Given the many different models of smartphone handset, in-house testing of apps is rarely effective at achieving comprehensive test coverage. There's always going to be some model of phone that disagrees with the app. Samir from Applause talks to Andrew about they can help with the problem.

Applause's approach is to crowdsource app testing to ensure that mobile apps are tested on as many different phones and tablets as possible. Applause call this "in the wild" testing - apps are tested on many different devices with combinations of RAM and CPU by real users on every day smartphones and tablets. These aren't pristine out-of-the-box latest generation devices or emulators. This real world testing greatly improves confidence that the app is going to work on as expected on full release.

Applause's list of customers is impressive and includes Google, Netflix, Coca-Cola and Amazon.
