Solo developer of a productivity app for the Mac for quite a number of years now. Yes, desktop apps are still very relevant and at least on the Mac, plenty of people willing to pay good money (unlike, say, the mobile market).<p>Whether to go desktop or web really depends on the application itself. Don&#x27;t try and shoehorn it into one or the other. Ultimately, you&#x27;ll need to find the right niche. Like in most industries, most people will fail (you usually don&#x27;t hear their stories) and success will most likely not be immediate.<p>Doing things solo is tough so some general advice:<p>- You are going to be wearing many different hats but if you can afford it, contract out what you don&#x27;t do well (like design, for many programmers).
- You have fewer resources but also a lower bottom line. Don&#x27;t expand without taking that into account, not just for the moment, but for the long term. It will affect how desperate you get with your revenue model.
- Don&#x27;t undercharge (especially if you go desktop). As mentioned, people still appreciate the value of desktop software.<p>Probably a lot more but those are the main ones plus I have support emails to deal with.
