Intervals
The FunctionFox Alternative
We know what it’s like to keep one eye on getting work done and the other on getting paid. Intervals is the best FunctionFox alternative that will improve both your productivity and profitability.
How are Intervals and FunctionFox Similar?
Both of these agency project management applications are used by creatives who need to track time, manage tasks, and invoice clients — all while delivering projects on time and under budget. On the surface, both applications advertise a list of features that might seem similar, however, there are several differences that make Intervals the better choice.

How is Intervals Different?

More Generous Document Storage
Each of our plans provides a generous amount of document storage, so you won’t have to worry about running out of space in the middle of a project. Document storage is included on all plans at no extra cost, making Intervals the ideal FunctionFox alternative for keeping files organized. Attach files to projects, milestones, or tasks, and provide your team the supporting documentation they need where they need it the most.

More Flexible Task Management
Our flexible task management platform enables you to implement any workflow you want — tasks can represent bugs, to dos, tickets, stories, or just plain tasks. In contrast, FunctionFox takes a more rigid approach to task management. And, only Intervals records a meticulous history of every task, so you can stay focused on the bigger picture while collaborating with your team. Never again wonder what work has already been done, or what you should be working on next.

Time Tracking for Teams
Our time tracking tools were designed to mesh with the task management process, so you know exactly where your time is going and keep your projects on schedule. The ability to view currently running timers provides insight into what your team is working on at that moment. And, flexible reports help improve productivity by offering both high level overviews and low level analysis of your team’s efforts.

Less Restrictive Pricing
Our monthly plans give you room to grow. Intervals is the only FunctionFox alternative that includes unlimited users on every plan (except Lite). Throw as many resources as needed at each project without having to worry about incremental costs. Because when you are up against a deadline, your project management application is the last thing you want getting in the way. Our monthly plans are tiered based on the number of active projects being managed — completed projects don't count — so you can re-evaluate your needs and upgrade your account as your agency increases its capacity to take on more work.
What Do Our Customers Think?
Intervals is a very well thought out tool. We’ve used a number of task management and team organization packages and none have come close to providing the necessary functions for managing pro projects for high-end clients.
