User reviews

15 years

I began using Timewerks when I formed a consulting firm. I needed an app to track hours so that I could accurately invoice clients. After 15 years I still use this app and have never had a client question where I spent my hours as everything is detailed. All of my invoices are on the cloud I don’t usually accessed. The ability to keep track of hours and then in a matter of minutes create and send an invoice is one of the strongest features of this app.

Very lean and to the point

So many other apps, but I keep coming back to the focused, functional, simplicity.

Love it Long Time User

I’ve been using Timewerks for many years to efficiently bill my clients before I even drive away, invoice, send by email and the bill is in their hands in 10 seconds. It’s simple too. Not a bloated pig with features you never use. This thing takes care of business.

Owner

This is the best program I have. I use it every day in my business, keeping up with my time and materials. I’ve started using it in 2012 and haven’t stop, thanks

5 stars for the app, 7 stars for the developer

When I first bought this, it did not fit my working style, so I emailed the developer. Steve Orth responded quickly, and acknowledged my requests for changes. I asked for control of invoice numbers - done. I asked for more control of timers (minutes instead of quarter hours) - done. I wanted to be able log the start, take notes, and close off the service call - done. I asked for number of running timers on home screen - done. I could go on, but Steve is bringing changes in very rapidly, and improving this app faster than I really expected. A smooth running, useful app, reasonable price, and a communicative, co-operative developer. (and I paid $70 for the same function on a windows pocket mobile phone, but I could not email invoices from the phone!)
A number of years has passed since I wrote the first part of this review, and I am still very happy with the app (and the developer)
