From Zero to $2,000/Month: My 9-Month Journey Building Profitable Mobile Apps as a Solo Developer
π Build your first profitable mobile app β without ads, without luck, without burning months.
Hi, Iβm Alexandre. Iβm a solo indie developer who spent years building apps that nobody downloaded.
In 2025, I decided to change everything.
I rebuilt my process from scratch.
I shipped differently.
I tracked more.
I experimented with paywalls, retention loops, and notifications.
I analyzed everything with my own analytics tool.
And in just 9 months, my apps went from $0 to $2,000/month organically β and growing:
No ads. No viral TikTok. No influence marketing.
This ebook is the complete playbook of everything I did to get there.
No fluff.
No theory.
No motivational nonsense.
Just real numbers, real mistakes, real insights, real screenshots, and a system you can use immediately.
Here is what I'll share with you
π How I increased my apps revenue by 50.14% in one month, 220% in 3 months (from September to November) and reach more than $2k/month, without shipping any new app:
π What I do to generate $60 to $100 every day:
π How I use programmatic SEO to bring thousands of visitors on my website, that then download my apps:
π How I turned 228 Google visitors in $85 of app sales in just one day:
π The paywalls I use to optimize conversion:
π How I make my users purchase again and again (without subscriptions):
π How I track my users and their purchases for them to spend even more:
To be short, in this e-book, I'll explain all the strategies I use to create apps with a good acquisition, conversion and retention, to have my home screen look like this every day:
