aTimeLogger Time Tracker 4+

I've been using this app for years and the most recent version is terrific! It took me a little while to figure out the most useful categories to create and how to group them, and sometimes I still tinker with them, but the app is very adaptable, and it's stayed useful for me through several major life changes. The goal and reports options are especially helpful for productivity and personal satisfaction but would also be useful for someone who billed hours to different clients or wanted to track hours devoted to different parts of a job description. My only wish might be for some fresh appearance options--new themes or icons for activities, that kind of thing. I plan to use it for many years, and I would hate to get bored.

UPDATE: I just had my first technical difficulty, but my experience with customer support was AMAZING. I heard back within an hour of sending the message, responses were clear and courteous, and the whole problem was resolved within 12 hours. It might have even been faster if I'd been closer to my email that day. A+

I couldn't be happier with this app. Been using it for years. It's very customizable, and perfect for tracking your time, whatever that may be. Very easy to use and super easy to create reports you can then email. I use it to track hours for my job. I can record everything I did that day, and if I forget to start or stop my time it's simple to go in and correct it. I just create the report and email it to myself and my boss. Works perfectly!
In addition to a great app the customer service is beyond outstanding!! I ran in to a serious problem that could have spelled disaster for me. I emailed them not expecting a response, and received an email back in less than a hour! He proceeded to walk me through several steps until the problem was solved! They genuinely care about the customer and I can't thank them enough!

I’ve used hundreds of apps over the years. This is easily in my top 5. It is EXTREMELY customizable and allows multi-level tracking to whatever detail you want. I have it on my primary complication on my Apple Watch so I can switch activities with 2-3 taps on my watch. Optionally, it will periodically remind me what I’m currently tracking in case I forget to switch to a new activity. It provides powerful graphical and text reporting with good selective filtering. It is virtually bug free and works as advertised. I can’t comment on their support because I’ve never had to use it. They provide screenshot and video user instructions. Initial setup is straightforward if you first watch the instructions to understand: 1. Groups, 2. Activities, and 3. Adding Activities. I would give it 10 stars if I could.
