If you’re looking for a agile software development, then the pivotal tracker by Camel Punch is the tool to get. They use this tracker to keep communication between clients and developers as simple as possible. It also helps keep everything organized and clean to avoid chaos. And best of all, it helps organize time to show just how successful they are with this.
The Pivotal tracker just makes it easy for all parties. There are softwares by other companies who promise you one thing or another but end up disappointing. The Pivotal Tracker by Camel Punch is by far one of the best I have seen.
