Waypack: Peer-to-Peer Parcel Delivery Mobile App
Connecting people who need to send items with travellers already heading along the same journey.
Waypack (com.app.carryoo) is an on-demand peer-to-peer parcel delivery platform engineered to connect senders with verified travellers heading along their delivery routes. By utilizing planned journeys and spare luggage space, Waypack offers a sustainable, cost-effective alternative to traditional couriers, complete with in-app price negotiations, escrow-backed card payments, traveler identity verification, and numeric delivery-code confirmations.
The Challenge
Traditional parcel delivery is frequently slow, inflexible, and costly when an item needs to reach someone along a particular route or within a specific timeframe. Simultaneously, travelers regularly make scheduled journeys with available luggage or vehicle space that goes unused. The primary product challenge was engineering a trusted, two-sided peer-to-peer ecosystem that overcomes mutual hesitation between strangers, shields private residential addresses, simplifies real-time price negotiations, and confirms parcel handovers securely without physical paperwork.
The Weblinx Solution
From adaptive Figma mobile and tablet design systems to cross-platform mobile engineering, Waypack connects senders and travellers seamlessly. Senders publish parcel requests with item specifications, pickup/destination guidelines, deadlines, and proposed budgets. Verified travelers heading along matching routes submit offers and negotiate delivery fees via in-app chat. To guarantee transaction safety, payments are held securely in escrow, addresses remain generalized until booking confirmation, and payouts unlock only upon verification of a 6-digit numeric delivery code at final handover.
