People are growing weary of the constant stream of alerts on their phones and struggling to make it through a meal without checking their screens. They’re worried about being tracked. They have tech neck, and it hurts.

As digital culture moves out of its honeymoon phase, a backlash industry has sprung up, with coaches to help people break up with their devices, digital detox camps and tech diets. Mindful of the new mindfulness, Apple and Google have incorporated screen time monitors into their products.

A new study that tracked how 2,444 Americans used their mobile devices over 14 months backs up the general sense of tech fatigue. It found that 64 percent of participants scaled back their app use during the time they were tracked, spending four hours a day on apps, down from five at the start of the study.

A retreat from mobile devices could have “large implications for marketers and for the digital business models that rely on capturing attention,” wrote Renee Cassard, the chief audience officer at the media agency Hearts & Science, which commissioned the report.
