Spottable Review: The Deal-Scoring App for Facebook Marketplace

What Spottable is

Spottable is a Facebook Marketplace tool built by Harbourside Apps Pty Ltd, a company based in Neutral Bay, New South Wales. It was first released in March 2026 and reached version 1.5.0 in September 2026. Based on its AU App Store listing, checked 15 October 2026:

• What it does: searches Facebook Marketplace for listings matching your keywords, analyses each listing for price fairness and red flags, and — on paid plans — sends background alerts when new matching listings appear.
• Devices: iPhone and iPad on iOS 18 or later; also available on Mac with an Apple M1 chip or later and macOS 15 or later. Available in the Australian App Store and the US App Store.
• Facebook login: not required. Spottable’s listing states plainly: “Spottable does not need your Facebook password.”
• Rating: 2.6 out of 5 from 5 ratings on the AU App Store, 5 from 1 on the US App Store.
• Chrome extension: Harbourside Apps also publishes a separate Spottable extension for Chrome that scores a listing from 1 to 10 while you browse, without needing the iPhone app. It has 846 users and 4.3 from 6 ratings on the Chrome Web Store.

Spottable’s website, spottableapp.com, confirms the two separate products: the iPhone app for saved watches and alerts, and the Chrome extension for deal scoring in the browser. This review covers both, since they are sold by the same developer and serve the same buyer. We have not tested either; everything here comes from public listings checked on the day.

If you are comparing alert apps for the iPhone more broadly, the iPhone Marketplace alert app comparison covers Spottable alongside the other options. For the Chrome extension side, see the Chrome extension comparison.

Spottable pricing

Spottable is free to download. Paid tiers unlock saved watches, background alerts and a larger monthly AI allowance. Prices are from the AU App Store on 15 October 2026:

The number of saved watches per plan and the frequency of background alerts are not stated on the App Store listing, so neither can be compared directly. The listing mentions “Instant checks” as an optional add-on for “eligible plans”, but does not give a check interval. The AI credits figure (100/250/500 per month) comes from the app’s version history, not the current listing text; treat it as approximate.

There are also “Boosted Searches” add-ons, listed as 2, 5 or 7 per month at A$59.99, A$149.99 and A$229.99 respectively. The listing does not describe what a Boosted Search delivers over a regular watch.

For comparison, Outpost Alerts prices are in US dollars: $14.99 a month for one watchlist, $39 for five and $79 for ten, or 20% less billed yearly, with a 3-day trial on every plan and no free plan.

How Spottable scores a listing

The deal-scoring feature is what makes Spottable stand out from other Marketplace alert tools. It applies to both the iPhone app and the Chrome extension, though the two rate listings on different scales.

In the iPhone app, when you open a listing, Spottable runs an AI analysis that compares the asking price with local market context, highlights missing details or possible red flags, and helps you decide whether to message the seller or move on. The AU App Store listing describes it as providing deal summaries; it does not publish the exact scoring scale the app uses.

The Chrome extension is more explicit about its output. Open any Marketplace listing and click “Analyse with Spottable”; the extension returns:

• A Deal Score from 1 to 10
• A verdict: Great Deal, Fair Price, Overpriced or Avoid
• A suggested fair price and a live market price range
• A condition assessment with notes
• Red flag warnings for signs of scams, misleading descriptions or manipulated photos
• AI-written messages you can send to the seller in one click

The Chrome extension also has a batch mode: multi-select up to 20 listings from a search results page and see deal scores overlaid on the grid, so you can compare several at once without opening each one. This is the most distinctive feature of the Spottable ecosystem, and nothing in the current guide to Facebook Marketplace deal finders offers quite the same thing from the browser.

This kind of valuation tool answers the question “is this listing priced fairly?” rather than “is this listing available?”. Those are different problems, and it matters to understand which one you are trying to solve. An overpriced item you saw quickly is still overpriced; a fair deal you saw an hour after it went up may already be pending.

Saved watches and background alerts

Paid Spottable plans keep a saved watch running in the background and notify you when new listings match. The App Store listing describes this feature honestly but briefly: it does not state how many saved watches each plan allows, and it does not give a check interval.

The free plan gives no background alerts. The paid plans unlock them, with the option to add “Instant checks” to “eligible plans” for a higher priority search. What “instant” means in practice — a specific number of minutes — is not published.

