Data insights have improved user journey analysis and now call for better AI-driven dashboards
The best features Heap offers are automatic event capture, funnel analysis, user journey segmentation, and session replay. Heap has improved data-driven decisions, enabled faster issue discovery, increased conversions, and delivered overall better user experiences, which has impacted my organization and our product goals. Heap is excellent if you are running a product team and want to understand user experiences and how users move through the product workflow. It excels at generating predictive analysis on user behavior, identifying key drop-off rates, and measuring feature adoption. The session replay feature reduces troubleshooting time and accelerates data-driven product decisions. Heap helped me identify where users dropped off in key workflows, enabling user experience and UI improvements that increased feature adoption and conversion rates. Automatic event capture saved significant engineering time by eliminating manual tracking. The session replay feature also reduced troubleshooting time and accelerated data-driven product decisions.

Quotes from Members

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

Pros

"Heap eliminates the guesswork of funnels, directly resulting in higher conversion rates and revenue."
"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."
"Heap enables one to easily track how customers use one's applications on both the web and mobile."
"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."
"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."
"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."
"The reporting has helped improve investor relations and let us quantify our growth and progress with ease."
"Customer service is wonderful."
"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 excellent!"
"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."
 

Cons

"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 pretty costly, and they use the common model of impressions."
"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 like to see improvements in Heap including more dashboard customization, better predictive analysis, mobile support, more AI insights, and greater reporting flexibility."
"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."
"Data privacy is crucial, as my organization has experienced real-time examples where thousands of patients' sensitive data have been compromised."
"I would rate Heap's scalability around 6 out of 10 because we are still not completely familiar with it."
"Better communication with 3rd party implementation"
"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
"Verifying goals could be easier."
"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."
"Exporting statistics provide more statistical data."
 

Pricing and Cost Advice

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