The average Briton has 27 apps on their phone, according to a new survey, but only uses six of them on a daily basis.
The study by Publicis Media polled 2,000 people in UK.
It found that, on average, Brits download two apps a month, but one in five are deleted after just one use.
Twenty six percent of respondents said they had deleted an app on the same day they got it.
When asked why, the most common reasons given were that the app was not relevant, did not help the user or was no longer needed.
Over the course of their lives, the average UK adult will download 1,512 apps but just 29 percent of the population is willing to pay.
Social media (54 percent) and banking/finance (44 percent) are the most useful apps, according to women, while 45 percent of men chose sport apps.
Scott Curtis, who leads Publicis Media’s mobile team in the UK, said: “Apps have only been around for a relatively short time but they have absolutely transformed the way we live our lives.
“And, it’s staggering to think how many the average person will download in their lifetime.
“However, our research has also highlighted that many don’t stand the test of time, with a quarter of apps deleted on the day of download.
“Any brand or company looking to develop an app must understand that launching it is only the beginning of the journey – apps must be engaging, useful and at all times relevant or face becoming quickly obsolete.”
