Server-side prize control
Every outcome is picked by a secure RNG on our server against your odds and inventory caps. The wheel animation only eases onto the slice that was already chosen — impossible to tamper with from the browser.

Profit-first spin-to-win for Shopify
The spin-to-win that proves it made you money 💰
Most wheel apps celebrate spins and signups. Profiter keeps a holdout control group and measures the real incremental profit per visitor — after discounts and shipping. Fair, server-side, and impossible to game.

Incremental profit, measured
Know exactly what the wheel added to your bottom line
Enter your margin and shipping cost once. Profiter compares shoppers who saw the wheel against a holdout who didn't, then reports profit per exposed visitor — the one number that answers "did this actually pay off?"
- Treatment vs. holdout, side by side
- 95% confidence intervals on every result
- Sample-ratio-mismatch guardrails catch broken tests
🖥️ Shopper clicks spin
→ 🔒 Server picks the slice
→ 🎡 Wheel eases onto it
The browser is only told which slice to land on — after the decision is made. Nothing to tamper with.

Incremental-profit dashboard
Enter your margin and shipping cost once. See profit per exposed visitor for shoppers who saw the wheel versus a holdout who didn't — the only number that tells you if the popup actually paid off.
Holdout A/B experiments
Deterministic, persistent bucketing keeps a true control group. Confidence intervals and sample-ratio-mismatch checks are baked in, so you only call a winner once the math agrees.
Auto-applied discounts
Winners get a single-use code created through Shopify Functions and applied straight through the cart — no one has to copy, paste, or remember anything at checkout.
Six themes, fully yours
Start from Seaside Fairground, Mint Boutique, Midnight Jackpot, Rose Atelier, Streetwear Drop or Winter Market — then tune colors, fonts, logo, launcher and victory effects to match your store.
Privacy-first by default
Consent is never pre-ticked, email is minimized and hashed, double opt-in is supported, and Shopify's GDPR webhooks perform real deletion and export. No dark patterns.
Integrations
Leads flow where you work
Sync every opt-in to your email and messaging stack, with consent and double opt-in status carried through.

Questions
Good to know
How is this different from every other spin-wheel app?
Most spin-wheel apps report spins and email signups and call it a day. Profiter keeps a holdout control group that never sees the wheel, then measures the difference in profit per visitor. You find out whether the popup actually made money after discounts and shipping — not just whether people played.
Can shoppers cheat the wheel or force a jackpot?
No. The winning slice is chosen by a cryptographically secure RNG on our server, against the odds and inventory limits you set. The browser is only told which slice to ease onto after the decision is made, so there's nothing to tamper with client-side.
Do customers have to copy a discount code?
Never. Each win creates a single-use discount through Shopify Functions and applies it through the cart automatically, so the offer is already waiting at checkout.
What counts toward my plan's pageviews?
Each time the popup is served to a visitor counts as one pageview. Free includes 1,000 per month, Growth 25,000, and Pro 150,000. You get clear warnings at 80% and 95% before anything is capped.
