Ratings and Reviews

Anju - fantastic App just for the job


Two weeks ago I was diagnosed with an arterial clot in my lower leg and now I will be on anticoagulant therapy (warfarin) for life. I was given a yellow book but with the eWorld and smart phones I searched for an ideal App. Having done a good 'search', the OATbook tops the bill.
As many other comments excellent App for monitoring and managing INR.
As far as support is concerned, ROB thank you so much for your very quick response. Some suggestions:

On the calendar next to dosage there is a 'grey tick' only on the past dates which I think is to indicate the dosage has already been taken or 'red tick' if you have forgotten or cancelled a dose - is that so? If so you could display that icon with an explanation for on the App info.

For entering notes - brilliant facility on the day but I would benefit from seeing the current date on the 'notepad'

I love the email facility with the 3 different options as I can email the information - chart and table to my medics. However, for me the notes facility is MOST important as my body is extremely sensitive even to things like half an avocado in a salad and rather than having to retype the information which I am noting on my OATbook notes could be sent along with the email.

I know I am asking too much but you did say that you wanted suggestions........

With kind regards, a fellow 'rat poison' Victim.


Useful app! Not quite perfect tho...


EDIT: I've recently changed clinic and to venous tests which means if in range, I don't get my results for five days or so. This means with no result for my last test entered and no date for my next one, I'm left completely without reminders for up to a week after every test. The only safe way around this, I've found, is to not use appointments at all and enter a dummy one way off in the future. It seems a bit mad that the app defaults to no reminder if there's no appointment set! It's still quite awkward for adding one off/booster doses but when it works, it's great.

Old 4* review:

I agree with some other comments, not the most intuitive at first but the basic functionality is there and the support is prompt.

I've now been using this for a month and haven't missed a dose all year, so that's the main reason I bought it ticked off.

It need a proper way to record one-off or booster doses, I often have to take, say, 10mg two days after a low test and then back to my normal 7mg, there's currently no way to do this.

Better graph formatting (ideally zoomable) would be good, currently it looks like my INR has been going haywire when really the fluctuations are quite small.

iPhone 5 graphics would be nice.

iCal integration would be pretty awesome too since I use that to record other heart related stuff on the move.

All-in very useful, but missing that fifth star on the points mentioned above.

Good, but 3 major issues!

Nice simple app. Several plus points. It's easy to add and amend historic data. I like the graph with list of dates and results below it (although you can't access the notes in this view). The only issues I have are:
1, it's over priced (it isn't worth it with the following, although an update to correct them would make it value for money).
2, it does not export the notes.
3, no option to export the record of doses taken on days that there is no test result (in particular misses doses). I self manage, so I want my GP to see my notes with doses taken/missed and any temporary/ long term increase/decrease and on which days without having to manually add this information again (to the email). However, I can see that exporting this info can make for very big emails, so only needs to be an option for when there are missed days. However, if you could export the notes then you could make a note of missed doses that relate to a test result.
4, no access to notes in graph view.
5, when you mark a dose as taken you get a vibrating acknowledgement alarm. You can't turn it off and my partner hates to hear it when I update it (OK, I normally do that at bedtime lol), minor detail, but it is annoying and an option to silent this would be good.
