About us


The inspiration for Calendar Clock came from a neighbor with a mother with dementia. He was looking for a day clock to assist his mother, but found it unnecessary to purchase an expensive clock for this. "Why can't I do this on an old tablet?"

After releasing the app, there was more interest in the app. I received numerous emails with suggestions for improvements and new features, and since then, I have been able to develop the app further with my users to create the most feature-rich and user-friendly day clock on the market!

Users were so enthusiastic about the app that they spontaneously asked if they could help translate the app into their language. That is why Calendar Clock is now available in 26 languages!
