I like the app, because it allows me to keep track of *all* of the information related to my sites (unlike other similar apps that fail to track it all). The interface is clean and easy to use. I like the live URLs for each of the entries and the fields for username and password for each service.
However, I have one major problem with it:
There's no sync to iCal for expiring domains.
Sync to iCal and/or a smart folder for expiring domains is essential for an app that tracks that data. (Smart folders is a good idea in any case.)
A couple minor nits:
- The scrolling list of domains could be made larger, or at least have a preference for small/large icons and text
- Databases: it's not unusual to have multiple databases for a site, but Domain Brain only tracks one. Would like to see some facility for multiple entries here
- Passwords are visible once the app is open. Should have password hiding at the field level (perhaps integration with the Keychain)
- Tracked WHOIS info is sparse. Would like to see additional data pulled in, like Registrar and Creation Date, perhaps Registrant info
The nits wouldn't keep me from buying the app, but without some facility for identifying expiring domains, well, that's a deal-breaker.
