What's New in Vitamin K

7.0

December 11, 2019

A powerful new Search Facility has been added to the All Foods view. You can now search providing two search words/phrases. The first is required, but the second is optional. If a second word/phrase is provided, then you have the option of three possible ways to use the two words/phrases: 1) AND; 2) OR; and 3) BUT NOT. Search words/phrases are case insensitive. White space at the beginning and end of Search words/phrases will be removed. The "AND / OR / BUT NOT" operand selection is not taken into account unless there is a second Search word/phrase.

I have used this app for many years. I will always be on blood thinner so this app has helped me tremendously keeping at my INR goal consistently within my range. This means I am not needing to go to INR nurse but every 30 days. This app gives me freedom. Thank you! john

Trash. Do not buy.

Bought the app and tried to search a food. The search was unintuitive and the app didn’t have the food I wanted, which is a common food that a lot of people eat daily. I tried to look through the food list and the app crashed. Waste of $3. Seems like this app is a scam to prey on people who are trying to monitor their Vitamin K intake 🤬

Bad app

It is focused on bad eating habits like fastfood and canned food. It is not easy to fill in everyday on your phone. You have to scroll in stead you can search. Very old fashioned. Exaggerated detailed on vitam k. But it lacks an easy way of composing meals. I stick to my own made excell. It is not worth the money.

Great idea, still needs work

I was looking for something to help me track my Vitamin K intake since getting out of the hospital & now having to be on Coumadin for life due to a repeat of multiple blood clots. I am Heterozygous for FVL & was a vegetarian before all this. Dr’s & nutritionists have been helping to make the change since I can no longer be a full time vegetarian.
This app is a great idea, but I still missing things & I still haven’t figured out how to log my Vitamin K intake with it so I don’t go over 90mcg at the max intake. My Hematologist & Coumadin specialist both have told me to not have so much Vitamin K everyday & when I got to looking for a way to track my intake, came across this app & 1 other. This app had a rating review than the other.
If this app could be a easier to navigate for logging your intake, it would be more widely used and shared. I know of tons of other people on Coumadin who would love to be able to use something like this, but I won’t share the hassle until this is easier to use.

Needs some crucial work. Otherwise good.

This can be a crucial tool for folks new to the drug regime. K is obviously critical but instructions from hospitals are complicated and way too simplistic. This can be great for traveling or eating out to help with choices.
MUST STOP CONFUSION. Coumadin is just one of several brand names for the warfarin sodium generic. It may be the most advertised, so popular, but doctors and hospitals are not tied to that brand. AND the pill shapes, colors and codes are all different. Look up the code on the pill. But they’re all subject to Vitamin K issues.
PUT THE COLOR CODE ON THE APP AS A LEGEND. It’s not obvious and I don’t want to keep looking it up. Make it CLEAR.
WE ALL EAT A COLLECTION OF FAVORITE FOODS GENERALLY and then try other stuff now and then. Would be great if you could click a food that would then populate a Favorites category. More complex app development, yes, but would make usage much easier.
