Questions & Answers

As answered by people managing Underpriced.App and Eclipse.

What makes your product unique?

Underpriced.App's answer

Underpriced.App is built for one thing: helping you spot underpriced items fast and confidently. Instead of guessing from a single listing photo or a seller’s description, it focuses on market-backed signals (comps, pricing patterns, and profit context) so you can decide “buy / pass / offer” in seconds. It’s designed around real reseller workflows—Facebook Marketplace and local deals, quick checks on the go, and repeatable decision-making—without turning it into a bloated spreadsheet app.

Why should a person choose your product over its competitors?

Underpriced.App's answer

Most alternatives either (1) give generic “estimated value” numbers with little context, or (2) require a lot of manual searching and interpretation. Underpriced.App is streamlined for speed and clarity: it’s meant to reduce hesitation and prevent overpaying by surfacing the right signals at the right time, then turning those into an actionable recommendation. It’s also built to scale with you—from casual thrifters doing occasional flips to serious resellers who need consistent, repeatable results.

How would you describe the primary audience of your product?

Underpriced.App's answer

Underpriced.App is for deal-hunters and resellers who want to make smarter buying decisions: people who browse Facebook Marketplace, thrift stores, garage sales, liquidation, and retail arbitrage opportunities and need a quick way to validate price and profit potential. The core audience is practical and time-constrained—buyers who don’t want to do 10 tabs of research for every item, but still want decisions backed by real market behavior.

What's the story behind your product?

Underpriced.App's answer

Underpriced.App comes from a simple pain point: flipping and deal-finding isn’t hard because there are no deals—it’s hard because it’s easy to overpay, miss red flags, or waste time doing research that doesn’t translate into a clear decision. The app was created to make that moment of uncertainty disappear by turning “Is this actually a deal?” into a quick, repeatable process grounded in comps and market reality.

Which are the primary technologies used for building your product?

Underpriced.App's answer

Underpriced.App is a modern web-first product with mobile support: React + Vite for the UI, Tailwind CSS for styling, Capacitor for mobile app packaging, Firebase (Auth + Firestore) for user/accounts and data, and Vercel serverless functions for API endpoints and integrations (like billing and webhooks). It’s optimized for fast iteration and reliable deployment while keeping performance strong.

Who are some of the biggest customers of your product?

Underpriced.App's answer

Full-time resellers running consistent daily sourcing Part-time flippers who source on weekends and evenings Facebook Marketplace buyers trying to avoid overpaying Thrift and garage-sale shoppers who want quick price validation Retail arbitrage beginners learning what’s actually profitable Small resale operations scaling from “side hustle” to steady revenue
