Medication Management Made Fun & Easy

I take certain medications that can only be refilled every 28 days. You probably know the ones I’m talking about, am I right? Anyway, I always used to calculate the refill dates in my head, it’s not difficult, and honestly it’s probably better for my cognitive function to do it that way. But I’ve calculated it wrong a time or two - mildly embarrassing to have to be told I came back too soon for my refill. Never happens any more with this Date and Time app. I can spin out 28 days later (coincidentally the title of a fantastic horror flick!), and punch the result straight into my calendar as a reminder. Not only very accurate and very easy, but kinda fun. (It’s great for calculating, say, the next 3 refill dates out, vs doing that in my head.) What can I say? Not an absolute *must-have* like, say, text or maps, but I think I have a couple dozen apps or so on my phone, and only *really* make use of maybe 1 out of 10. And this is one of those. You’ll find your own uses for it, and end up really using it (and liking it), so go on, give this one a go!

Calculates Ranges, Add or Subtract Days…

Weeks, Hours, etc. simply.
Calculate down to the second, or forget about time if you’re only interested in working with full days and dates.
Intuitive interface, so there’s not much of a learning curve to navigate.
Thanks to the devs for keeping us end users in mind when developing the interface.

It's A Good App

But everytime I count it out myself your app always seems to be a day off from recording. I'm an aspiring author and when it comes to keeping track of ages and dates it's very helpful.

It seems like someone forgot May has 31 days not 30 in its in the learning rhyme because when it comes to calculating is a day too early you need to because I'm pretty sure someone forgot that May, July, August, October, and December have 31 days total and whatever is causing it to glitch needs to be fixed because it's at least a day off.

When I started writing this review I was aware I don't count very well but now I'm counting correctly and the Problem is occurring somehow it's off in its off by a day when it comes to June 1st. Please fix this before it causes others more stress
