BuildBrief: The Stupidly Simple Way to Find Your First $10K App Idea
A simple approach to discovering profitable app ideas by solving your own problems.
What if I told you that you already know the best app idea, you just haven't built it yet...
And all you need to do - is solve your own biggest pain problem.
Everything else is just noise.
You already are the perfect customer
You buy things to solve your problems - like everyone else.
So all you need to do is figure out your #1 pain problem, then build an app as the solution to that specific problem.
Take the founder of PuffCount as an example. He was struggling to quit vaping, and so were his friends.
So, he built the simplest possible solution: an app that counts all your puffs. That's it.
No behavioral science and no fancy features. All it was is a simple button that you click every time you puff.
Now, that app pulls in $40K/month, and he sold it for $1M+.
Do this:
Find your daily pain: What do you and your friends complain about most? The thing that makes you go: "there has to be a better way."
The $10 test: Would you each pay $10/month to make this problem disappear? If not, find another problem.
Build the simplest version: Use AI to solve just the core problem. Ship fast to fail fast. If it sucks, you'll learn and build the next one faster.
Test it yourself first > then with friends/family > then market it.
Since you are the perfect user, you'll know exactly what to add next.
Stop looking for the "perfect" idea. You already know it.
Happy building!
