The Intervals team listens when we ask for specific features, and updates the software to make it better and better. I love how easy it is to use and to keep track of our projects and tasks.
Nice API, you can take all your data and do whatever you want with it. The request management system is pretty good.
Its giving you a chance to try the software before buying it, which is very smart because you will like the software and will ending buying it.
Intervals introduces new features every quarter or so one of the latest is adding files through drag and drop. The lack of drag and drop used to be the biggest con for me, since I upload files often.
We previously had a system that no one (including me) used because it was not at all intuitive and was a poor fit with what we needed.
We have integrated it via its API with our in-house issue tracking software: the integration was a little awkward but once set-up hasn't given us any problems.
