I was looking for an easy-to-use, minimal learning curve, non-bloatware time/billing app. I checked out several titles (somehow overlooking OfficeTime at first), but could not find the "right" app...either functionality that I felt important was missing (e.g., how to handle overtime billing on a retainer), or I discovered spotty functionality in the demo (e.g., iCal integration that didn't work as advertised).

In OfficeTime I found *exactly* what I was looking for. Their marketing message "intuitive and deceptively simple" is dead-on.

Features I love:
1. Easy project setup and selection. The menulet is great!

2. It syncs with iCal both ways, so you can easily tag an appointment for time billing under a specific project in OfficeTime.

3. Flexible rate management (e.g., I have different support packages that provide up to a specified number of hours per month for a flat fee, and then overtime is discounted off my regular hourly rate). OfficeTime handles the set up, use, and reporting on this need fantastically.

4. A useful little "remind me" tool.

I use a separate accounting package, so I don't really use OT's invoicing capabilities, but the reporting is quite comprehensive and useful.

Feature requests:
1. Direct Google Calendar integration. It syncs seamlessly with iCal (as does Google Calendar via CalDAV), so iCal is suitable middleware as long as you remember to launch it to sync updates between Google Calendar and OfficeTime.

2. iPhone app or web interface
