App Development
Building software applications for mobile or web that generate revenue through purchases, subscriptions, advertising, or by solving a problem valuable enough that businesses or consumers will pay for it.
App revenue models: paid download (one-time purchase to install), freemium (free with premium features behind a paywall), subscription (monthly or annual recurring fee — the most valuable model for app businesses), in-app purchases (buying virtual goods or features within the app), and advertising (showing ads to free users). Subscription apps are favoured by investors and acquirers because of the predictable recurring revenue.
You don't necessarily need to code to build an app — no-code tools like Bubble, Glide, and Adalo let non-technical founders build functional apps. However, for anything complex, hiring developers (through Upwork or a development agency) is the more common route if you lack the technical skills yourself. The hardest part of app development isn't building the app — it's distribution. Millions of apps exist; getting yours discovered without a marketing budget or existing audience is the real challenge most developers underestimate.
