About Detox
Detox is an iOS app that blocks or limits any app for people who want to disconnect from their phone, with a different tool for each screen habit instead of one timer for everything.
Our bet is simple: people don't need to change who they are, their devices need to change how they behave. The phone is where we started, not where we stop. The goal is to make it possible to disconnect from every device and from the constant overstimulation that comes with them, which is why a Detox Chrome extension is now in review.
What Detox does
Different behaviours need different solutions. Each Detox feature targets one specific habit, and changes how your phone responds to it. Research backs this up: in one study, a grayscale screen cut daily screen time by 20 minutes but did not change how often people unlocked their phones, because checking is a separate habit (Dekker & Baumgartner, Mobile Media & Communication, 2024).
Auto Block: for when you open an app and lose an hour in it
Auto Block watches for continuous use, not total use. Quick checks stay free, but once you have been scrolling an app for longer than your limit, Detox locks it for a cooldown you choose. It interrupts the session at the moment it turns into doomscrolling.
What the research says: In a controlled field study, interrupting people once they stayed on an app past their limit cut daily use by more than 20%, though the effect faded once the intervention was removed. (Okeke et al., MobileHCI 2018)
Schedules: for when you open apps without thinking
Schedules block the apps you pick during the hours you pick, such as at night or during work. You can still take a break, but only after a short wait. That friction breaks the automatic reflex and gives you a moment to decide if you really want to open the app.
What the research says: Adding a short delay with an option to back out before opening an app reduced actual app openings by 57% over six weeks (a study co-authored by the founder of one sec, without a control group). In another study, students who stopped screens after 9 pm fell asleep earlier and slept longer. (Grüning et al., PNAS 2023; Perrault et al., SLEEP 2019)
App Limits: for when you want a daily budget
App Limits cap the total time you spend on an app each day. When the budget is used up, the app stays blocked until the next day, so the number you set becomes a real ceiling instead of a suggestion.
What the research says: In a randomized trial with about 2,000 adults, letting people set their own app limits cut time on the most tempting apps by 22 minutes a day (16%) over 12 weeks, and 78% kept their limits in place. (Allcott, Gentzkow & Song, American Economic Review 2022)
Block Now: for when you need to start something
Block Now locks your distracting apps immediately for a set time, with a Live Activity on the Lock Screen. It is the one-tap way to start a study session, a workout or a dinner without your phone.
What the research says: In a randomized trial, two weeks without mobile internet improved sustained attention, mental health and well-being, although only a quarter of participants complied fully. (Castelo et al., PNAS Nexus 2025)
Strict Mode and Urgent Unblock: for when you try to undo your own rules
Strict Mode locks a block's settings, and even uninstalling Detox, until the block ends. For real emergencies, Urgent Unblock releases everything, but only once every 24 hours.
What the research says: In a four-week field experiment, lockouts reduced use more than warnings did, but caused more frustration, which is why Detox keeps a limited emergency exit. (Kim et al., IMWUT 2019)
What makes Detox different
One tool per habit, not one timer for everything
Apple Screen Time and most blockers give you a daily time budget. Detox starts from the behaviour instead. Getting stuck, opening on autopilot and overspending time each get their own mechanism, so you only restrict what is actually a problem for you.
It steps in mid-session, not only at the door
Apps like one sec and Clearspace add a pause before an app opens. Detox's Auto Block acts during use: quick checks pass, and the lock only arrives once a session runs past your limit, which is when doomscrolling actually happens.
Rules that are hard to talk yourself out of
Apple Screen Time's limits have historically been dismissible with one tap unless you set a passcode. Detox's Strict Mode locks a block's settings and prevents uninstalling the app until the block ends, and the emergency exit is limited to once every 24 hours.
No hardware to buy or carry
Brick blocks apps with a $59 physical device you have to tap to unblock, with 5 emergency unblocks in total. Detox is software only: nothing to buy, carry or lose.
Built on published research
The founders co-authored a peer-reviewed study of Detox users in JMIR Formative Research (2026), with researchers from EPFL, HES-SO and Lausanne University Hospital (CHUV). What we learned there, that tools should adapt to what people actually do rather than what they say, shapes how every feature works.
Private by design
Detox uses Apple's Screen Time framework, which hides app identities from us. We can't see which apps you block or what you do in them.
Competitor details checked on their own websites and the US App Store in September 2026.
Who uses Detox
Detox is for iPhone users who want their phone to stop taking more time and attention than they choose to give it. Our users are mostly:
- Students and young professionals who need their phone for school or work, but not for hours of scrolling.
- People for whom Apple's built-in limits weren't enough: 57% of people installing Detox had already tried them (68% in France).
- People who feel anxious, tired or unfocused because of their phone: 37% say that's what made them look for a solution, and 29% were shocked by their screen-time total.
- Evening and bedtime scrollers: among Detox users, doomscrolling peaks between 9 and 10 pm.
- iPhone and iPad users in France, Switzerland, Belgium, Canada, the United States and beyond, in English, French, Spanish and Portuguese.
Figures come from anonymized, aggregated Detox data: onboarding answers from about 11,400 to 14,400 people (February to July 2026) and Auto Block logs (September 2026). See the full data and methodology
The team behind Detox
Detox started at EPFL in Lausanne, where Léo and Awen were master's students in computer science and cyber security. They first built it as a student project called Filos, which won the "Keep Pushing" award in EPFL's Changemakers programme in 2023, and launched it on the App Store in September 2023. Over two years of research they interviewed around 50 users and studied the data of more than 8,000, and published the results in a peer-reviewed journal in 2026.

Get help when you need it
Live chat is available from the Support page and inside the app: an AI assistant answers first, and our team takes over when needed. Step-by-step guides are in the Help Center at help.detox.so.
The research behind Detox
In "Restoring Engagement in Digital Self-Control Tools Using Nudge Reconfiguration Prompts" (JMIR Formative Research, 28 April 2026), we studied 252 Detox users who had switched their nudges off. About half of those prompted turned them back on, and those who did roughly doubled how often they engaged with the nudges, from 29.7% to 58.5% (+36.3 points compared with the control group). What people actually did in the app predicted who would come back better than what they said in surveys.
Disclosure: Awen Kidel Peña-Albert and Léo Litrico built the app studied. The co-authors from EPFL, HES-SO and Lausanne University Hospital reported no conflicts of interest.

Frequently asked questions
Is Detox free?
No. Detox is paid, with a free trial, so you can try every feature before you subscribe. Subscriptions are handled by Apple and can be cancelled at any time from your iPhone settings.
Is Detox available on Android?
Not yet. Detox runs on iPhone and iPad (iOS 16 or later). A Chrome extension for computers is in review.
How is Detox different from Apple Screen Time?
Screen Time mainly gives you daily time budgets, which have historically been easy to dismiss. Detox adds a limit on continuous use that interrupts long sessions, schedules with a waiting time before breaks, and a Strict Mode that stops you changing a block or uninstalling the app until it ends.
Can Detox see which apps I use?
No. Detox relies on Apple's Screen Time framework, which gives apps anonymous tokens instead of app names. We can't see which apps you block or what you do in them.
Who is behind Detox?
Detox was founded by Léo Litrico and Awen Kidel Peña-Albert, two computer science graduates from EPFL. The company, Detox SARL, is registered in France.
Is Detox based on science?
Yes. The founders published a peer-reviewed study of Detox users in JMIR Formative Research (2026), with researchers from EPFL, HES-SO and Lausanne University Hospital. We also draw on the wider research on friction, scheduling and self-control tools, which we summarize on our screen time statistics page.
