Great LARGE Display but

Great simple large display. Only a few issues, and maybe the 2nd is my stupidity.
1. The alarm would not work, until I thought, hmmmm, maybe I need to allow notifications. Yup. Now see that on this site, but the app should prompt you when installed to do this, like other apps. So many people have downgraded the ratings because the alarm “doesn’t work” - it does.

2. Am I missing something on the screen that tells me the alarm is on. When you set it, a pppup appears, but right over the clock so you have to dismiss it to see the time. Then nothing. Unless I’m missing something, should have at least an ASet somewhere, or open up that window after you set it somewhere in the corner of the screen. It is set, but feel uneasy never knowing night after night whether it’s set.
Again, unless I’m missing something - maybe someone can educate me, in which case would have 5 stars.


Bright ads flash all the time

I am deleting this app. I wanted to use this app on my night stand. But ads keep flashing on and off and waking me up.

I’ve heard of greed. But c’mon people. I’m not going to wake up in the middle of the night, because a new ad flashed on and then get the sudden urge to buy whatever it is your app is selling, before going back to sleep.

Most of the other free clock apps turn off the ad banner after a few moments of inactivity. I have yet to see the ad banner in this app go off. It just keeps flashing new ads of different colors and brightness. Shut off the ad banners after 30 seconds of inactivity. On second thought, just keep on doing what you’re doing, because I’m deleting the app, so it will make no difference to me.

cls boise

Almost there!

I like this app quite a bit: it’s not cartoony or retro like most other apps with a large clock for quick view. But I wish there were an option to remove the huge A.M./P.M. part that is unnecessary and takes up an inordinate amount of the screen. Also, I hope there’s a way to make it override the phone’s auto-sleep function, making the app much more useful. Keep going!
