What happened to Opal Buddies — and why social features disappear

Opal Buddies was released in April 2022 and deprecated five months later for lack of usage. That is a useful warning for anyone building social screen-time software — but not the warning people usually take from it.

The lesson is not that people refuse help from friends. It is that turning a friend into an alarm recipient is a thin social product.

What happened to Opal Buddies?

The receipt is still public. Opal’s Introducing Opal Buddies page says the feature was released in April 2022 and deprecated in September 2022 “due to lack of usage”.

Its core mechanic was simple: when you went off track in an app, Opal would message your buddy. The user acted; the buddy received a report.

That arrangement creates several problems at once:

• The buddy has no shared goal inside the product.
• The message arrives after the behaviour, when it is too late to change the decision.
• The only product-defined role is to notice a lapse.
• Opening the app offers the buddy no meaningful action beyond judgment or reassurance.

Calling that “accountability” does not give the relationship a job.

Opal Buddies was not the only one

The same shape has died more than once. In February 2019, the makers of an iPhone app called Goldilocks posted it to r/getdisciplined as “Use your smartphone less, with the support of friends”. It tracked pickups and screen time and let you add friends or accountability partners. The post did well — roughly 330 upvotes.

Read the replies and you can watch the product hit two walls before it ever hit retention. The most upvoted comment was “Would love something like this for Android.” The next-loudest responses were about the price of admission: “Don’t really like that you have to share location all the time,” and, from another commenter, “You lost me at Continuous location tracking.” The developer answered candidly that iOS then limited how apps could reach the data they wanted.

When we looked Goldilocks up in the US App Store on 9 September 2026, it returned no result.

We cannot say why it was withdrawn, and leaving a storefront proves nothing on its own. But set the two cases side by side and the failure is not that people dislike doing this with friends. Opal Buddies asked the friend for attention nobody kept spending. Goldilocks asked the user for data nobody wanted to hand over. Both costs are recurring, and both are paid before any benefit arrives.

There is a third wall, visible in a January 2026 r/AppIdeas thread proposing almost exactly this feature again. A commenter who had tried it replied: “Ditch it bro, we have tested it. Sounds nice in theory, but in practice it’s just adding guilt, and that’s making the problem worse and not better.” Attention, data, guilt — a social screen-time feature has to survive all three, and a notification aimed at a spectator survives none of them.

The category keeps building spectators

Other social mechanics improve one part of the design without changing its basic shape. A leaderboard gives both people something to do, but couples two separate budgets through competition. An approval app makes the partner active, but casts one person as the asker and the other as gatekeeper. Roots says, “Think of Roots as your friendly accountability partner,” making the software — not another person — the partner.

The folk workaround is to hand someone else an Apple Screen Time passcode. It can add friction, but it also gives one adult a control credential over another.

Each model bolts a social signal onto what is still fundamentally a solo system: my limit, my lapse, your reaction.

Support is not the same as a shared stake

A 2021 randomised clinical trial in JAMA Network Open makes the distinction unusually clear. Veterans receiving gamification plus social support increased their daily steps by 433 compared with control, a non-significant result. Add a loss-framed financial stake and the difference was 1,224 steps a day, statistically significant during the intervention. Neither effect persisted after the intervention ended.

The study was about physical activity, not phone use, and a financial incentive is not a shared screen-time pool. It does show why “someone knows” and “something we both value is affected” are different mechanisms.

The same pattern appears in research on the Köhler effect. In one exercise experiment, participants persisted for 10.6 minutes alone, 19.77 minutes beside a partner, and 21.89 minutes when the team’s result depended on the first person to stop. A meta-analysis of 17 studies found a moderate motivation gain and identified task structure as an important moderator.

Presence helped. Interdependence helped more.

A social feature needs a shared object

Our design rule is this: both people need a meaningful relationship to the same object.

In Scrollmates, exactly 2 people share one pool of minutes. Either can claim time without asking permission, but the claim is visible and reduces what remains for both. Neither becomes the other’s administrator. Both choose to join, both see the same kind of information, and either can leave.

That does not guarantee a good outcome. A shared stake also raises the cost of a poor pairing. If one person never wanted the goal, the pool turns disagreement into a number; it does not resolve the disagreement. Scrollmates is an accountability aid, not a hard lock, and we do not yet have efficacy data showing that its model reduces use.

The narrow lesson from five months

Opal Buddies gives us one clean result: a one-way notification feature attracted too little use for Opal to keep it.

That is evidence against the snitch notification. It is not evidence against friendship, cooperation or every two-person design. The more useful question is not “Did social screen time fail?” It is “Did both people have anything to do together?”

Frequently asked questions

When was Opal Buddies discontinued?

Opal says it was deprecated in September 2022, five months after its April release.

Was Opal Buddies mutual?

Opal’s published description centres on notifying a buddy when the user went off track. It does not describe a jointly held limit.

What makes accountability mutual?

Both people opt in, face comparable visibility, can leave, and have something at stake in the same outcome.

Build teammates, not spectators

A social feature is not social merely because a second phone receives a push notification. It becomes social when two people can act as teammates around a goal they genuinely share.
