I didn't encounter many components that were annoying. One main area of frustration was finding data. When wanting to find data about clicks on a specific UI feature, element, or button, sometimes the objects were not named in a descriptive way. That was our problem on the implementation side, not Heap's. I also found that the analytics dashboards in Heap couldn't be customized as much as desired. I couldn't adjust the charts in the widgets or the settings on each widget to the level wanted in either data granularity or physical size of the widget on the dashboard page. Additional flexibility in dashboard building and widget building would be beneficial.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"What I like best about it is the session replay feature. It saves a lot of time. I don't need to go and debug or replicate issues multiple times. We can go to the session replay for a few minutes. We can ask when the issue occurred, go to that time in the replay, and see whether the user made a mistake or if there's an app caching issue. That has been very helpful."
"With its ability to easily define user events, one can easily detect how one can better optimize one's product to drive better retention and feature use."
"The initial setup process was straightforward."
"An immensely useful feature is the retention graphs with the ability to generate retention data for individual features."
"Heap enables one to easily track how customers use one's applications on both the web and mobile."
"The reporting has helped improve investor relations and let us quantify our growth and progress with ease."
"Discerning application and UX weak points, driving better user retention."
"Heap enables one to easily track how customers use one's applications on both the web and mobile."
"Dead simple A/B testing with no code knoweldge needed."
"Optimizely can work for a lot more things than only testing; it is a pretty easy yet powerful tool."
"Optimizely is a great product that has inspired a great community and is the standard for A/B testing."
"Customer service is wonderful."
"ROI: Infinite! (Got 3X conversion improvement using suggestions given by the product during the free evaluation period)"
"Customer service is the best in the testing industry; transparent support along with a very strong community."
"Customer service is excellent!"
 

Cons

"My experience with pricing, setup cost, and licensing has a problem because when you are collecting more and more data, it becomes more and more expensive, and the ten thousand free sessions can be burned really fast, after which it became expensive."
"Based on my experience, there's some room for improvement. The application is a bit slow. Also, I must read through old documentation when I need to check for new features. It's not very user-friendly. Once you're in the application, it's easy because it has many features. But for first-time users, you have to go through all the documents, which can be challenging."
"It's more expensive."
"Their analytics could be more user-friendly."
"I would rate Heap's scalability around 6 out of 10 because we are still not completely familiar with it."
"The product could benefit from more advanced UI features."
"Their analytics could be more user-friendly."
"I also found that the analytics dashboards in Heap couldn't be customized as much as desired."
"Better communication with 3rd party implementation"
"Exporting statistics provide more statistical data."
"Verifying goals could be easier."
"There were previously issues with experiments saving as expected in Classic."
"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
"When testing images or anything involving JavaScript or more than text, they can really slow down the load performance of a page."
 

Pricing and Cost Advice

"Heap's pricing can be heavy according to the usage and requirements for control billing."
"The solution is expensive."
