Time tracker tool

We are building a MVP of a time tracker tool called TimeTix.
I know it's an existing tool in many places, but all of the tools i have seen are really expensive for what you can do or they are useless.
One of the best (and easiest) to use was ActiTime (i currently have a software company and it was a tool we really used). But nowadays it's really expensive for small companies like us.

A lot of large companies also use time trackers similar to ActiTime (i know this because at least 4 of our clients use it).

We are thinking of launching the MVP for testing in a month. The URL is currently live but we are working on it: https://www.timetix.net

For people:
After the MVP and product launch, the idea we are exploring it's using it to track personal time too. Productivity for your goals. This would be a V2 MVP. We want it to be mobile, where you can easily press a button and say what were you doing and where to add that time. Similar to a finance planner, but with time to your goals.

What do you think about this?

Thanks!
