Track Real Karachi Restaurant Prices Across Foodpanda & Official Websites.
Every night at 03:00 PKT, DishMetric PK audits official Karachi storefronts against aggregator listings—exposing hidden delivery markups, fake promo discounts, and true food inflation since Launch Day.
Cross-Channel Spreads & Confirmed Price Moves
Ranked by Foodpanda base markup over official restaurant websites, alongside verified 2-run price revisions.
Karachi 9-Cohort Inflation & Spread Index
Equal-weighted basket index normalized to Launch Day = 100.0 across all 302 tracked Karachi branches.
Data Integrity & Index Methodology
A detected menu price change is quarantined on Night 1 and only enters the public ledger once confirmed across two consecutive 24-hour runs—eliminating POS glitches and momentary cache errors.
Any single-night price jump or drop exceeding ±60% is automatically held for manual verification so currency typos or out-of-stock placeholder prices never corrupt historical cohort indices.
Spread (%) = ((Foodpanda Base − Website Base) / Website Base) × 100
