No social, no leaderboards, no streaks

Context

Every prep app on the market in 2026 has social mechanics. Streaks. Leaderboards. "Friends practising near you." Notifications nudging you back. The mechanics work — they reliably lift daily-active-users. They also reliably make the product feel like a casino.

Celer's target user has 6–10 weeks to land a senior role. They do not need engagement. They need a clean signal of where they stand.

Decision

No social. No leaderboards. No streaks. No daily-nudge notifications. No "users with similar profiles are working on…". No badges. No XP. No fire emoji.

The product surface is the candidate, the tags, and the question they have in front of them right now.

Consequences

Lower DAU. Measurably. Probably 30–50% lower than a comparable app that did ship these mechanics. We accept that.

Lower churn after success. When a candidate lands the role, they should stop using Celer. That's the desired end state. Engagement-optimised apps fight this; Celer welcomes it.

Defensible position. A senior candidate compares Celer to an alternative and immediately reads the difference. The competitors look noisy. Celer looks like a tool. That distinction is what we sell.

Marketing copy that writes itself. "Senior candidates don't need more questions; they need a system" is the headline of the homepage. It only works if the product backs it up. Adding streaks would make every page of the marketing site dishonest.

Cost we're not absorbing

We're not absorbing the cost of being addictive. The energy that would go into push-notification copywriting, streak-recovery flows, and milestone celebrations goes into the practice engine instead.

When this becomes the wrong answer

If candidates routinely abandon Celer mid-prep because there's nothing pulling them back, we revisit. The signal we'd watch is "completion rate of multi-week prep plans". As of writing, that signal is fine. If it ever isn't, the answer is better recommendations, not streaks.
