This is possibly the most interesting fumblebrag that I&#x27;ve read in a while. It has a few issues which have been hot on HN recently as well as some age-old problems.<p>The dependence on third-party services like maps, messaging, flight data, etc. is an interesting topic. Services that help you to get up and running in a couple of clicks are awesome at first. But they can become a burden when your usage goes up beyond a trivial amount. This is a great lesson about thinking ahead when choosing third-party providers - either by passing the expense along to your customers or having a roadmap to phase them out when you hit a certain volume.<p>Another point is the one-time pricing which, in my mind, is somewhat of a ponzi scheme for a business model. I always cringe a little when I see a cool new app with a &quot;one time payment for life!&quot; pricing. You just can&#x27;t support customers forever with a single lifetime payment unless you are earning revenue in some other way (i.e. advertising). It&#x27;s easy to think that you&#x27;ll continue to gain more customers forever, but you&#x27;re setting yourself up to be crushed by your own success. Unless you&#x27;re planning on regularly releasing new apps and&#x2F;or in-app purchases for your customers to purchase, it&#x27;s not a long-term business model.<p>Sorry to see the Just Landed go - it looked like a cool app. I think there is a lot to learn from this post so thanks to the author for posting.
