The FIFA World Cup mobile app is plagued with crashes and may encounter problems in congested usage periods during the tournament, according to Compuware.
"The app crashes continually occur at three separate locations: when trying to view Brazilian team information, randomly when checking for fragments, and when trying to reload following a failure to load news on the initial page," said a statement from the US software vendor.
The findings were announced in technical strategist Klaus Enzenhofer's post on a company blog.
"Let’s just hope FIFA is able to iron out these teething troubles by the time the World Cup kicks off, or there are going to be some very disappointed football fans out there," said Enzenhofer, who works at the Centre of Excellence at Compuware Application Performance Management.
The crashes are caused by "an empty array, a deprecated library and an unknown developer issue that appears to involve the database", according to the multinational technology firm.
Enzenhofer said he understood the pressures on app developers: "The reality is that mobile apps are incredibly complex, but developers are often being forced to rush them out in ever shorter timescales to keep up with market demands.
"As a result, there often isn’t the time to test them as rigorously as applications should, and indeed would have been in the past."
Compuware stated the problems were identified by the Auto Instrumentation feature within its Mobile Real User Monitoring product.
