Infact is claimed to be the best app for testing facts.

The statement that 'Infact is the best app for testing facts' is subjective and cannot be verified with factual evidence. 'Best' is an opinion rather than an objective fact and depends on personal criteria and preferences. No additional context indicates that Infact is ranked or validated as superior among its peers. Regular testing apps, such as Selenium and TestRail, are more commonly referenced regarding efficient software quality assurance. Hence, the claim remains subjective without specific, supportive data.
