Simple app that gets the job done.
No fancy features. Just a good way to calculate earnings down to the second. I use it when doing work at a client's home since I charge by the hour for most in-house services. I just add in the trip fee at the end and I have my number for what I will charge. I'd recommend downloading the free version just to get a feel for how it works but I have read that it is locked down at timing only $10 per hour so to change this you must pay for the full version which in my opinion is more than worth it. Does the job very well.
