Features and specs

What each product offers, as listed by its team.

FindersKeepers.app 5 features
JST
JavaScript Tutorial 5 features
  • Hourly Alerts
    We re-check every saved search and watched listing every hour, then email or push you the moment a price drops or a new match shows up. eBay batches its own alerts on its schedule.
  • Deal Scoring
    See how a listing's price stacks up against similar active listings. Anything 20% or more below the average asking price gets flagged as a hot deal, 10 to 20% below as a good price.
  • Price History
    Watch an item and we record its price every six hours, so you can tell whether it is drifting down or holding firm. eBay listing pages show you no price chart at all.
  • Auction End Alerts
    Get a heads up when a watched auction enters its final 24 hours, plus optional countdown alerts at 1 hour, 30, 15, and 5 minutes that you set per item.
  • Image Search
    Snap or upload a photo and we find matching eBay listings, so you can hunt for something you can picture but cannot name.
  • Accessible Learning Format
    Delivered as a mobile/web app, allowing learners to study JavaScript concepts on-the-go from their smartphones without needing a desktop setup.
  • Free or Low-Cost Access
    Apps built on platforms like AppCreator24 are often free or inexpensive, making it easy for beginners to start learning JavaScript without financial commitment.
  • Beginner-Friendly Structure
    Likely organized into simple, bite-sized lessons or modules that help newcomers grasp basic JavaScript syntax and concepts step-by-step.
  • Convenient for Quick Reference
    Useful as a quick-reference tool for reviewing JavaScript basics such as variables, functions, and loops without needing to search through lengthy documentation.
  • No Installation of Development Tools Required
    Since it's app-based, users can review tutorial content without setting up a full coding environment, which is helpful for on-the-go review.

Possible disadvantages

  • Limited Interactivity
    Unlike dedicated coding platforms (e.g., Codecademy or freeCodeCamp), apps built with generic app builders like AppCreator24 often lack live code editors or interactive exercises for hands-on practice.
  • Potentially Outdated or Shallow Content
    Tutorials hosted on third-party app-building platforms may not be regularly updated to reflect modern JavaScript (ES6+) features or best practices.
  • No Community or Support System
    Lacks the peer support, forums, or instructor access found in established learning platforms, making it harder to get help when stuck.
  • Unverified Credibility of Content Creator
    Since this is a user-generated app rather than content from a recognized educational institution or established tutorial site, the accuracy and depth of the material may be inconsistent or unverified.
  • Limited Scalability for Advanced Topics
    Such apps are typically designed for basic tutorials and may not adequately cover advanced JavaScript topics like asynchronous programming, closures, or frameworks (React, Node.js, etc.).

Questions & Answers

As answered by people managing FindersKeepers.app and JavaScript Tutorial.

What makes your product unique?

FindersKeepers.app's answer

Two things eBay does not give you, in one place.

Alerts run on a fixed hourly schedule instead of eBay's own batching, so you hear about a price drop or a new match while it is still actionable. And every item you watch gets a price history, recorded every six hours from the day you add it, which eBay listing pages do not offer at all.

On top of that, listings are scored against similar active listings in the same search, so you see whether an asking price is actually good instead of just seeing a number. Twenty percent or more below the average is flagged as a hot deal.

All of it is free, with no paid tier, and you can search eBay through FindersKeepers without an account or an eBay login.

Why should a person choose your product over its competitors?

FindersKeepers.app's answer

Because it covers the whole job for free, and it tells you when another tool is the better pick.

Most eBay tools do one piece well. WatchCount reads real sold data. Madealert pushes alerts within seconds of a listing appearing. eBay's own saved searches are already built into the site you are shopping on. FindersKeepers puts hourly alerts, price history, deal scoring, auction countdowns, saved searches, seller watchlists, image search, and collection tracking together at no cost, on US and international eBay marketplaces.

We also publish comparison pages against nine other tools, written in-house, including the parts where the other tool wins. Madealert beats our hourly check on speed and the page says so. That is the same standard the blog holds: every factual claim about how eBay works links to the eBay help page it came from.

How would you describe the primary audience of your product?

FindersKeepers.app's answer

Collectors and bargain hunters who shop eBay regularly. Trading cards, watches, coins, video games, vinyl, retired LEGO sets, Funko Pops, vintage clothing, ex-corporate hardware.

These are buyers, not sellers. They already have a mental want list and a rough sense of what a fair price looks like, and they are tired of refreshing the same search, missing an auction by twenty minutes, or finding out later that the listing they passed on was actually underpriced.

The common thread is caring about paying the right price for one specific thing, rather than browsing deals in general.

Which are the primary technologies used for building your product?

FindersKeepers.app's answer

Next.js on the App Router, with React and Tailwind on the front end, deployed on Vercel.

Listing and pricing data comes from eBay's APIs. A scheduled job re-checks every saved search and watched item on a fixed hourly cadence, records watched-item prices every six hours, and computes deal scores against the comparable active listings in the same search. Alerts go out over email and web push.
