It’s a fun niche. I’m making tens of dollars a month on my first app: https://apps.apple.com/us/app/audiowrangler/id1565701763?mt=... :)
The good thing is that usually you just keep growing from this. Now it’s making $1k per month, mostly because of sharing it with the world and implementing recurrent annoyances shared by users.
It’s important to have a way for users to contact you. I love Formspark.io for that, just slap a contact form on the app website and emails will start coming.
In my experience, knowing CSS is 90% of making a pretty and informative page. HTML is mostly just h1 for title, h2 for subtitle, div for groups and p for copy text.
I don’t like writing neither HTML nor CSS so my websites are written in Plim with Tailwind classes for styling.
Here’s a snippet that defines the icon on the https://lowtechguys.com/clop page
section#hero.min-w-[100vw].flex-center.flex-col.relative.pb-20
img.w-28.h-28.md:w-32.md:h-32.filter.drop-shadow-2xl src="/static/img/clop-icon.png"
h1.mb-6.text-4xl.text-zinc-600 Clop
h5.text-gray-500.m-0.p-0 Clipboard optimizer for images
h5.text-gray-500.m-0.p-0.-mt-1 Copy large, paste small, send fast
It’s not easy to understand nor pretty to read, but it makes for super fast iteration time, especially because of the responsive breakpoints (e.g. .flex-col.md:flex-row for a vertical layout on mobile and horizontal on desktop)
