Party Squasher Review
Party Squasher is a phone-counting sensor built to catch an unauthorized gathering before it becomes a noise complaint — hardware and a subscription, not another piece of guest-messaging software.
Pros
- One sensor is built to cover an entire property — house plus front and back yard — by counting nearby phones, instead of needing multiple room-by-room noise pucks
- Counts phones rather than listening with a microphone or watching with a camera, which the company positions as a more private, harder-to-fool alternative to audio-based noise sensors
- Hardwired to the router over Ethernet with no batteries to replace, and reports occupancy counts to the app multiple times a minute for real-time and historical viewing
- Calendar sync with Airbnb, HomeAway, and VRBO lets you cross-check an occupancy spike against who's actually booked, across multiple properties from one app
- Six-month money-back guarantee, plus volume pricing that steps down for portfolio operators — as low as $108–$132 per unit on renewal at 250–499 units
- 4.6 out of 5 on the Apple App Store, including a reviewer citing three years of continuous use — though the rating is built on only 8 reviews
Cons
- Purely an occupancy counter — it doesn't detect noise, smoke/vaping, or temperature, so it can't stand in for those sensor types if you want that coverage too
- Needs a wired Ethernet connection to your router, not just Wi-Fi — a real installation constraint some competing sensors skip
- The company's own site says it's "less suitable for townhouses, apartments, or condos (especially in multi-unit wood-framed buildings)" because the sensor struggles to separate a guest's phone from a neighbor's
- It's a recurring annual subscription tied to the hardware, not a one-time purchase — the sensor needs an active plan to keep reporting ($199/year renewal for Standard at 1–9 units, $252/year for Pro), so the cost never drops to zero
- Independent review coverage is thin — we found no G2 or Capterra listing for the product, and Amazon's customer-review page blocked automated access during our research, leaving only a small, 8-review Apple App Store page to cross-check
Party Squasher is not another guest-messaging or PMS tool — it's a physical sensor built to answer one narrow question: how many people are actually inside a short-term rental right now. The company, owned by BlueZoo, Inc., calls it "the first guest occupancy counter for homes," and instead of a microphone listening for noise, its roughly 2.3 x 2.3 x 0.9-inch sensor counts nearby mobile phones and reports the count to a companion app, aiming to flag an unauthorized gathering before it turns into a noise complaint, a damage claim, or a neighbor calling the police.
Pricing
Per Party Squasher's own pricing page, there are two tiers, both billed annually and both including the sensor hardware in the first-year price. Party Squasher Standard runs $249 in year one for 1–9 units, renewing at $199/year, and steps down to $119 first-year / $108 renewal at 250–499 units. Party Squasher Pro — which adds a web dashboard and API access on top of everything in Standard — runs $309 in year one for 1–9 units, renewing at $252/year, down to $149 first-year / $132 renewal at 250–499 units. The company backs both with a six-month money-back guarantee, and portfolio operators with 500+ units are directed to contact sales for further volume pricing. This is a recurring subscription tied to the hardware, not a one-time purchase — you keep paying the annual renewal to keep the sensor reporting.
Who it's for
Party Squasher is built for owners and managers of single-family short-term rental homes who want an early warning system for unauthorized parties — one sensor is meant to cover an entire house plus front and back yard. It syncs with Airbnb, HomeAway, and VRBO calendars so an occupancy spike can be checked against who's actually booked, and the Pro tier is built to scale up to portfolio managers running as many as 1,000 properties through API access. It's explicitly a weaker fit for attached housing: the company itself states the product is "less suitable for townhouses, apartments, or condos (especially in multi-unit wood-framed buildings)" because the sensor struggles to separate a guest's phone from a neighbor's through shared walls.
What we could verify
We could confirm the core mechanics, pricing, and stated limitations directly from Party Squasher's own site: the sensor connects to your router over a wired Ethernet connection rather than just Wi-Fi, runs on standard power with no batteries to replace, and is CE-, RoHS-, and FCC-certified. Independent review coverage is thin, though. We could not find a G2 or Capterra listing for the product, and Amazon's customer-review page for the device returned a server error during our research, so we couldn't verify sentiment there ourselves. The one outside data point we could pull was the Apple App Store listing, which shows a 4.6-out-of-5 average — including a reviewer citing three years of continuous use — but that rating is built on only 8 reviews, too small a sample to lean on heavily. One App Store reviewer also flagged a subscription-renewal price increase as a "scam," which the developer replied to by saying long-time customers were grandfathered at their original rate; we can't independently confirm how that older complaint squares with the lower current published renewal pricing, so we're flagging the discrepancy rather than resolving it.
How it compares to our top pick
BnBGenius is a flat $10/month AI layer (free for your first 500 messages) that handles guest messaging, phone concierge, task automation, review generation, and gap-night upsells — no PMS required. Party Squasher isn't really a competitor to that: it's noise/party-prevention hardware plus a subscription, built to solve a physical-security problem BnBGenius doesn't touch, and BnBGenius doesn't count phones on your property or replace an occupancy sensor. The two are complementary rather than substitutes — an operator could run BnBGenius for guest communication and upsells while running Party Squasher as physical early-warning gear on higher-risk properties.
