Heap

The feature set makes it very easy for use by a cross-section of disciplines within your organization. It does not require lengthy training to become proficient in the tool, but Heap does offer a lot of resources to help individuals learn at their own pace/time.

It requires a bit of set-up out of the box in terms of the reporting/analyzing piece of the business. You have to create events and map pages and that can be a bit time consuming, but once you do it, it doesn't have to be updated again.

By far the most impressive feature is the fact that from the moment you install heap on your website you can virtually track anything that happens, regardless of being in the past. That is, even if you don't configure anything, it already records everything so you can retroactively analyse funnels, clicks, user behaviours and much more.

Another feature that is well implemented is the flexibility to customize segments and events. The tool is designed so you can make your own building blocks for your dashboards, making it a very powerful ally when it comes to understanding what your users are doing in the platform. For example, in most tools it's a headache to even think about analyzing the impact a new feature has on the retention of a segment of your users, especially if didn't think about it when developing the feature. With heap, not only it is possible but it is also very simple and quick. For the first time, our team can think about validating business hypothesis without needing any prior coding or preparation, and even test them long after the features have been released.

If your frontend programmers are not completely aware of the impact their changes might have, it can be very easy for them to erase css classes and/or change the html structure, which can have a big impact on the events (and, consequently, dashboards) on heap. On the long term, this hurts. Even though heap has put in place warnings when events stop triggering, it is still hard to maintain if you don't bring your developers on board to avoid making structural or class changes. The alternative might be to add IDs to every button, link, page, section, etc, so to ensure the events are kept alive, but that is also not a good option. If you don't expect your webpage to change that much, then this is not a problem.

The amount of configurations and customizations in the dashboards and reports is limited. There should be a more powerful reporting tool, with more (and more customizable) charts.

Easy to implement, compared to other solutions.

Time-consuming to set up specific events and segments.
Only exports up to a set number of rows, so you need multiple exports
No royalty for their long-standing customers.
Company staff not good at communicating

Thanks to Heap we've been able to track every single step of our user's journey. We've made an incredible amount of improvements and have found bugs in places we could have never without this tool. It even makes Google Analytics look average. Absolutely wonderful piece of software

I can't say using and implementing heap is the easiest thing. However, there are many tutorials, they have a great onboarding process and their customer service is magnificent. I assume you can't expect a tool this good to be the easiest to use. It needs some training!