This matters because the most useful comparison between alert tools is check speed, and it cannot be made here. A tool that does not publish its check frequency cannot be assessed on it; DealFlip AI is one of the few valuation tools that lists an interval for every paid plan, as our DealFlip AI review sets out. You would need to set up a paid plan and time the alerts yourself to know what you are getting.

The AI analyses count against a monthly allowance. The free plan gives 3 per day. The paid plans give 100 to 500 per month, which is enough for regular use; at 22 working days that works out to 4-23 analyses per day across the plans.

If you want to understand what frequency matters when buying on Marketplace, the guide to seeing the newest listings explains why the gap between a listing going up and your alert arriving is the whole game.

Why check speed is the harder problem

Deal scoring and alerts are both useful, but they fail differently. A poor deal score just costs you a moment. An alert that arrives late costs you the item.

Here is what happens when a seller lists a genuinely well-priced item on Facebook Marketplace. They want it gone quickly, so they price it below the going rate. Several buyers are watching that category. The listing collects messages within the first few minutes. The seller replies to the first person who can collect, marks it pending, and the item is gone. If your alert arrives thirty minutes later, you are seeing the history of something already sold.

This is not a rare edge case. It is the normal outcome for anything desirable. The people who move first do not win because they are more persistent or better negotiators — they win because they were there. That is the whole point of an alert tool, and it is why check speed is the number a buyer most needs to know before they pay for a plan.

Spottable’s listing does not give that number. The deal scoring and the AI analysis are genuinely novel features; the alert speed is the one that decides whether you get the item.

The best way to use both kinds of tool is to be alerted first, then score the deal to decide whether to message. That sequence makes sense even with separate tools: a fast alert from one app, a quick score from the Chrome extension while you are reading the listing. Using them in the wrong order — finding a good deal and then waiting for someone else to alert you to it — is not a strategy that works on Marketplace.

Where Outpost Alerts fits

Outpost Alerts is an Australian-built service that watches Facebook Marketplace for new listings matching your keywords and sends them to an iPhone app, a web dashboard or Discord. It searches from its own servers in the cloud, so it does not need your Facebook login and does not require your browser to be open. Here is how the two compare:

From each vendor’s own pages, checked 15 October 2026. Outpost prices are in USD from its pricing page; Spottable prices are in AUD from the AU App Store.

The case for Outpost rests on three things. First, published check speed: your fastest watchlist is checked every minute on Pro, every 3 minutes on Standard and every 30 minutes on Basic, with the other watchlists running slower (3 minutes or more on Pro, 5 minutes or more on Standard). You know exactly what you are paying for. Second, measured relevance filtering: across 30,777 keyword-matching listings, Outpost discarded 38.6% as not the item searched for — 18,890 kept against 11,887 rejected. That means a search for “road bike” does not fill your feed with helmets, racks, kids’ bikes and wanted posts. Third, control and delivery: include and exclude words, a price range, and one location with a 5–500 km radius per watchlist, delivered as push notifications in the iPhone app, on a web dashboard or to a Discord channel.

If you want to use Outpost’s alerts for the speed and Spottable’s Chrome extension for deal scoring before you message, they work well together — they do not overlap.

What Outpost does not do is worth saying plainly. It has no free plan; the trial is 3 days. It does not score or analyse individual listings — relevance filtering is not the same as valuation, and Outpost will not tell you whether a price is fair. It watches Facebook Marketplace only. There is no Android app, though Android users can use the web dashboard.

For the widest view across all alert apps, see the alert apps compared on speed and price and the free Marketplace alert options. The guide to excluding words from Marketplace results shows how to build the exclude lists that make a broad search stay relevant.

The verdict

Spottable is an Australian app with a genuine free tier and a deal-scoring feature that nothing else on the market quite matches in the same package. The Chrome extension’s 1-10 scoring with batch analysis is a useful way to compare several listings at once. It is a well-designed tool from an Australian developer and it does not need your Facebook password.

The weakness is transparency. The App Store listing does not tell you how frequently the background alerts run. You can judge deal quality before you message, but you cannot judge whether the alert will reach you in time to matter.

For most Facebook Marketplace buyers, Outpost Alerts is the better choice for alerts: it publishes its check frequency, checks your fastest watchlist every minute, filters out irrelevant keyword matches, and gives you control over include words, exclude words, price range and radius. If the deal-scoring side also appeals, the Spottable Chrome extension works alongside Outpost rather than instead of it.

Whichever you try, test it on the searches you actually care about and note when the alert arrives against the listing’s posted time. For ideas on what to watch, the ready-made watchlist ideas give keywords, exclude words and price ceilings by category.
