### 5/5 — 15 years

*2026-02-07*

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.

### 5/5 — Very lean and to the point

*2022-08-21*

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

### 5/5 — Love it Long Time User

*2020-12-08*

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.

### 5/5 — Owner

*2020-10-23*

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

### 5/5 — 5 stars for the app, 7 stars for the developer

*2019-10-24*

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)

### 5/5 — AWESOME!!!

*2019-07-15*

I have been using this invoicing app for years, it is, by far, the best time billing app out there.

### 5/5 — A great program for me.

*2019-06-24*

I used to have a terrible time recording my hours and then spent hours preparing the invoices. 

Often I would have to spend a very long time at the end of the month looking through my emails and texts and telephone calls and try to re-create my billing detail. I know this process missed many legitimate hours to be billed. And also just made me angry at myself for being disorganized.

But with Timewerks it’s ridiculously easy.  I find it so good that I’ve never shopped competing apps. So I can’t claim I’ve tried them all and this is the best. I just know it’s wonderful.

Do, however invest in the remote back up option from Timewerks so that if anything ever goes wrong with your iPhone you haven’t lost that critical data. 

And, by the way, this is not One of those fake paid-for reviews. I’ve been using this app with delight for about the last four years.

### 5/5 — Indie dev app dream.

*2018-10-05*

I love it.  I’ve invoiced my hours in this app for 6 years.

### 1/5 — Lack of customer support

*2018-06-02*

I used this product previously and recently downloaded it again for another project that I’m working on. I paid for the year upgraded service and went to do an invoice for a client and something went wrong. There is no phone number to call and I really need to talk to someone as soon as possible. I had tried to email support and it took a week for someone to get back to me and what they sent was a templated response that didn’t answer my question and wrote back again and asked for a customer service phone number and no response. Very frustrating.

### 5/5 — Great app!

*2018-01-15*

I’ve used this to manage my LLC for 8 years now. Solid tool and when I’ve had a question, great customer support. Has made invoicing and hour tracking a breeze.
