Digital Self-Control Apps (DSCAs) are tools - usually browser extensions or mobile apps - that individuals voluntarily adopt to help them reduce time spent on social media and other platforms they consider distractions. DSCAs use a variety of strategies to help users reduce time on distracting platforms, including setting time limits, reminding users of their goals, adding friction, self-tracking and doling out rewards or punishments.

While these apps vary in the mechanisms they use, they all aim to reduce time spent on platforms that users specify are distracting.

Roffarello and Russis (2023) conducted a meta-analysis of seven field experiments which each tested whether DSCAs were effective in reducing time spent on platforms that users identify as distracting. (Note: a meta-analysis uses statistical techniques to combine the data from multiple studies and estimate an overall effect as if they were one study.) The authors found a statistically significant effect, showing the apps overall reduced time spent by about 0.5 standard deviations, which social scientists generally consider a "moderate effect". 

There are several reasons why the meta-study above - on its own - does not make us confident thats all - or even many - DSCAs are effective. One reason, mentioned by the authors, is that most of the studies only looked at short term effects (~ 21 days); it is possible that any effect would wear off over time as users lose their initial motivation. Another concern is that most of the studies use a "within-subjects" design (i.e. the study flips the apps on and off for each user) which can distort the apps’ effectiveness. Equally importantly, the seven studies included in the meta-analysis test apps that take different approaches and likely are of varying quality; which is to say it would be hard to conclude that any given DSCA is effective. A final limitation to many of the studies is that they do not inspect how users may be compensating for less time spent on specific apps by spending time on other potentially distracting apps, which Goll & Huffstadt (2024) finds is the case in a study with a small sample of users. Two additional studies, Kovacs et al., 2019 and Gruning et al, 2023, which were not included in the meta-analysis above, had similar findings and limitations. 

Two subsequent studies, however, do give us confidence that at least some DSCA interventions are effective and that effects do not fade over time. The Danish Competition and Consumer Authority (2025) conducted a field experiment in which teens were recruited and paid to use a DSCA mobile app (one.sec) and assigned to use one of three interventions: one that forced a six second pause and breathing prompt before they entered any social media app; one that required they specify how much time they planned to spend on a social media app before entering (and subsequently required them to re-specify when that time was up); and, finally, a prompt that asked them to reflect on why they wanted to use a social media app (but only asked them one out of five times). Over a three week period, researchers saw a dramatic ~33% drop in social media usage for teens in the breathing and planning conditions (from an average of three down to two hours a day). While that study was still relatively short term, a second observational study (Halliburton et al., 2024) that draws on 300+ days of data from one.sec users suggests that the effectiveness of DSCA interventions endures.

Overall, we see convincing evidence that Digital Self-Control Apps can be effective in reducing time on social media apps, with two specific interventions - a forced six second breathing pause and a requirement to specify the time for planned use - demonstrating particular promise as effective approaches. 

Platforms are becoming increasingly proficient in their ability to capture and keep users' attention, which can have an adverse effect on individuals' sense of satisfaction and wellbeing. Digital Self-Control Apps give individuals who are aware of the potential detrimental effects of social media and other engagement platforms a promising way to exercise agency and improve their wellbeing. 

In general DSCAs are apps that browsers or mobile operating systems would offer as a tool to help users have a more fulfilling online experience. We assume for the most part that social media platforms that aim to maximize engagement would not offer these tools; however, platforms that want to offer a more healthful experience might also adopt these tools so users can, for example, "scroll responsibly". Indeed, we have seen platforms adopt versions of the interventions discussed above. See, Instagram’s time limit feature, a similar time management feature on Threads, and a breathing pause on Instagram.)

Digital Self-Control Apps may also only be effective for users who choose to use them, although Instagram reports that its breathing pause intervention - which it sets for all teens at night - is effective at reducing their late night use. 

It is likewise likely that only a subset of the strategies are effective in reducing time spent on distracting apps; for example, as suggested by Gruning et al (2023) and DCCA (2025), mere messages reminding users they may want to take a break or cuing users to reflect on their social media use could be ineffective. This observation is salient when examining any anti-addiction interventions platforms introduce claiming that they are aiming to reduce addiction.
