Feedback wanted: would solo cleaners log visits to compare earnings per client?

I'm building CleanLedger, an early iPhone prototype for independent cleaners. It records cleaning and travel time, direct costs, invoices and payments received, to compare hourly earnings before tax and owner labor and see unpaid balances. Records stay on the device; no login is required.

My biggest uncertainty: is the benefit worth entering each visit?

If you run a solo service business:

1. How do you track this today?

2. What decision would these numbers help you make?

3. What would make you stop logging?

4. On a 1–10 scale, how useful is the idea, and why?

I'm the builder. TestFlight is still pending, so this is prototype feedback, not a public launch or download invitation. No payment or positive reviews requested.
