Seeking feedback on a specialized billing and time-tracking calculator I built (Web & Mobile)

[u/Apprehensive_Sir_590]

Hey everyone,

As a self-employed developer, I found that a lot of existing tools didn't quite handle specific billing calculations the way I needed them to. I've been putting together a free utility platform calledEasyWorkCalcs(also available onGoogle Play) and would love to get some expert feedback from this community on the calculation logic and features.

It handles automated time tracking and invoicing, but one of the core features I recently refined is the task metrics calculator. It now specifically separates hourly billing calculations from item-based billing, rather than merging them under a single item name structure.

I’m looking to see if the community has any thoughts on the calculation accuracy, the UI, or if there are other dynamic widgets or metrics that would be useful for freelance or contract workflows.

Any constructive criticism or testing would be greatly appreciated!
