Provides actionable user behavior insights and improves feature prioritization decisions
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

"Discerning application and UX weak points, driving better user retention."
"An immensely useful feature is the retention graphs with the ability to generate retention data for individual features."
"Heap has positively impacted my organization because we no longer need to do it manually; it is fully done automatically."
"The initial setup process was straightforward."
"Heap has positively impacted my organization by improving patient experiences through different portals and applications, enabling patients to understand their surgeries and doctor prescriptions better."
"After using Heap, I started understanding the complete user journey because of its great feature, the auto-capture, which captures everything from seeing the ad to closing the deal."
"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."
"Heap eliminates the guesswork of funnels, directly resulting in higher conversion rates and revenue."
"Customer service is wonderful."
"Optimizely can work for a lot more things than only testing; it is a pretty easy yet powerful tool."
"ROI: Infinite! (Got 3X conversion improvement using suggestions given by the product during the free evaluation period)"
"Customer service is excellent!"
"Customer service is the best in the testing industry; transparent support along with a very strong community."
"Dead simple A/B testing with no code knoweldge needed."
"Optimizely is a great product that has inspired a great community and is the standard for A/B testing."
 

Cons

"Data privacy is crucial, as my organization has experienced real-time examples where thousands of patients' sensitive data have been compromised."
"The product could benefit from more advanced UI features."
"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."
"Their analytics could be more user-friendly."
"I also found that the analytics dashboards in Heap couldn't be customized as much as desired."
"I would rate Heap's scalability around 6 out of 10 because we are still not completely familiar with it."
"It's more expensive."
"Verifying goals could be easier."
"Exporting statistics provide more statistical data."
"Better communication with 3rd party implementation"
"When testing images or anything involving JavaScript or more than text, they can really slow down the load performance of a page."
"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)."
 

Pricing and Cost Advice

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