How Much Does an App like Airbnb Cost

The approximate cost per platform to design an Airbnb user app for Android and iPhone is $15,000. It comes to about $30,000 for the Android and iPhone platforms combined.
The development of the backend, user website, and web services will cost approximately $20,000.
Total Cost and Duration
This kind of app would take three to four months to develop and would cost roughly $50,000 in total. Despite this, the app is simpler than those seen on websites like Uber. But a fully working website comes at an additional fee. Given that a website will bring in organic traffic from search engines, I would strongly advise including one.
