It fulfills everything from automation to manual performance

The most valuable features of the product are the performance parameters it gives us, as well as the seamless connectivity with our automation suites. I am also pleased with the continuous enhancements made to HeadSpin. There have been many features added since we started using the product, and all of them are useful.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage

I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

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

Pros

"Large companies and enterprises are using this product."

"The most valuable feature of HeadSpin it's the integration with other solutions; it is great, and I can search for an element or do a quick debugging on the application right on HeadSpin, which is very useful."

"The most valuable feature is that this is the first connected intelligence all-in-one platform."

"HeadSpin is highly advanced; it has got all the performance structures to provide visibility into how my app is performing in the real world and helps to identify the gaps."

"HeadSpin allowed us to manage remote work during Covid, enable continuous automation execution, and facilitate collaboration between various departments (product managers, developers, etc..)"

"The initial setup of HeadSpin was very easy and user-friendly, and it was easy to configure and write a script to achieve the desired outcome."

"The most valuable features of the product are the performance parameters it gives us."

"It has an interesting feature called AV box testing. A lot of companies that are in the OTT segment don't really understand what their streaming is like. They can't test for streaming quality. There are restrictions where you cannot simulate live streaming. For example, on Netflix, you can't simulate how a movie is being streamed on a remote device. That's why HeadSpin has got this AV box testing feature. It is a patented feature. They send an AV box to your location, and you can test live streaming, which is something that no other company does."

More HeadSpin pros

"The solution is very easy to understand and has a user-friendly UI."

"LambdaTest was handy and easy enough to save us a lot of time, effort, and money."

"It is a scalable solution."

"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."

"LambdaTest proved to be a savior for us here, as one platform does the job!"

"The primary feature that has significantly improved our test execution times is automation."

"The slow nature of a cloud platform was compensated with parallel testing, and now we are able to finish our testing job faster than it was before COVID."

"Stability-wise, I have not experienced any downtime or other performance issues."

More TestMu AI (Formerly LambdaTest) pros

Cons

"They should automate their onboarding. A lot of things are still manual. They can create a video assistant or something like that to completely automate the entire process."

"HeadSpin needs to improve the hardware. With the mobile, the battery life reduces and must be continuously charged."

"Support and pricing could be improved."

"HeadSpin could improve on the user interface because it is very poor."

"If you want to do some testing or check the devices manually or check the application in a particular device manually, it is really laggy. That's a disappointment because sometimes we would like to do manual testing when our local devices are not available."

"Sometimes, devices go offline and some features are not functioning on some devices, specifically on iOS."

"HeadSpin could improve on the user interface because it is very poor. The checks that are done on the iOS devices are very difficult, but for Android, it runs great. For all iOS devices, the user interface and how it interacts with the device are very poor."

"There is a great scope to improve professional services; the time to deploy is quite long, and while they can set up automation through scripts at this stage, they are very expensive."

"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."

"If possible to simulate the finger pinch, it would make it more realistic."

"Their smart testing module needs improvement."

"The analytics over the automation dashboard can be more intuitive."

"I think Lambdatest is a valuable tool for our team and things that have room for improvement would be mobile app testing, as it can be an important addition to the tool."

"Load flow compared to other stacks needs improvement."

"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."

"I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow."

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

"I believe the licensing cost is cheap because it's a total solution, hardware, license and software."

"It's not cheap, but there are a few different packages and different prices for enterprises with different product versions."

"We have a yearly license for 16 devices."

"It has a yearly license. There is no other option. It is expensive. There are a lot of other cheaper players in the market, but it is like a Mercedes. You pay an extra premium for it, but you get the benefits. I would love to see them come up with project-based costing. Companies that are low on funds or new-age can do with pricing that is easily digestible. They can give them a pricing model for three months. They can provide a startup package."

"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."

"I used the product for free."

"The tool is not cheap, but it is not expensive."

"This is an affordable product."

"It is free to start, which means you can actually see how it works and then take the decision to buy."

"The pricing could be made cheaper."

"LambdaTest is priced well, which is why we migrated to it."

"LambdaTest's pricing is cheaper than that of other similar platforms."
