes?

Is there support
For this
-- Acsnag, 2022-04-17

### *---- "App no longer works"
This app no longer works on my iPhone 12 since upgrading to 15.4.
-- TigerGirl69.UK, 2022-04-05

### ***** "Good app but stopped working?"
Hope it can be fixed.
-- rnzz99, 2022-03-24

### *---- "TOO MANY BUGS"
Useles app keeps crashing!!
-- CTGBita, 2022-03-17

### *---- "Not suitable for UK"
Doesn’t give option for warfarin so I can’t record my dosage of 8.5 mg. nothing comparable in the choices.
-- Drifflady, 2021-06-18

### *---- "Not flexible enough"
Too strict in its interpretation and can’t enter my medication pattern, which took a long time to work out! Also can’t add in confirmation later if you don’t have your phone with you at the time. Unusable as a result
-- Stumpypete, 2018-11-11

### *---- "Utterly rubbish"
Too restricted. Parameters do not allow dosage to be set as instructed by the anti-coagulant clinic. Bring back ‘MyINR’ app. Which was a more useful app
-- Philofnottm, 2018-07-17

### ***-- "Good, but 1 major flaw"
I like the simple layout and reporting, but didn't fully explore because I came across a major flaw that makes the app unusable for me. If you don't mark your dose off as taken on the day, then you can't add it later (I take mine just before bed, this can sometimes be after midnight, if so I only have the option of adding a double dose for the next day even though the following dose will be almost 24 hours later). This would mean I'm giving my GP erroneous data. Pointless for me, but probably still useable for many.
