FAQ
Good questions, straight answers.
Everything people usually ask about SnagSonar.
What is SnagSonar?
SnagSonar is a deal-alert app for people who flip and resell. You set up searches for what you buy, and SnagSonar watches new listings around you and alerts you the moment a match (or an unusually good deal) appears.
Which marketplaces does it watch?
Facebook Marketplace today. OfferUp and Craigslist are next on the list.
How fast are the alerts?
Each search can check as often as every 15 seconds. Facebook reviews new posts for a few minutes before anyone can see them, so an alert that says “posted 7 minutes ago” usually means you're among the very first people to see it.
How do I get notifications on my phone?
SnagSonar works in your phone's browser and can be added to your Home Screen like an app. Alerts arrive as push notifications through the free ntfy app. Setup takes about a minute in Settings → Notifications.
How does it know what's a good deal?
It compares each listing with similar items listed near you and shows the typical price, how far under it the listing is, and your estimated profit after fees and shipping. It's an estimate, so always take a look before you buy.
How much does it cost?
Your first 7 days are free, with full access. After that, plans start at $4.99 a week or $14.99 a month. Cancel anytime; you keep access until the end of what you paid for.
Is SnagSonar part of Facebook?
No. SnagSonar is independent and isn't affiliated with Facebook, Meta or any marketplace. Every purchase is between you and the seller.
How many searches can I have?
Each plan includes a set number of saved searches (10 on our standard plans). Each one can have its own keywords, price range, area, category, check speed and alert style.
What categories are supported?
Cars and trucks, electronics, furniture, tools, bicycles, appliances, household, garden, boats, trailers and antiques, all on Facebook Marketplace.
Can it search for cars?
Yes. Car searches add year, mileage and price limits, and can skip salvage and rebuilt titles.
Can I pause my alerts?
Yes. Pause for an hour, a few hours, until morning or until you resume, from the home screen or Settings. Your searches stay saved.
What does SnagSonar do with my data?
Only what it needs to run your searches and send alerts. We don't sell data or show ads. The Privacy Policy has the details.
How do I delete my account?
Settings → Login & security → Delete account. Everything is removed right away.
Do I need to download an app?
No. SnagSonar runs in your browser and can be added to your Home Screen so it opens full-screen like an app, on iPhone and Android. Here's how. Phone alerts come through the free ntfy app.
How is this different from Facebook's own saved-search alerts?
Facebook's alerts arrive late and only tell you something matched. SnagSonar checks as often as every 15 seconds, filters out junk, shows you the typical local price and estimated profit, and tells you when a seller drops a price. It's built for people who buy to resell.
Does SnagSonar message sellers for me?
No. It gets you there first and gives you one-tap message templates, but you send the message yourself from Facebook. Automated messaging gets accounts banned, and sellers can tell.
I forgot my password
Tap “Forgot password?” on the log-in screen. If your account has an email, we'll send a reset link. Otherwise log in with your access code and set a new password in Settings.
How do I find underpriced items on Facebook Marketplace?
Know the going rate for a few categories, watch new listings the moment they appear, and compare each asking price against what similar items near you list for. SnagSonar does the watching and the comparing for you, and our guide to finding underpriced items walks through the whole method.
Can I get Facebook Marketplace alerts on my iPhone?
Yes. SnagSonar sends real push notifications to iPhone and Android through the free ntfy app, with the price, distance and typical local price in the alert. Add SnagSonar to your Home Screen and it opens full-screen like an app — here's how.
How fast are the alerts?
SnagSonar checks your searches as often as every 15 seconds, around the clock, so the gap between a listing going public and your phone buzzing is usually seconds. Facebook itself holds each new listing for a few minutes of review first, which is why fresh alerts often say “posted 7 minutes ago” — you're still one of the first to see it.
Does SnagSonar work for flipping cars?
Yes — car searches get year, mileage and price filters, salvage and rebuilt titles can be skipped automatically, and when a listing includes a VIN you get a free decode with open-recall checks. See SnagSonar for dealers.
Can I watch more than one city or area?
Yes. Every search has its own ZIP code and radius (10 to 100 miles), so one search can watch Seattle while another watches Tacoma.
Will SnagSonar get my Facebook account banned?
No — SnagSonar never logs into your Facebook account, never asks for your Facebook password, and never messages anyone for you. It watches public listings and alerts you; you open the listing and message the seller yourself, like any other buyer.
