I used to use this calculator everyday for work and now all of a sudden there's ads every single time you open the app. So if I'm going back and forth between this app and another one on my phone to add different times I get an ad every time I reopen this app, it's ridiculous. Going to have to uninstall and find another app if this doesn't get fixed.

Hi Megan! I know that ads can sometimes interfere with the user experience, but they are essential for the app to be free. There is an option for those who prefer an ad-free experience, you can get more details on the “Remove ads” screen. If you have any questions, just let me know.

Good time calculator. I wish it would work with a.m. and p.m. as well then I could give it a full five stars. Thank you for your quick response about the am pm location in the options section. I was hoping for something more in the face of the calculator that you could choose from a.m. or p.m. or military time? when starting the calculation However, I do want to say that you have a really good time calculator clock. it shows that you have put a lot of quality time into putting this together.

Hi, you can go to the app settings and change the time format between 13:00 and 1:00 PM. The settings are located in the 3-line button. If you have any questions, just send me an email; my contact information is on the "About" screen.

hardly ever use it. BUT when the moment arrives to do an equation with time and not the normal 10's and 100's it's my best friend ever. I love it.
