However, the PM recently moved to app folio. 

@Cheree HarrisI was just recommended stessa and it’s free access from app or website with same interface.

I found this one surfing around https://jerrybarker.com/calcul... but we usually just average the income out then use https://propertytracker.com which isn't designed for STRs but works fine after averaging the projected income outside of the app.  

Lay everything out in Excel or do you use an app? 

Try asking your neighbor hosts on AirBnB and check an app called Nextdoor

I am seeking recommendations for companies or resellers that specialize in App/Card-based Washer/Dryers.

Their calendar view is really nice and immediately syncs with the channels.I can easily message guests from the app regardless of where they booked.

Shiny bells and whistles but no real benefit have lost more money from this app. 

That's why I don't use any OTA other than Airbnb, nor any cleaning app other than Turno, and nor any PMS other than Guesty or Hostaway! 

Beyond the usual maintenance requests and communication tools, are there any innovative technologies or apps you've implemented that have significantly improved the tenant experience?
