Gamification isn't badges sprinkled on top of a product. It's a feedback loop: a user acts, the action is recognised, that recognition pulls them back to act again. Done well, it's the difference between an app people try and an app people keep. Here's the loop — and the six primitives Streakline uses to build it.
An event is any meaningful thing a user does — finishing a lesson, logging a workout, inviting a friend. Your app sends these to Streakline with one call. Events are the immutable record of what happened; everything else is derived from them.
track("lesson.completed", { userId })
Each event type has a multiplier. Optional bonuses stack on top — a streak bonus, a first-action-of-the-day bonus, a combo bonus for momentum. The result is a score that reflects not just what users did, but how consistently and how well.
score = base × multiplier × (1 + bonuses)
Accumulated score moves a user up a level curve. Levels give long-horizon motivation — a visible track that always has a next rung. The curve is tuneable, so early levels feel quick and later ones feel earned.
Streaks reward showing up repeatedly. Streakline tracks daily, weekly, or custom cadences — and hands out freeze tokens so a single missed day doesn't wipe out weeks of momentum. Streaks are the single strongest retention lever in the toolkit.

Achievements are permanent recognition for reaching a milestone. Each carries a rarity tier, so a diamond badge actually means something. They give users collectible goals beyond the daily grind.
Leaderboards turn individual progress into friendly competition — daily, weekly, or all-time, ranked by individual or team. Real-time ranking keeps them honest, and scoping keeps them motivating instead of demoralizing.
Most platforms treat scoring as a setting you edit in place — and if you change a multiplier, every historical score silently shifts with no record of why. Streakline treats scoring as versioned data over an immutable event log.
Per-event cooldowns stop rapid-fire abuse — the same action can't be farmed for points in a tight window.
Each event type has a cap, and there's a global daily ceiling, so no single user can run away with the board.
Every event can carry an idempotency key, so retries and double-taps never double-count.
You just read the model. Streakline's agent reads your codebase and assembles it — mapped to your real product, ready to review.
