What do you like best?
I like a lot about Intervals. Most important to me:
• Ease of use. I work with contractors, as well as employees, and I don't have a lot of time to train everyone how to use our project management system. I've been using Intervals for more than a year now, and everyone who has tried Intervals has been able to start using it almost immediately, because it is simple to navigate (and has very brief, webinar-style introductory videos, as well as straightforward text help, if anyone is confused or wants to learn more).
• Price. I pay about $50 a month, which is very reasonable given all of the features of the software. Most of the comparable software that I explored either lacked features I wanted at that price point, or did not give me enough room to track all of my (25 or so) complex projects that I simultaneously need to follow.
• Flexibility. There are plenty of options that allow me to customize Intervals to meet my needs (adding project status options, categorizing projects to meet our current internal systems, etc.).
• Features. There is a wealth of reporting and queueing options to choose from. I use most Intervals features regularly, but I still haven't found the time to use them all. You can right-click on many pages to access numerous shortcuts that make it easier to update projects and tasks (e.g., to change project status or deadlines without needing to visit a different page). It is good to know that I can grow into the unused features as needed. It is even possible to allow clients to access the system. They also have a plan each quarter for phased-in improvements that they share with clients.
• Customer service. Intervals staff have responded to me immediately when I've needed help — every. time. They've also responded in a helpful, thoughtful, thorough way to my questions and even to some of my feature suggestions, which they really do read.
• Time tracking. A lot of other systems I looked at charged extra for this feature and/or did not offer a robust enough solution to meet all of our time tracking needs. Very easy and convenient to use.
What do you dislike?
• The mobile interface is accessed via browser (rather than an app) and is not as user-friendly as the desktop version. Intervals reports that mobile enhancements are in the works this quarter, so that might improve. I've been able to get what I need from the mobile interface (on my iPhone) while I'm on the road, but I don't enjoy using it on anything smaller than my laptop, and it could be a deal-breaker if you often want to use the system on your cell phone.
• Its graphic design doesn't make me 'ooh' and 'aaah' the way that some other time management sites do. It is well-organized, it just doesn't look as cool as some other project management tools do. This doesn't seem to be a high priority for the company. Since it isn't a top priority for me, I don't mind this much—I get lots of bang for my buck in other areas.
• It doesn't integrate with as many other services as some other top competitors. This might be an issue for some folks, but it isn't huge for me, because Intervals already does most of what I want it do.
• The file management system isn't quite as convenient as I'd like. Intervals did add drag-and-drop last year, which I am thankful for and is an improvement that was at the top of my wish list, but it isn't as seamless as other drag-and-drops that I use. I also would like to be able to organize documents a little more thoroughly. For instance, while documents can be assigned to each project and task, it would be nice to be able to organize those documents into 'folders' rather than having them in one long list. Again, though, this isn't a major issue, and you can add tags and notes to files to make them easier to find and identify.
All of the above is just to say that there are features I'd like to see added or improved, as with just about any software I've used, but I've weighed these issues against other systems, and the pros far outweigh any cons I can think of, in my case.
Recommendations to others considering the product
Note that while some systems, such as Basecamp, offer a comparable number of projects to be active all at the same time, Intervals allows tasks to be assigned within its projects, so that you are getting more bang for your buck in this area.
What business problems are you solving with the product? What benefits have you realized?
I purchased Intervals for my small business to make it easier to track and assign tasks. 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. I looked at a lot of other systems, including BaseCamp, Asana and a few others that are commonly recommended. Intervals was the best fit for what we were seeking. If Intervals has the features that you are looking for, I'd very highly recommend it.
Full disclosure—I may get a small perk for being among the first Intervals customers to submit a review. That isn't contingent on writing a positive review and I would have written all of the above regardless. After using the service for more than a year, it is hard to imagine going back to life without Intervals.
