Zero-capital automation: running a business from Termux

Description and use

Automating price monitoring and email alerts with Termux and Python enables a steady side income using only a smartphone and free tools.

How to generate consistent side income using only a smartphone and free tools, without server or software costs.

Automated price monitoring and email alerts run on a smartphone, eliminating manual effort and server costs, enabling consistent side income.

Install Termux on Android
Use pkg to install python and pip
pip install requests beautifulsoup4
Write a Python script that fetches a product page, parses the price with Beautiful Soup, compares it to a target price, and sends an email via smtplib if the price drops
Set up a cron job in Termux to run the script periodically
Configure email credentials and SMTP settings in the script
Test the script manually, then rely on cron for automation

I’ve been quietly doing this for the last six months, building and iterating on automated tasks that bring in a consistent (and growing) side income.

pkg install python pip install requests beautifulsoup4
