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.

I'd like an option to use : as a button, I do payroll and while this app makes things faster, it could be even faster that it is because of the extra steps you have to take with the Hour and Minute buttons. Thatnk you for updating the app with my other suggestions, this was very helpful! I'll give a 5 stars but keep working on my ideas please.

Hello! Now in version 1.2.4 it is possible to set in the settings the option "Units to ignore in the result", so for your need, you just need to choose the option "[d] Day" to be ignored. If you have any questions, please send me an email. Thanks.

Finally, all my whining and crying has paid off. There is now a memory function! It was what kept this app from being the perfect time calculator. Thank you developers! You now have some of my hard earned money. (But only a little bit. As if this writing, the price is very reasonable.) 👍
