Outer Level today announced LicenseKeeper, a new software license manager for Mac OS X. LicenseKeeper is able to store both serial numbers and license files along with receipts, email and other related files. In addition, auto-scanning of email captures serial numbers and eliminates tedious error-prone data entry. LicenseKeeper is priced at US$19.95 and requires Mac OS 10.4 or later. A free trial version is also available.
