There are two types of developers: those who make money writing code, and those who are tinkering around (think: college students toying around with Bash scripting)
The former, like most other professionals, will gladly pay for services and products that make their business lives better. And yes, while there will always be a small (and vocal) subset of professional developers who absolutely must write their own time tracking software, the overwhelming majority will just pay for something like Freckle. It just doesn't make any economic sense to write their own.
As someone who sells three products (a SaaS, a book, and a workshop) for consultants - mainly web developers - I can tell you first hand that the biggest win for targeting this audience is that they're easier to find and sell to. Getting, say, general contractors to find your product seems complicated and pricey. Developers, on the other hand, can be an inexpensive traffic source if you're doing the right things (like writing targeted content that gets indexed and shared.)
