The number in the app is gross revenue for time online. It is not a wage, and treating it like one is how drivers end up working sixty-hour weeks for less than they made at a job they quit.
Real hourly is gross earnings minus fuel, minus per-mile depreciation on your vehicle, minus a maintenance reserve, minus the tax you will owe as a contractor, divided by every hour you were unavailable for anything else — including waiting and repositioning.
Use a conservative per-mile vehicle cost. The federal mileage rate exists as a deduction, but your actual cost on a paid-off economy car is lower and on a financed SUV is higher. Know which one you are driving.
Once you run this for a month, the pattern usually shows up immediately: two or three time blocks carry the whole week and the rest are close to break-even. That is the decision the math is for.
