Date and Time Calculator Pro

Hello - I had to reinstall my phone after it crashed. Even tho I paid for this app, it is unwilling to restore my purchase. I didn’t want to post this issue here but cannot find the developer’s contact info w/o going thru Facebook & I don’t have a FB acct. Mr./Ms. Zhang, can you help? I love this app & will replace this review & star ratings after this issue has been resolved. Thank you.

As per the title, this app is one of my favorites. While I may not use it as frequently as other apps since it has a very specific utilitarian purpose, it has a prominent space on my home screen (first page) because when I do need to to calculate some date or time difference, this app is invaluable. As far as I’m aware, it’s able to do all the calculations relating to time and date that you’d need. I also appreciate that it has buttons to “clear” some text boxes so you don’t have to backspace-backspace-backspace and just get rid of your previous input with one press of a button. I also appreciate that for some text boxes, there is a button for “today” that inserts today’s date so you don’t have to do the whole scroll for the month, day, and year just to get today’s date. All in all, this is an A+ app that I’d very much recommend!

I am a 34 year old man living with Crohn's Disease. Unfortunately, the doctors have me on a lot of medicine. I needed an app so I know how many days I have until I have to have my medicines filled. I have tried a lot of the free apps that the App Store has to offer but a lot of them were too confusing. Very rarely do I spend any money on an app, but I went with my gut 😀 and bought the date time app. I LOVE this app. It is perfect for my needs and is very precise when making calculations. It will give you from, when, days, hours, minutes, seconds and so on. It even lets you put in dates from years ago! I even know how old I am to the tee when calculating the day that I was born until the present and it gives me everything and anything that I could possibly want to know. Whoever designed this app is extremely intelligent and has their head on right. Neat and fun app. I use it on a daily basis. It's especially useful when calculating the day when I have to call the pharmacy for a refill. The only thing I wish this app would do is to make a sound of when 15 days or 30 days, days of importance are vital. Other than that, perfect app!
