Replace a rigid, manual challenge with an always-on program that ingests body-scanner data and issues instant rewards tied to verified progress.

• POS opt-in and Shopify companion flows so customers can join, track progress, and see milestones.
• Body-scanner ingestion with normalized, de-duplicated events mapped to each participant’s timeline.
• Real-time milestone detection that issues instant Klaviyo SMS rewards and surfaces the reward in POS.
• Support tooling and audit trails for troubleshooting and safe manual corrections.

• ~140k device scans processed; ~21k challenge enrollments.
• ~17k lbs of verified body-composition improvement (muscle gain or fat loss).
• Time-to-reward reduced from days (manual weekly batch tabulation) to seconds at milestone events.
• Replaced nationwide “weigh-in / weigh-out” batch ops with continuous, device-verified automation.

• Group challenges: leader join codes (shown in POS + Shopify), with leaderboards and group stats in both surfaces.
• Ops dashboard: queues and milestones (pending/sent/canceled) with safe replay.
