  • 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!
  • Disappointed

    This app would not restore purchases. I am not buying a second time. Fix this App. Would NOT Recommend this app at this time

  • 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

    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.
  • Just what I was looking for

    By Aikijoe
    Beautiful app, and actually the only one I could find in the App Store that allows you to add hours to a day and will tell you the time of day it would be into the next day. Great job!
  • No seconds?

    By rochelle_22
    Love the website, but this app does not have seconds on the original time. Therefore adding/subtracting seconds is meaningless. If I had known that, I wouldn’t have purchased no ads...
  • Doesn’t include all functionality of website

    By WolfSnapCom
    This app is really nicely done, but, it’s missing things like “weekday only” calculations and other niceties that’s on their completely free website. Hope they can add those features, which would make this, easily, a 5-Star app.
  • Good, with limitations

    By wtxvolunteer
    As previously mentioned, the only thing holding this app back, is the ability to only go back to year 2000. Should have never been an issue.
  • Cannot do start dates earlier than year 2000

    By ptoxiq
    Such a limitation is absurd considering the intended purpose of this app. Yes, developer intends up update regarding this limitation, but I am uninstalling meanwhile.
