What this app is. What it isn’t. What you could build.

One-liner

A membership-required shopping app for Costco members that enables online ordering, digital membership access, and store event updates, but suffers from poor usability and limited guest functionality.

Strengths

Provides full digital membership integration for in-store use (review: 'デジタル会員証が便利で、スマホで確認できる')
Offers real-time order tracking and purchase history (review: '注文履歴が見られて安心')
Delivers exclusive member discounts and promotions (review: '会員限定の割引がアプリで見られる')
Centralizes warehouse event information and online shopping in one place
Supports new membership signups and renewals directly within the app

Weaknesses

Low overall rating (2.04) with frequent complaints about poor UX and crashes (review: '頻繁に落ちるし、操作がめんどくさい')
Limited guest functionality frustrates non-members (review: 'ゲストでも使える機能が少なすぎて意味がない')
Slow performance and outdated UI (review: 'デザインが古くて重い')
Poor navigation and confusing menu structure (review: 'どこにあるか分からず、探すのが大変')
Frequent login issues and session timeouts (review: 'ログインしてすぐ切れる')

Opportunities

Build a lightweight, guest-friendly version focused on product search and price comparisons without requiring login
Create a minimalist 'Costco Deals Tracker' that aggregates discount alerts and event info via web scraping or RSS feeds
Develop a companion app for members that enhances order tracking with push notifications and delivery ETA estimates
Design a visual product catalog with high-quality images and user reviews to improve discovery
Offer offline access to member-only deals and shopping lists for users with spotty connectivity
