  • It’s Great When It Works

    By damacadocious1
    I have used this app for some time and find it a tremendous asset when it works properly. It hasn’t worked correctly since IOS 12 was released. The search option doesn’t display character input. The app still performs a search, but the field is blank and search results are inaccurate. I have submitted this issue in feedback several times, but it remains an issue.
  • Simple

    Does one thing, and does it extremely well. Exactly what I needed!
  • Stick with Their Website

    By kludge
    Website is easier and has more features. For example, if you want to add to the current date and time, the website makes it very easy to tap a link and set the current time, but this app makes you scroll through the hours and minutes since Noon, i.e. it doesn’t default to the current time. The website also has a ton of additional options/features.
  • visually unappealing

    By Blue Pine
    This app seems to work. But it is visually unappealing. I couldn't find any additional themes. So I may delete it rather than pay for it. I don't use apps with ads, and I'd be okay with paying for it, but the price is steep for such a simple maths app. And so ugly. I'm not going to pay such a high price for such an ugly and simple app.
  • Works most of the time

    By Netwitt
    The app does not calculate leap years correctly. The calculation should be ( year evenly divisible by 4 AND year is Not evenly divisible by 100 ) or year is evenly divisible by 400 then true else false. So year 1900 is not a leap year, 2000 is. 2100, 2200, and 2300 years are not leap years, 2400 is a leap year. This error will affect adding/subtracting days or calculating time crossing these dates. Otherwise for common calculations this app is great!

  • Nothing hete

    First it wouldn’t load. Then there was practically nothing I could do with this app. I did finally figure out how to create ‘day to day’ but absolutely NOTHING else. UI is abysmal. Deleting now
  • The developer doesn’t seem to support this app never got back to me

    By 133128677
    I purchased this app for its simplicity ( I really loved the web based app): I almost never buy an app with an in app purchase but since I liked this app but couldn’t stand the ads I did. The Ads never were removed from my iPad Air 2 running OS 11.1.2. This is the IPad I made the purchase on no matter how hard I tried. Including uninstalling and reinstalling to many times to mention always making sure I would press on restore purchase in the menu. I then installed this app on an iPad mini 2 and an IPad touch both with the same IOS and when I hit on restore purchase it said it was restored. I then shut down the app and started back up and no ads on those two devices. I could never get it to work on my IPad Air 2 despite trying for over an hour. I contacted tech support twice but never received an email back. So for now I am left with a bunch of ads with a program I already purchased and no help insight. This is an amendment to my first review Despite emailing you 3 times regarding my problem with advertisement after registering your program. I also am trying to have the charge I received credited to my account . I can not understand why you never contacted me. This has never happened to me before. Your program is having a problem removing the ads and it appears that you could care less. The developer is saying that the app wasn’t registering with the App Store and this is not correct. The fact is the developer knew that I had purchased the app and already had received credit from Apple after his app would not register on my main device. He asked for the receipt and when I told him Apple had already credit to my account he no longer wanted to see it. If the developer want me to email it to him I will be glad to do so. Better yet I could post it on his site if he would like that.
