“A good indicator are the app reviews that users post on the Google Play Store or the Apple App Store, “says Matthias Becker from Chip magazine. The reviews deal with an app's strengths and weaknesses from a user's perspective.
Markus Burgdorf from the consulting firm App Agency also ratings these ratings to be valuable. “It helps to look at the screenshots, read the description of the app and read the reviews carefully,” he says. Of course, one should be aware that some reviews can be fake.
Another way to evaluate the trustworthiness of an app. “A calculator app can be good, but if it wants to access my address book I will not install it,” Becker says.
Sven Rill, professor of mobile computing at the University of Applied Sciences in Hof, Germany.
“A good app makes it everyday everyday,” he says.
“A good app makes it my everyday life easier and does not make it any more complicated, “Burgdorf says.
“There are often a large number of applications that to 80% are offering the same functionality,” Rill says. “
The application should match its stated purpose, the professor says:” For example, a shopping list does not need a navigation function. “
Often you just have an app. But you should be aware of pitfalls – “Rill warns.
There are also apps that promise to unlock certain features in return for a good rating or which make money from users, says app expert Burgdorf. Especially in games, there's a risk of spending too much on in-app purchases.
And there's also the danger of fake apps. “Successful apps are often faked,” Burgdorf says. In those cases, the name of a genuine product is slightly changed and screenshots and descriptions copied from the original listing. Such apps are often malware trying to collect smartphone data or make money by sending expensive text messages. Becker advises caution if an app sounds too good to be true. “If an app promises to make a mobile Internet turbo-fast, you should read it carefully first.” – dpa
