Is Chrono app free?

I'm curious to know, is the Chrono app available for free download and use? Are there any hidden costs or fees associated with it? It would be great if you could clarify whether this app is truly free to access and enjoy, or if there are any restrictions or limitations that come with the free version. I'm interested in exploring the features and functionality of Chrono, but I want to make sure I have all the necessary information before I proceed. Can you provide some insight into the pricing structure and availability of the app?
